Yes, a managed library contains .NET code (also called an assembly), an unmanaged library contains native code of some sort (C++, VB6 or similar).

External usually means that you didn't compile it yourself but use a 3rd party component.

To check whether as assembly is managed or not,

  • I open it in dotPeek. If it is .NET, it will say something like "msil", otherwise "not supported".
  • Another option is ILSpy, which will say "This file does not contain a managed assembly."
  • The tool ILDASM comes with the Windows SDK and says "no valid CLR header" in case of native assemblies.
  • You could also see if it has mscoree (.NET) as a dependency
