DOWNHILL BIKES – A QUICK TOUR

Downhill Bikes – Tour the Current Site Overview of Part 04

Welcome to the Visual Studio .NET Guided Tour. This tour will cover the three key areas of the .NET developer experience: client applications, server applications, and XML Web services. Today, the computing industry is converging on a new model for building software, enabling an integrated world of software applications for businesses and individuals. This model enables a standard way of connecting software applications and exchanging information using the Internet. This new, Internet-based integration methodology, called XML Web services, enables applications, machines, and business processes to work together in ways never previously possible. In this tour, you’ll see how a fictional bicycle manufacturer takes advantage of XML Web services to improve customer service and operations. We’ll go through the steps as Downhill Bikes quickly adds functionality to its Web site to collect customer . Next we’ll add new capabilities so that customers can check on the status of their orders and management can view real- time Web page hits. Let’s start off by walking through the Downhill Bikes Web site as it stands today, by browsing the catalog, placing items in the shopping cart, and then placing an order. The Guided Tour will then step us through the addition of new client, server, and services features, using Visual Studio .NET.

PART 1: CREATING AN XML WEB SERVICE

Build an XML Web Service Overview of Part 14

In this part, we’ll build our first XML Web service in Visual Studio .NET. The Web service will demonstrate one of the key benefits of using XML Web services: Integration of disparate data sources into an easy to use data object. We’ll unite two different data sources, XML and SQL Server, into a single ADO.NET object called a DataSet. The DataSet serializes automatically as XML, and is returned by the XML Web service. XML Web services form the core business logic in the .NET application model. In an section, we’ll write a Microsoft Visual Basic® .NET program based on Microsoft Windows® that will use this Web service. Then, we’ll create Web and mobile interfaces as well. In each case, the logic in the XML Web service will serve as the core of the application, running separately from whatever presentation model we choose as appropriate for the situation. After finishing the Guided Tour, you’ll have a good understanding of the importance and power of XML Web services, and how Microsoft Visual Studio® .NET enables developers to quickly and easily build Web services, and incorporate them into business applications.

9

PART 1: BUILD AN XML WEB SERVICE

3 Step 1 of 7:

Add new Web service file 4

Adding a new file with the extension .asmx will instruct ASP.NET to treat the methods tagged with [WebMethod] as Web service calls. a. In the Solution Explorer, right-click DownhillBikes, click Add, then click Add New Item… . b. In the Templates list, click the Web Service icon. Leave the default name Service1.asmx. c . Click Open.

10

PART 1: BUILD AN XML WEB SERVICE 3Step 2 of 7: Add Customers table to the Web service4 Using the RAD features of Visual Studio .NET, create a connection to the Customers table by dragging it from the Server Explorer. a. From the View menu, click Server Explorer to open it. (Or, press CTRL+ALT+S.) b. Expand the Servers tree and locate the Customers table (Servers » computername » SQL Servers » computername » bikes » Tables).

c . Drag the Customers icon to the right, onto the design surface.

Optional If you would like to preview the data in the Customers table, right-click the Customers icon, and click Retrieve Data from Table. This is an easy way to quickly or modify the data in the table. Close this window with CTRL+F4 before moving to the next step.

11


3 Step 3 of 7: Add the Get and Update Web methods4 The GetData Web method will return a DataSet that combines the SQL data from Customers, and the Order data from the Orders.xml file. The DataSet can then be manipulated easily on any tier of the application. Even though these are two completely different kinds of data storage mechanisms, ADO.NET combines them into a disconnected in-memory DataSet for consumption by the XML Web service. a. From the View menu, click Code. F7 b. Click on the empty line above the comment: | // WEB SERVICE EXAMPLE This will position the insertion point in the right spot so that we can insert some code. c . From the View menu, click Toolbox. Or, press CTRL+ALT+X. d. Click the Guided Tour tab then double-click 1.3 WebService methods item to insert the code.

