I deployed my WSP to the SP server and activated my solution. When I attempted to add my web parts to a page I get the message:
A Web Part of Web Form Control on this Page cannot be displayed or imported. The type is not registered as safe.
After more research I added the SafeControl attributes to the manifest file. I was able to update it again but now I get this error when I add a web part on the page:
Web Part Error: Unhandled exception was thrown by the sandboxed code wrapper's Execute method in the partial trust app domain: An unexpected error has occurred.
Also checked the web.config and I see entries that look correct. My project DLL file is also in the GAC.
Any other ideas?
