I have an Addin that I am migrating to a VS package. I need to obfuscate it.
With the Addin, I follow these steps successfuly.
- Delay signing (either using project properties or [assembly: AssemblyDelaySignAttribute(true)].
- Build the project (Release build)
- Obfuscate the dll using Dotfuscator
- Sign the obfuscated version using sn -Vr from a bat file.
With the VS package version, I can't get past Step 2 above.
To easily recreate the problem ...
- Create a new C# project of type Visual Studio Package
- Run through the wizard leaving defaults for everything
- Build the project successfully
- Go to Project Properties > Signing > check Delay Sign Only
- Attempt to rebuild
Fails with following error stack.
