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

  • ILSpy is an open-source tool which allows you to browse an assembly's packages and classes and also to decompile code.

  • Another free-of-charge tool is JetBrain's dotPeek.


This is exactly what the Object Browser is for.

  • Add a reference to the DLL.
  • Right click it in the list.
  • Click View in Object Browser.

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.

I like it still. Here is a screen shot:
