Which program in Visual Studio lets me look into DLLs to see its API?

Question

See the question. I want to see the methods and classes offered by a DLLs library.

Answer 1

If you have limited options to download: In Visual Studio you could use Visual Studio Developer Command Prompt. Open it from windows menu -> All programs -> Visual Studio XX -> Visual Studio Tools -> Developer Command Prompt. Then: run command: ildasm

Example ildasm:

ildasm c:\MyNetAssembly.dll

If you have access to download any program you could use better options:
IlSpy
dotPeek
.net reflector
JustDecompile

For those coming from the old Visual Studio 6.0 days:

Dependency Walker is a nice free tool, that was formerly part of Visual Studio.
