Andy McMullan's .NET FAQ

"This FAQ tries to answer some commonly asked questions about the fundamentals of the .NET Framework. By fundamentals I mean the nuts and bolts of how the .NET Framework works at a low level - topics like assemblies, garbage collection, security, interop with COM, and remoting. The most commonly-used parts of the class library are also covered. Other aspects of the .NET Framework such as ASP.NET, ADO.NET and WinForms are not covered."