Optional You can remove the four comment tags (//) before HelloWorld() as shown in the following picture and recompile to see a simple WebMethod example.

12


3 Step 4 of 7: Build and test the Web service4 Here we build the page and test the Web service using a test page generated automatically by ASP.NET. This will allow us to see the data returned from the two data sources and show the results in a simple Web page. This is how quickly and easily you can build and deploy an XML Web service with Visual Studio .NET! a. From the File menu, click Build and Browse. CTRL+F8 b. Click the GetData hyperlink, then click Invoke. c . Examine the resulting schema and data for all customers and their orders.

13


3 Step 5 of 7: Add a new performance counter4 Using the Visual Studio .NET RAD server features, components and server-side resources, such as performance counters and message queues, are wrapped with programmatic interfaces, making them easy to program.

In this step, we’ll create a custom performance counter that will keep track of the number of times per second the new Web service method GetData is accessed. a. From the View menu, click Server Explorer. CTRL+ALT+S b. Expand the Servers tree and locate the Performance Counters (Servers » computername » Performance Counters). c . Right-click Performance Counters and click Create New Category . d. In the Category name box, type: bikes e. Click New. f. Change the Type list from NumberOfItems32 to RateOfCountsPerSecond32. We’ll go with the default name CounterName . Click OK.

14


3 Step 6 of 7: Use the performance counter4 Now we will update the performance counter by invoking it in our GetData method. One line of code is all we need to update the performance counter. Prior to Visual Studio .NET, simple steps such as these required hundreds of lines of code. a. In the Solution Explorer, right-click Service1.asmx and click View Designer. b. From the View menu, click Server Explorer. CTRL+ALT+S c . Expand the new bikes performance counter to locate CounterName. (Performance Counters » bikes » CounterName). Drag the CounterName icon to the design surface. d. Press F4 to view the properties of the performanceCounter1 object. Double-click the ReadOnly property to change it to False. e. Press F7 to view the code. f. Place the insertion point right before the return dataset line in the GetData() method. g. In the Toolbox, click the Guided Tour tab then double-click the 1.6 hit rate counter item.

15


3 Step 7 of 7: Test the performance counter4 Now we’ll show the performance counter in action by watching the counter increment as we use the XML Web service. a. Double-click hit_rate.msc in the Solution Explorer window. CTRL+ALT+L b. Switch back to Visual Studio .NET, and press CTRL+F8 to build and browse the Web service.

c . Click the GetData hyperlink. Click Invoke. Press the Refresh icon (Located on the left side of the toolbar) several times to requery the Web service.

d. Switch to PerfMon and you should see the performance counter move up and down, showing the number of requests per second this page is handling. e. Close PerfMon (don’t save the changes) and all browser windows. f. In Visual Studio .NET, from the Window menu, click Close All Documents. If asked to save changes, click Yes.

16

Summary In this first exercise you have accomplished many of the tasks that will drive the next generation of computing. You have built and deployed an XML Web service. You added business logic and database connectivity using the Visual Studio .NET Server Explorer. Most importantly, you created this XML Web service in minimal time using the RAD skills that today’s developers already have. Now that we have constructed and tested our XML Web service, we will build a series of client experiences that integrate the Web service into their functionality.

17

PART 2: RICH WINDOWS FORMS

Building a Rich Windows Form Overview of Part 24

Windows Forms is Microsoft’s next generation rich client forms package that breaks through the ceiling in desktop applications that once existed. Delivered as part of the .NET Framework, Windows Forms is available to all Visual Studio .NET developers, enabling developers to use the skills they possess today and the languages they know now to build the most powerful desktop applications ever. So, back to our sample company, Downhill Bikes. The company wants to add a smart client so that their call center staff can quickly retrieve details of customer orders as they field customer inquiries. We’re going to build a Windows Forms-based application using the Visual Studio .NET designer. Using a third-party control, we will then extend the form to add reporting, and we will call the XML Web service we built in Part 1. You’ll see how easy it is to build and extend Windows Forms with Visual Studio .NET, and how straightforward it is to integrate business data and logic residing in XML Web services.

