Loader for .NET Assemblies

[Turkuaz]

Hello all,
I am working on a programme written in c#. I can not patch the executable files on the disk because of integrity checking.

I would like to patch some part of dll's after they are loaded into memory, I mean a loader.

Is it possible? If yes any guidance and help will be highly appreciated.

Thanks

I just did a quick write-up/tutorial on forcing .NET Framework apps to load modified assemblies. I'm not sure of your needs but perhaps you might find it useful:
