I have compiled a Sandboxed webpart and deployed it to the Sharepoint 2010 server. However, when I try to add it to a page I get the following error
Unhandled exception was thrown by the sandboxed code wrapper’s Execute method in the partial trust app domain: $Resources:core,ImportErrorMessage
I’ve included my Sandboxed Webpart code below. I can’t work out how to fix this error, or work out what is causing the problem
