.net Framework Vs Win32 Api

[OCTOPUS]

Hi all, iam new to .net and i have some basic questions need to be clarified.
do .net base classes still use win32 api's internally or are they written from scrath.
if they were written from down level what is the language used to write them.like you know,win32 api's are c based.
thank you .

I think a lot of .NET apis map to win32 apis but .NET is its own language. It is not written in anything "down deep" .NET has its own compilers, tools, interpreters and APIs while still supporting some win32 stuff.

Take a look at the Wrox book Professional .NET Framework 2.0 by Joe Duffy. He explains in his book that Managed Code, any high-level NET language like VB or C#, is compiled into an Assembly (Metadata plus an executable written in Intermediate Language) which is taken by the CLR (Common Language Runtime) and compiled into executable code through a process called just-in-time (JIT) compilation.

Physically, the CLR is little more than a collection of DLLs containing sophisticated algorithms that interact with Windows via calls to various Win32 and COM APIs.
