I have two managed dlls: A.dll and B.dll. A.dll consumes B.dll.

If A.dll is not strong name signed and B.dll is strong name signed (or delay signed), when I run my program after build, it threw "B.dll not found, strong name validation failed".

Can an unsigned dll consume a signed or delay signed dll?

Thanks

Leon

Not possible.

You can cosume, but the problem is as you said B.dll is delay signed it means you can not run it or debug it. runtime will show error verification failed. To get rid of this during development or until you finally sign the dll:

use Sn.exe -Vr to skip verifaction during development.

But a strong name assembly can only reference strong named assembly to avoid DLL conflicts.
