DLL compilation error - assembly strong name

[Alan T]

I have a project references a DLL(by Add Reference), so far so good.
However, if I change my application from exe to a class library and also
added a reference to that same DLL, I got a compilation error:
"Assembly generation failed -- References assembly 'OrderController' does
not have a strong name"

That OrderController was developed by another developer, I am not sure by
..NET or Java.

[Marc Gravell]

Strongly named assemblies must reference strongly named assemblies.

So either apply a strong name to OrderController, or remove the strong
name from your assembly.
