Is it possible to modify assembly manifests other than by ILDASM/ILASM hacking?

Question

We have a customer who have two .NET assemblies, A and B:

• Assembly A references assembly B.
• Assembly A is unsigned, not obfuscated, no source code is available.
• Assembly B is signed, not obfuscated, there is source code available.

I want to modify assembly A and change the manifest so that instead of referencing a signed version of B, it references an unsigned version.

I know it's possible using ILDASM to dump the IL, edit the references then recreate using ILASM, but is there a better way?

Answer 1

It's seems that decompiling with ILDASM, editing the resulting IL and recompiling with ILASM was the path of least resistance.