18

PART 2: BUILD A RICH WINDOWS FORM

19


3 Step 2 of 9:

Add a data grid to the form4

Now we’ll add a data grid to the form. We’ll use the data grid to see customer and order data. We’ll be able to make changes directly in the grid, resize columns, change sort order and drill into the order data details. a. b. c. d.

From the View menu, click Toolbox. CTRL+ALT+X Locate the Windows Forms tab and click it. Double-click the DataGrid icon to add it to the form. Show the Grid Properties by pressing F4. Select the Dock property, type the letter T to change it from None to Top . Then, stretch the data grid until it fills the top two-thirds of the form. e. Drag a TextBox, a Button and a StatusBar onto the form below the DataGrid. (You may need to scroll down in the Toolbox for the StatusBar.) f. Click the Button and show its properties by pressing F4. Select the Text property and type: Search Your form should look like the following image:

20


3 Step 3 of 9:

Add a Web reference to our Web service4

Visual Studio .NET makes it easy to consume XML Web services in a Windows Forms application. In this step, we’ll consume the XML Web service we created earlier. a. From the Project menu, click Add Web Reference . b. Type http://localhost/DownhillBikes/Service1.asmx in the Address box. c . Click Add Reference .

21


3 Step 4 of 9:

Adding the Imports statements to our code documents the namespaces we are using. Doing so reduces the code a developer has to type by eliminating those namespaces from the written code. a. b. c. d.

From the View menu, click Code. F7 Add a new, empty line at the top of the file. From the View menu, click Toolbox. CTRL+ALT+X In the toolbox, click the Guided Tour tab and double-click on 2.4 Import statements to insert the two import declarations:

22


3 Step 5 of 9:

Add the Visual Basic. NET source code4

This code will complete the loop, referencing and calling the XML Web service, taking the data DataSet returned and binding it to the DataGrid on our form.

a. b.

Position the insertion point on the line above the End Class statement. Double-click on 2.5 VB methods to insert all the code.

23


3 Step 6 of 9:

Run the program and make changes4

The DataGrid automatically senses the shape of the XML data and adds a plus sign to let the drill into customer order details. The DataGrid also allows sorting of columns and editing of data if security permissions are met.

Important • In the following steps, you may press the F5 key as a shortcut to build and run the project. Please make sure that the GuidedTour Add-in Tool Window does not have focus when you use F5. Pressing F5 when the GuidedTour Tool Window has focus will cause it to go to part 0. (If this happens, you can simply navigate back to this step.) a. From the Debug menu, click Start to run the application. (Or, press F5.)

b. Expand a customer record (by clicking the + in the left-most column) and click CustomerOrders to view its orders. c . Expand an order record and click OrdersDetails to view its details. d. Click the left -arrow icon twice to return to the customer records.

e. f. g. h. i. j.

Type you in the box next to the Search button. Click Search. Change Rob Young to Robert Young and press the DOWN ARROW key. Close the Form1 window. From the Debug menu, click Start to run the application. (Or, press F5.) Note that the change made in sub-step g is persistent. Close the Form1 window.

Important • If the CustomerService program doesn’t start, make sure it’s your default project. In the Solution Explorer, right- click CustomerService , then click Set as StartUp Project.

24


3 Step 7 of 9:

Stop the Web service4

Stopping IIS will stop the XML Web Service. Once we do this, the rich Windows application will switch to offline mode, giving the full access to the data. a. Click the Windows Start button and choose Run. [WINDOWS KEY ÿ] + R b. In the Open box, type iisreset /stop and click OK.

25


3 Step 8 of 9:

Try it again4

With the XML Web service offline, access to the application data is not available. The Microsoft .NET Framework provides built-in Web caching to our application when we use ADO.NET which enables the offline scenario.

a. In Visual Studio .NET, from the Debug menu, click Start to run the application. (Or, press F5.) b. Note the status bar displays Working in offline mode . c . Change the of Robert Young to abc and press the DOWN ARROW key. d. Close the Form1 window.

