How to debug strongly named assemblies

I used to avoid the strong name validation by sn tool. This is how I did:

Use sn -tp xxx.snk to get the token, then I added the token to registry at these two paths manually, they are HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\StrongName\Verification, and HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\StrongName\Verification\.

This did work for my application and I can debug in my local environment.

But when I use this in our new application, which is a version got upgraded from the old one, it's not working. When I start the application, this popup window just shows up.

And I actually don't know what's updated, maybe some new features added. I'm trying to fix some bugs in the new version.

Does anyone know what's happening here?

I tried with many ways avoiding the strong name validation searched online. But didn't work.

Following are the links I found about this issue:
