Note the network capture window. Click the Response body tab. In this task, you will prepare to enhance the Web API project created in Exercise 1 so that it can accept user input. Otherwise, you might continue using the End solution obtained by completing the previous exercise.
If you opened the provided Begin solution, you will need to download some missing NuGet packages before continue. Finally, build the solution by clicking Build Build Solution. One of the advantages of using NuGet is that you don't have to ship all the libraries in your project, reducing the project size. This is why you will have to run these steps after you open an existing solution from this lab.
In this task, you will augment the ContactRepository class of the Web API project created in Exercise 1 so that it can persist and accept user input and new Contact instances.
Add the following constant to the ContactRepository class to represent the name of the web server cache item key name later in this exercise. This example is for demonstration purposes and will use the web server's cache as a storage medium, so that the values will be available to multiple clients simultaneously, rather than use a Session storage mechanism or a Request storage lifetime.
Implement a new method named SaveContact to the ContactRepository class to do the work of saving a contact. The SaveContact method should take a single Contact parameter and return a Boolean value indicating success or failure. In this task, you will modify the default Index view of the web application to support the requirement of displaying the list of existing contacts in an HTML browser.
Replace the HTML code within the div element with id body so that it looks like the following code. Place a breakpoint on the Get method of the ContactController class. Once the page loads and the JavaScript executes, the breakpoint will be hit and the code execution will pause in the controller. Remove the breakpoint and press F5 or the debugging toolbar's Continue button to continue loading the view in the browser.
In this task, you will continue to modify the Index view of the MVC application. Add a new method to the controller class named Post as shown in the following code. Add the HTML code below to the file just after the unordered list you added in the previous task.
In ContactController. Once the page is loaded in the browser, type in a new contact name and Id and click the Save button.
When the debugger window breaks in the Post method, take a look at the properties of the contact parameter. The values should match the data you entered in the form. Step through the method in the debugger until the response variable has been created. Upon inspection in the Locals window in the debugger, you'll see that all the properties have been set.
The response following creation in the debugger If you press F5 or click Continue in the debugger the request will complete. Once you switch back to the browser, the new contact has been added to the list of contacts stored by the ContactRepository implementation.
This lab has introduced you to the new ASP. From here, you could create a new repository that facilitates data persistence using any number of mechanisms and wire that service up rather than the simple one provided as an example in this lab. The ability to host a Web API outside of a typical web application is also possible, as well as is the ability to create your own serialization formats. With code snippets, you have all the code you need at your fingertips.
The lab document will tell you exactly when you can use them, as shown in the following figure. The following instructions guide you through the steps required to install Visual studio Express for Web using Microsoft Web Platform Installer. There was an error sending the email, please try later.

The syndication template uses Internet Explorer during execution.
When you right-click your project in Solutions Explorer in Visual Studio, select Properties , then select the Debug tab and you can see the default address of the template.
Internet Explorer attempts to open the feed at this address. If you change the address of your feed, you must also change the address in the Debug tab. If you do not do this, Internet Explorer attempts to open the feed at the default address and fail. This template creates a Web service that provides data to a Silverlight client or front-end. The template can be added to a Web site or Web application project to create a WCF service, which includes service code and configuration that support communicating with a Silverlight client.
You can then use Add Service Reference to add a client proxy of the service to the client, and exchange data between the Silverlight client and the Silverlight-enabled WCF service. Therefore, information about the service can be obtained by all clients that connect to this service.
Messages exchanged between the service and the client are also not signed or encrypted.
