Question

I was just tryng to create a simple webpart in visual studio 2010 (for sharepoint 2010)
I created an empty sharepoint project, then added a webpart. I wrote a simple code (pasting it from a book with examples)
I Build the project, then deploy it (without errors)

Then when i go to the webpage where i want to add my webpart, i get this error when adding it:

“unhandled exception was thrown by the sandboxed code wrapper’s
Execute method in the partial trust app domain:
$Resource:core,ImportErrorMessage;”

Any idea about it?
If it’s needed i’ll post the code of the .cs file

Thanks

Answer 1

i don’t know why but the second try worked
i can’t say exactly what went wrong the first time, but i never get the same problem now
