If I try to fix the issue and build it I get this error when trying to devirt an assembly:

Make sure you have the correct version of AsmResolver downloaded (such as the dev branch).

KNIF commented 5 years ago

I used the dev branch, it built successfully and it devirts crackme's successfully, but when I try to devirt some bigger applications I still get the InvalidCastException.

Washi1337 commented 5 years ago

Seems like a bug then!

In the meantime, try using --salvage to ignore any errors that might occur during the recompilation.

Can you provide your "bigger application" that produced this error?

Can you provide your "bigger application" that produced this error?

I will send you the file in Discord DMs.

Washi1337 commented 5 years ago

I wouldn't mind the sample either ...

Is there a way where I can contact you privately and send the file? Discord, Skype, Email, etc.?

Edit: I sent you the file via RTN private message.

Make sure you're using the latest build 1x37x. If you still get an error like this, please don't hijack the issue and instead create a new one.
