tool for checking functions in assembly?

is there a tool to find all functions and classes in an assembly?

You could use reflection. Or Visual Studio. Or Resharper or Reflector or something. What exactly do you want to do?

I use a little freebie tool called ILSPY. It allows you to one step further and actually decompiles the IL into readable code so you can see how the stuff was implemented.

thanks people, I found out that ildasm is still in the SDK that was good enough. I needed to see if a certain function was in a deployed assembly to rule out if that was why my code was crashing.
ILspy is pretty nice too!
