I have created an EventReceiver that references a library I created in the same Solution (2 different projects). Whenever I add an item to the associated list I see this error in the log:

09/07/2012 15:29:19.20 ScriptEditor.exe (0x17BC)
0x1668 SharePoint Foundation General
6875 Critical Error loading and running event receiver PAR_NPI.ParSendComments.ParSendComments in PAR_NPI, Version=, Culture=neutral, PublicKeyToken=e49bc376710d17a9. Additional information is below. : Could not load file or assembly 'WCWC.SharePointExtensions, Version=, Culture=neutral, PublicKeyToken=9547592d373b2043' or one of its dependencies. The system cannot find the file specified.

I have ensured that the latest version of the dll is installed in the GAC. What exactly am I doing wrong here?

might sound sill and you probably have done it but have you done an iis reset after putting the dll in GAC?

or if that doesnt help would this?



dont know if that will be much help to you but i hope it is!

  • I had done an IIS reset. I have not done the steps in the first link. I'll check that tomorrow and let you know. Thanks for the response! Sep 8, 2012 at 2:47
  • The steps in this article blog.mastykarz.nl/… (marking as a safe control) fixed it. The link was in one of the comments on your StackOverflow suggestion. A simple thing I had forgotten to do! Sep 10, 2012 at 13:09
