Breaking changes in .NET 4.0

by

The languages documentation team publishes separate documents for C# and VB breaking changes:

VB: http://msdn.microsoft.com/en-us/library/cc714070%28VS.100%29.aspx

C#: http://msdn.microsoft.com/en-us/library/ee855831%28VS.100%29.aspx

I wrote the C# one and included covariance and contravariance breaking changes mentioned by Eric Lippert, and events changes discussed by Chris Burrows. There are also some breaking changes around optional parameters, embedded interop types, and method group type inference.

Update:

One more useful document (from .NET documentation team): http://msdn.microsoft.com/en-us/library/ee941656%28VS.100%29.aspx
