Visual Studio 2010 SP1 and C++/CLI strong naming bug
Spanish version / Versión en Español This particular Visual Studio version has a bug which breaks strong naming signing for C++/CLI assemblies. Said bug is documented and has a workaround which requires editing a .Targets file. Details here . In case the link dies, I'll copy the steps below: Go to %ProgramFiles(x86)%\MSBuild\Microsoft.Cpp\v4.0\Platforms\Win32 . Open Microsoft.Cpp.Win32.targets with a text editor (this might require administrator rights). Search for <Target Name="LinkEmbedManifest" . Inside that tag, in the DelaySign attribute value, change % to $, and Link.DelaySign to LinkDelaySign (delete the period). Do the same for the KeyFile attribute (don't forget to change Link.KeyFile to LinkKeyFile).