26


3 Step 9 of 9:

Start IIS and run once more4

When we start IIS and access our Windows application, we will see our offline data has been added to the SQL Server 2000 Database, completing the reconnect portion of the offline scenario. a. Click the Windows Start button, then click Run… . (Or, press [WINDOWS KEY ÿ] + R.) b. In the Open box, type iisreset /start and click OK. c . After the console window appears, wait for it to close by itself. c. In Visual Studio .NET, from the Debug menu, click Start to run the application. (Or, press F5.) d. Note that Robert Young’s is abc and the status bar says Connected to WS. e. Close the Form1 window. f. In Visual Studio .NET, from the Window menu, click Close All Documents . If asked to save changes, click Yes.

Summary You have just completed the construction of a data-bound smart client application using Visual Studio .NET and the Windows Form designer. In this exercise, we incorporated the XML Web service built in Part I to extend the functionality of our Windows Form application. The next step in our Guided Tour will introduce us to the power and breadth of the Visual Studio .NET extensibility model and Crystal Reports for Visual Studio .NET.

27

PART3: EXTENDING THE RICH WINDOWS FORM

Experience the Extensibility of Windows Forms Overview of Part 34

Visual Studio .NET is a highly extensible development environment. Over 100 ISVs will be shipping new .NET versions of their tools and add-ons for Visual Studio .NET. You’ll find a special version of Crystal Reports integrated directly into the Visual Studio .NET IDE. Crystal Reports fills an important role in the application development process by providing developers with a productive, integrated, and RAD experience for creating highly interactive relational data reports. These reports can be generated for the entire array of .NET application types, including XML Web services and Web-based solutions, as well as Windows-based applications running on desktop PCs and mobile devices. Downhill Bikes management would like to enhance their application with a new reporting capability. The new report will enable them to drill into customer orders and look for trends in customer spending. Proceeding with our tour, we will use Crystal Reports to extend our existing smart client with built -in reporting.

28

PART 3: EXTEND THE WINDOWS FORM

3 Step 1 of 6:

Add a new Visual Basic. NET Windows Form4

We will add a second Windows Form to our project to contain the Crystal Report we build in the next step. a. In the Solution Explorer, right-click WindowsApplication1, click Add, then click Add New Item… . b. In the Templates pane, click the Windows Form icon and click Open (the default Name of Form2.vb is fine).

29


3 Step 2 of 6:

Let’s run the application and examine the rich report. a. b. c. d.

From the Debug menu, click Start to run the application. F5 Click Button2 to open the report. Maximize the Form2 window. Double -click an entry in the Order Date column to get order details.

e. Close the Form2 and Form1 windows. f. In Visual Studio .NET, from the Window menu, click Close All Documents. If asked to save changes, click Yes.

Summary In this step of the Guided Tour, you successfully incorporated a Crystal Reports viewer into the Downhill Bikes smart client application. This exercise illustrates the power of the Visual Studio .NET extensibility model by showing how third-party tool and language vendors can seamlessly integrate their products directly into Visual Studio .NET. In the next step of the Guided Tour, we’ll delve into Web application development and the use of Application Center Test to analyze the load performance of our Web applications.

34

PART4: BUILD A WEB FORM AND LOAD TEST

Building a Web Form and Test for Scalability Overview of Part 44

With Visual Studio .NET and Web Forms, developers can rapidly develop Web applications that run in any browser on any operating system using the same techniques previously used to build form-based desktop applications. Application Center Test (ACT), a new feature integrated with Visual Studio .NET Enterprise Architect, enables developers to gather performance metrics and perform functional testing of XML Web services within the Visual Studio .NET development environment. Before Downhill Bikes goes live wi th their new application, they would like to know that it will scale well. Using a built-in tool like Application Center Test, their developers and testers can see the immediate effects of the changes they make in the performance of their application. In this part, we will build a Web Form that accesses the previously built Web service. Then we will load test the Web service with ACT.

