Silverlight and ASP.NET : Creating a Silverlight Application

Silverlight is Microsoft's foray into the RIA arena. The idea of the RIA has been gaining ground. More and more features closely associated with desktop applications have been moving into browser-hosted applications implemented through client-side scripting, AJAX, or browser plug-ins. Silverlight enables rich, client-style features for PC clients running the Windows operating system and Internet Explorer and Firefox, and Macintosh clients using Safari.

Microsoft ASP.NET 4 : Handlers and Session State & Generic Handlers (ASHX Files)

Generic handlers have an extension of ASHX. They're equivalent to custom handlers written in C# or Visual Basic in that they contain classes that fully implement IHttpHandler.

Microsoft ASP.NET 4 : HTTP Handlers - Handlers and IHttpHandler

Implementing IHttpHandler is simple—at least from the architectural standpoint. The ProcessRequest method takes a single parameter—the current HttpContext.

Microsoft ASP.NET 4 : HTTP Handlers - The Built-in Handlers

Remember that ASP.NET's configuration is very malleable and that you can choose to let clients see your source code by one of two means. You can remove the source code extension to ASP.NET mappings in IIS.

Microsoft ASP.NET 4 : ASP.NET Request Handlers

Although you haven't come across Web services yet, the WebService class implements the details required to interpret HTTP requests as method calls. Clients call Web services by packaging method calls in an XML format formalized as SOAP.

Microsoft ASP.NET 4 : Diagnostics and Debugging - Application Tracing

Application tracing shows you exactly the same details as page tracing, except they're held in memory and made available rendered as a different page and through a special HTTP handler that ASP.NET provides.

Microsoft ASP.NET 4 : Diagnostics and Debugging - Page Tracing

Turning on tracing is easy. Simply set the Trace property of the page to true. You can turn on tracing either by modifying the ASPX code directly or by setting the Trace property using the Properties window in the Visual Studio Designer.

Microsoft ASP.NET 4 : Caching and State Management - The Wizard Control: An Alternative to Session State

One of the most common uses for session state is to keep track of information coming from a user even though the information is posted back through several pages. For example, scenarios such as collecting mailing addresses, applying for security credentials, or purchasing something on a Web site introduce this issue.

Microsoft ASP.NET 4 : Caching and State Management - Tracking Session State

When an application needs to use session state, the runtime needs a way of tracking the origin of the requests it receives so that it can associate data with a particular client. ASP.NET offers three options for tracking the session ID—by cookies, the URL, or device profiles.

Microsoft ASP.NET 4 : Caching and State Management - Configuring Session State

ASP.NET gives you several choices for managing session state. You can turn it off completely, you can run session state in the ASP.NET worker process, you can run it on a separate state server, or you can run it from a SQL Server database

Microsoft ASP.NET 4 : Caching and State Management - Session State and More Complex Data

The ASP.NET Session object can store any object running in the CLR. That goes for larger data—not just small strings or other scalar types. One of the most common uses for the Session object is for implementing features such as shopping carts or any other data that has to go with a particular client.

Microsoft ASP.NET 4 : Caching and State Management - Introduction to Session State

To understand how session state works, this exercise involves creating a Web site with a page that stores a value as a member variable and as an element of session state.
