I'm trying to deploy my package (via VS 2010) and getting this error.
"Error occurred in deployment step 'Add Solution': Error: Cannot add the specified assembly to the global assembly cache: SPSureCommon.dll."
I tried to use GacUtil but it whines about the dll being 'in-use'... so I ran Process Explorer and about 10 processes have loaded the DLL for some reason.
The only way I've figured out how to update these common dlls is to kill every using process, delete it via GacUtil and then reboot the server.
There has to be a better way...
What am I missing?