35

PART 4: BUILD A WEB FORM AND LOAD TEST

3 Step 1 of 6:

Add a new ASP.NET Web Form built with C #4

Using a built-in template in Visual Studio .NET, we will add a new Web Form for our Orders status page. a. From the View menu, click Solution Explorer. CTRL+ALT+L b. In the Solution Explorer, right-click DownhillBikes, then click Set as StartUp Project. c . From the File menu, click Add New Item. CTRL+SHIFT+A d. In the Templates pane, click the Web Form icon and type Orders.aspx in the Name box. Click Open.

36


3 Step 2 of 6:

Add an ASP.NET DataGrid 4

Dragging a DataGrid from the Web Forms toolbox provides an easy way to visually compose Web applications. The DataGrid is analogous to the grid control we used earlier on a Windows Form. The difference is that the Web Forms version will render HTML, though the developer working with these two controls will see little difference between them, providing a consistent development experience and shorter learning curve for developers new to the Web. a. b. c. d. e.

From the View menu, click Toolbox. CTRL+ALT+X Click the Web Forms tab in the toolbox. Double-click the DataGrid icon. From the View menu, click Code. F7 Position the cursor on the comment line for Page_Load:

f. Double-click the 4.2 Orders Page_Load() item in the Guided Tour toolbox. The code should now look like this:

37


3 Step 3 of 6:

Secure access to the Orders Web Form4

Using the Web.config file, we can lock down access to this page so that only authenticated s have access. This file is part of a hierarchy of configuration files that make it easy to secure Web applications built with Visual Studio .NET. a. From the View menu, click Solution Explorer. CTRL+ALT+L b. Double-click the Web.config file (it’s the last file in the list). c . Locate the line (note the “/” before the word “location”).

d. Position the insertion point below that line, press the Enter key, and doubleclick 4.3 Authenticate.

e. Right-click the Orders.aspx file in the Solution Explorer and click View Code. f. From the File menu, click Build and Browse to view the new Orders page. (Or, press CTRL+F8.) g. Notice you were first directed to the page. Click sign in . Now you should see the orders for the customer you logged in as (CustomerID is 1).

38


3 Step 4 of 6:

Start Application Center Test (ACT)4

ACT provides sophisticated testing capabilities so that developers can analyze relative performance by simulating load on their Web applications, including XML Web services.

We will use ACT to see the affects of adding an output caching directive to our Web Service. Output caching is a new feature of ASP.NET which enables the reuse of cached pages, thus saving server U cycles and increasing perceived application performance. a. From the Windows Start menu, select All Programs (Programs in Windows 2000), then Microsoft Visual Studio .NET, then Visual Studio .NET Enterprise Features . From there, click Microsoft Application Center Test.

39


3 Step 5 of 6:

Build a new ACT Test Script4

Using the built-in Wizard it is very easy to start using ACT. The recording feature records a session we can then play back to generate load and stress our application. a. From the Actions menu, click New Test. b. Click Next on the Welcome screen. c . Click Record a new test. Click Next twice. e. Click Start recording.

f. Navigate to http://localhost/downhillbikes/orders.aspx in the browser window that is launched by Application Center Test. Click the sign in button. Then close the browser—you’ve finished recording your simple script. g. Switch back to Application Center Test and click Stop recording.

3 Step 6 of 6:

Add Page Output Caching4

While the page is under load, we’ll turn on page caching, with just one line of code. The increase in the number of pages served per second should jump dramatically. Notice that ASP.NET does not require us to stop or disrupt the Web site when we update a page. We just save the page and the changes take effect immediately. a. Click the orders test item in the left pane.

b. From the Actions menu, click Start Test. CTRL+F5 c . Once the test has started, click Show Details.

