For more information on .NET Framework 4, please visit the .NET Framework Developer Center at http://msdn.microsoft.com/netframework. The .NET Framework 4 provides the classes developers need to create managed code applications for de- vices, windows, the Web, and servers and services. The .NET Framework provides a consistent API across dif- ferent deployment platforms including servers, desktop applications, and mobile devices. With Microsoft Silverlight™, .NET developers can write rich applications that run across platforms and browsers. The .NET Framework is available as a Client Profile download that provides the functionality for most desktop applica- tions with a download size that is 50 to 80 percent of the size of the complete Framework download.
