I have a C++/CLI assembly and it somehow needs msvcr120.dll (which is part of VC++ redistributable package 2013) to run. I discovered this by using tools to monitor which files the process is trying to load during running. Is there a way to get the required VC++ runtime version by looking into the dll and without running it? I tried to use ildasm.exe to look at the metadata but did not find relavant information.
Any suggestions? Thanks a lot.
If it's a mixed module (/clr), then the C Runtime will show up in its load-time dependencies:
dumpbin /dependents mymodule.dll
If it's a pure module (/clr:pure), then calls into the C Runtime will be via P/Invoke. You can disassemble the module and search for P/Invoke wrappers:
ildasm /text mymodule.dll | findstr pinvokeimpl
This will list the modules that may be dynamically loaded to satisfy P/Invoke calls. If the module depends on a C Runtime, you'll see it show up numerous times (you can further filter the list by searching for "msvcr" or "msvcp" if you're specifically interested in the Visual C++ libraries).
