In which dot net CLR is built ?

If your question should read: "In which language dot net CLR is built ?", then Lakshmanan is correct that it's built using (unmanaged) Visual C++.

Initially, the C# and VB.NET compilers were built using Visual C++ as well but they have now been rewritten in C# and VB.NET themselves which will make it easier to expose the compiler API to .NET programmers and to add new features in future.

However, it wouldn't be a practical proposition to rewrite the CLR itself in a managed language and so I suspect this will always be written in Visual C++ or possibly a 'native code' version of C# if this should ever come to pass.
