I have a weird problem. I have a Sharepoint 2013 solution with two features, one of which has a feature receiver with some code in it. If I deploy this solution either through SPSD or Visual Studio 2013, I get an error

Error occured in deployment step 'Activate Features': Failed to load receiver assembly '...' for feature '...'

I can only deploy my solution if I delete the feature receiver, I don't even need to have any code other than that which Visual Studio generates in the receiver for it to fail. The deployment target of my solution is GAC, as I read somewhere else that feature receivers cannot be deployed to WebApps.

Can anybody help me here?

  • Do you have additional assembly(-ies) in wsp-package? If so, are they all deployed to GAC?

  • Yes, an external class library. Do you think this is causing problems? Sep 11, 2015 at 8:05

My solution to the problem was to change assembly version from to and build the SharePoint project. After that I deleted feature receiver and added feature receiver again so that feature manifest XML file gets updated with correct version of feature receiver assembly.