d. While the load test is running, switch back to Visual Studio .NET. e. From the View menu, click Solution Explorer. CTRL+ALT+L f. Double-click the Orders.aspx file. g. From the View menu, click HTML Source. CTRL+PgDn h. Place the insertion point at the beginning of the second line: |
42

i. Double-click the 4.6 Output Cache code snippet.

j. From the File menu, click Save All. CTRL+SHIFT+S k. Switch back to the Test Status window. Click the Show Details >> button to see the graph. You should see a jump in the number of Requests per Second (RPS) being served up by the page. Since the page is cached (for 10 seconds at a time), we’re drastically reducing the number of database calls.

l. Close the Application Center Test windows. m. In Visual Studio .NET, from the Window menu, click Close All Documents. If it asks to save changes, click Yes.

Summary Part 4 of the Guided Tour enabled us to build an ASP.NET Web application and test it using Application Center Test (ACT). The Web Form-based application we built was constructed using the same development paradigms previously used to build form-based desktop applications – effectively leveling the learning curve to Web application development. We then employed ACT to load test our Web application to ensure scalability in a production environment. In Part 5, we’ll integrate the functionality of third-party XML Web services into our Web application.

43

PART 5: INTEGRATE XML WEB SERVICES

XML Web Services at Work Overview of Part 54

XML Web services will revolutionize software development both inside and outside the firewall. Visual Studio .NET makes it easy to create and consume Web services, using the familiar metaphor of the application component. Developers using Visual Studio .NET can simply right-click in the Solution Explorer window and select “Add Web Reference.” From there, they need only supply the URL to the Web service on their intranet or the Web, or browse the UDDI (Universal Description, Discovery, and Integration) registry to locate desirable Web references. The Web service is then available for use from within Visual Studio, with statement completion and other IntelliSense features automatically ed. When Downhill Bikes wants to implement a new service for customers, the company needs tools to help their developers turn ideas into implementation. By using Visual Studio .NET, developers can add new functionality in a matter of hours, not days. In this part of the tour, you’ll add a Web reference to a third- party Microsoft partner to the Web application. The new functionality will enable Downhill Bikes to offer gift certificates to its customers. You will then add a Web reference to a service provided by one of DownhillBikes’ partners so customers can find authorized bike stores to redeem their certificates.

44

PART 5: BUILD A WEB PAGE - ORDERS

3 Step 1 of 8:

Add an image to the page4

In this step you will add interface elements to the thank you page to offer a gift certificate to a Downhill Bikes customer as they complete a transaction.

Important • The following step requires an Internet Connection. a. Double-click ThankYou.aspx in the Solution Explorer. CTRL+ALT+L b. Display the Web Forms toolbar by pressing CTRL+ALT+X and clicking the Web Forms button. c . Drag an Image control from the Web Forms toolbar bar into the lower-right cell. The image will be populated dynamically from the Web service.

45


3 Step 2 of 8:

Click Add to Cart, and then click Checkout.

e. Click Sign In, then click Place Order. f. Note the dynamically-generated text in the gift certificate, created through a Web service.

48


3 Step 5 of 8:

Add the bike store finder service4

In this step we will integrate another Web service to find locations of authorized and convenient bike stores where we can redeem our gift certificates. This Web service interaction is more complex than the previous, in that we’ll be ing the ’s zip code to the service, and using that to locate and return a list of nearby stores.

a. Click the DownhillBikes project in the Solution Explorer. b. From the Project menu, click Add Web Reference. c . Type http://www.bikestorefinder.com/locator.asmx in the Address box. d. Click Add Reference.

49


3 Step 6 of 8:

In this step, we will enhance our Web Form by adding additional interface elements to the page. Note how similar this experience is to the Windows Forms design experience. a. Double-click the ThankYou.aspx page in the Solution Explorer. b. Position the insertion point after the Image and press ENTER. Type: c. d. e. f.

