Programming Information

Explore in-depth technical information and get started building the next generation of applications and Web services using the .NET Framework.
.NET Framework Fundamentals

This section provides a set of resources to help you to understand the key concepts the .NET Framework is based on and learn how those concepts change the way in which you develop applications.

.NET Framework V2.0 Obsolete API List
These lists identify all of the APIs which are obsolete in the .NET Framework V2.0. These lists are meant to serve as a simple reference for obsoleted members and types.
Breaking Changes in .NET Framework 2.0
Breaking changes are changes in either the .NET Framework (runtime breaking changes) or Visual Studio (design/compile/project upgrade) that make certain application and development scenarios behave differently from the version 1.0 and 1.1 .NET Frameworks to the 2.0 version. Look up the class libraries you're using to determine whether any such changes will affect your application.
The Common Language Runtime (CLR)

The links in this section will help you understand the fundamental concepts of programming in the Common Language Runtime (CLR) environment.

Base Class Libraries Community

The links in this section will help you understand the fundamental concepts of programming the .NET Framework base class libraries.

Interoperability

How does a .NET application connect to unmanaged code, including COM libraries, ActiveX controls, and native (Win32) DLLs? This section includes links to resources to help you connect your .NET code to the unmanaged component(s) that you need to use.
