As far as I know there are three tools that can be used to compare assembly versions:
- Microsoft's LibCheck which might be incorporated into your build server to have a document generated with your release that lists all the differences; This application outputs a xml-file with the differences;
- For ad-hoc investigation you should you ndepend;
- For simplicity you might use the free opensource Framework Design Studio; Which can also be incorperated into your build server using the "fxdiff.exe" found in the install folder. This application gives you a visual SourceSafe-like comparison.
I recommend using nDepend today! If you are not using it allready.
P.S. If you can't find the download for the Framework Design Studio click here.
