differences between c#3.0 and c#4.0?

Vulpes · Answer

The differences between C# 3.0 and 4.0 (the language not the .NET Framework) are as follows: 1. Dynamic binding using the 'dynamic' contextual keyword. 2. Optional and named parameters. 3. Covariance and contravariance of type parameters for generic interface and delegate types. 4. Miscellaneous improvements to COM interop. All of these are worthy of articles in their own right. Search in particular the articles on this site.