Enter your ZIP code for stores nearest you

Drag a TextBox onto the form, below the text you previously entered. Drag a Button to the right of the TextBox and press F4 to show its properties. Change the Text property to Search. Position the insertion point after the Search button and press ENTER. Drag a Label below the TextBox. Your screen should look like the following:

50


3 Step 7 of 8:

Add code to handle the button click4

The code behind the button will set a reference to the Web service and send the ’s zip code to it, returning an XML-based list of bike stores that we will then append to a label control on the page. a. Double-click the Search button to add a server-side event handler. b. Double-click 5.8 ThankYou: Store locator.

c. On the Build menu, click Build Solution. CTRL+SHIFT+B

51


3 Step 8 of 8:

Start the application and test it. a. From the Debug menu, click Start Without Debugging. CTRL+F5 b. Click add to cart then checkout . c. Click sign in then place order . d. Type your ZIP code in the box and click the button. e. Note the location of the stores near to that ZIP code.

f. Close the browser. g. In Visual Studio .NET, from the Window menu, click Close All Documents. If asked to save changes, click Yes.

Summary In this part of the Tour, you used the built-in for UDDI that is found in Visual Studio .NET to discover and incorporate a Web service from third-party partners to your Web application. The new functionality enables Downhill Bikes to both offer gift certificates to its customers find authorized bike stores where they can redeem their certificates.

52

PART 6: BUILD A MOBILE WEB PAGE

Building a mobile Web Form Overview of Part 64

The Microsoft Mobile Internet Toolkit (MMIT), available as an add-on to Visual Studio .NET, provides the tools to enable mobile Web application development. MMIT makes it easy to build a single mobile Web-based application that will automatically generate HTML, compact HTML (cHTML), or Wireless Markup Language (WML), depending on the target device's capabilities, and do so using business logic in XML Web services. Now with MMIT, targeting multiple devices with a single Visual Studio .NET application is as seamless as building a rich Windows-based desktop application.

Having added new gift certificate capabilities to its site in the previous part, Downhill Bikes now needs an easy way for their dealers to validate the gift certificates online. They also want an easy way for their customers to check the balance of their gift certificates online. In this part you will use the Mobile Web designer in Visual Studio .NET to build a Web page that can be accessed by a variety of devices, giving DownhillBikes’ dealers and their customers complete flexibility in running the mobile Web application.

7: Summary4

The Visual Studio .NET Guided Tour covered three areas: building client application, web- based server applications, and XML Web Services. The Microsoft .NET platform pivots itself around these 3 fundamentals that are driving the digital revolution. First, the platform was built in concert with the Microsoft strategy around XML Web services – the crucial factor in solving the pressing problem of software and business integration. Second, Microsoft .NET provides the underlying substrate to deliver client experiences tailored to the desktop PC, the thin-client Web browser, and to the multitude of emerging smart devices. Finally, the Microsoft .NET platform recognizes the need for enterprise-critical server software and integration. Visual Studio .NET represents the cornerstone to the Microsoft .NET platform. It is the tool that developers will use to drive their organizations and their customers into the world of XML Web services. Like the .NET platform itself, Visual Studio .NET aligns itself around the essentials of his digital revolution – XML Web services, Clients, and Servers.

By providing the most efficient way to both build and consume XML Web services, Visual Studio .NET keeps developers on the vanguard of next generation application development. In addition, Visual Studio .NET extends the concept of RAD to every facet of the client experience, enabling developers to build desktop, Web, and mobile applications using the skills they already have and the languages they already know. Finally, Visual Studio .NET demystifies server-side development – providing RAD development of business logic, supplying the tools needed to deploy data-rich Internet applications, and delivering the premier suite of enterprise servers to satisfy every business need. With Visual Studio .NET, the once unattainable goals of developers and organizations alike are finally brought within reach. Empowering organizations to seamlessly move to the world of XML Web services, delivering resources for every client experience, and addressing the issues of server development and integration – Visual Studio .NET unleashes the power of .NET.

Summary The final part to the Guided Tour provided an introduction to the Microsoft Mobile Internet Toolkit (MMIT). MMIT provided a forms-based visual interface to build mobile applications for a variety of emerging smart mobile devices.
