Hello, I'm receiving the error at the end of the following log, with some generic types. I was able to reproduce the problem in the attached solution (please check README.txt). Thanks in advance.

[kOchirasu]

did you ever figure out the root cause for this?

Edit: I was able to use ILRepack and it did not have this problem.

[manuel-mp]

@kOchirasu never figured out. I simply abandoned the idea to merge certain projects, since I never received any help on this issue and I haven't the right know-how to solve it by myself. Anyway, thanks for the tip, I'll certainly give ILRepack a try!

EDIT: @kOchirasu I've tried ILRepack, no problem at all! I already migrated successfully every project requiring merge on it. Thanks a lot for your suggestion!
