I have "mycomp.myassembly.dll" in GAC but Load and LoadFrom throws file not found exception and LoadWithPartialName returns null. I'm doing the following:

    AssemblyName name = new AssemblyName();
    name.Name = "mycomp.myassembly.dll";

    Assembly assembly = Assembly.Load(name);

fails with FileNotFound for mycomp.myassembly.dll file, and

    Assembly assembly = Assembly.Load("mycomp.myassembly.dll");

fails with exactly the same message.

I double checked that assembly is in GAC (and even did gacutil /if for it again) and it does work in all other cases, I just unable to load it myself.

What am I doing wrong here? Do I miss something?

Have you tried using the fully qualified assembly name? (e.g. "ycomp.myassembly.dll, Version=1.0.2004.0, Culture=neutral, PublicKeyToken=8744b20f8da049e3")
