Is there an easy way to sign a C++ CLI assembly in VS 2010?

Question

Right now I am setting the Linker/Advanced/KeyFile option.

I am getting the \"mt.exe : general warning 810100b3: is a strong-name signed assembly and embedding

Answer 1

I ran into this problem with VS2010 SP1 for the WIN32 platform. Looking at the build .log file I found that the /KEYFILE parameter was given to the initial link for the .DLL, but after the manifest was created and the second link was done to include the manifest the /KEYFILE parameter was missing. After looking around a bit I found that the problem is in the file Microsoft.Cpp.Win32.targets in C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Platforms\Win32. There is a typo for the KeyFile attribute for the second link. I fixed it by changing line 441:

    KeyFile                        ="%(Link.KeyFile)"

to

    KeyFile                        ="$(LinkKeyFile)"

With that change the second linker pass included the /KeyFile qualifier and the .DLL was properly built with the publickey embedded.
