I develop an SharePoint 2010 application with VS 2012. This application contains a third party dll that is embedded in the package manifest and deployed to gac. However, every time I deploy the application I receive following error message
Error occurred in deployment step 'Add Solution': Error: Cannot add the specified assembly to the global assembly cache:
I talked to the vendor of the dll and they told me that a .dat file (that is provided within their package) must be in the same folder as the dll.
This works for "normal" gac deployment (gacutl or copy the dll to gac) but not with the normal SharePoint approach. I simply try to add the .dat file as an assembly reference but then I cant deploy the application because only "real" dlls are allowed in the assembly definition section.
Does anyone know how to integrate a dll that requires a .dat file?
