Check out Francesco Balena's books. I've read his book
"Programming Microsoft VB2005: The Language" and thought
it was excellent.  He has a corresponding book called
"Programming Microsoft Visual C#: The Language".

I also read "Practical Guidelines and Best Practices For
Visual Basic and Visual C# Developers". It was excellent,
and had a lot of tips about performance in it.

He has another C# book called "Programming Microsoft
Visual C# 2005: The Base Class Library (Pro-Developer)"
that's about the C# libraries.

And Brian Noyes' Data Binding book is really good, too,
if you're doing data binding, or want to know how to.

Hello Alan,

Which environment? .NET internals or what?
Have u read Richter books "Applied .NET" and "CLR via C#"? They are really
good

Not directly .NET ones but i found them interesting and useful

AT> I have been developing C# for 6 months and reading a couple C#
AT> books.
AT> However, to improve my .NET development knowledge and experience, I
AT> need few
AT> .NET books describing .NEt environment.
