What are the new features in C# 2.0?

Support for all of the new framework features such as generics, anonymous methods, partial classes, iterators and static classes. See the .NET FAQ for more on these features.

Delegate inference is a new feature of the C# compiler which makes delegate usage a little simpler. It allows you to write this:

    Thread t = new Thread(ThreadFunc);

Instead Of This:

    Thread t = new Thread( new ThreadStart(ThreadFunc) );

Another minor but welcome addition is the explicit global namespace, which fixes a hole in namespace usage in C# 1.x. You can prefix a type name with global:: to indicate that the type belongs to the global namespace, thus avoiding problems where the compiler infers the namespace and gets it wrong.

Finally C# 2.0 includes some syntactic sugar for the new System.Nullable type. You can use T? as a synonym for System.Nullable<T>, where T is a value type. As suggested by the name, this allows values of the type to be 'null', or 'undefined'.

Does C# support multiple inheritance (MI)?

No, though it does support implementation of multiple interfaces on a single class or struct.

Does C# replace C++?

There are three options open to the Windows developer from a C++ background:
1.Forget C++ and use C#.
2.Stick with standard C++. Don't use .NET at all.
3.Use C++ with .NET. Microsoft supply a .NET C++ compiler that produces IL rather than machine code. (To make full use of the .NET environment (e.g. garbage collection), a set of extensions are required to standard C++, called C++/CLI.)

Each of these options has merits, depending on the developer and the application, but for most general purpose applications C# is a much more productive environment than C++.
Where existing C++ code must be used with a new application, the existing code can be wrapped using C++/CLI to allow it to interop with C#.

What is C#?

C# is a general-purpose object-oriented programming language designed by Microsoft. It is loosely based on C/C++, and is very similar to Java.
