I'm developing a Windows CE Mobile Application and using SQL Server Compact Edition as database server. However, I cannot drag and drop database tables from Server Explorer to a form's design view. It simply doesn't respond the drop. What could I be missing? I reinstalled and repaired everything. One note that I was able to do this operation a while ago. I also tried creating another database file and dropping tables of the famous Northwind.sdf.
Another thing is: I cannot generate a new data source within my project. When I try that the following error appears:
An error occurred while creating the new data source: An error occured while generating the data source.
The problem couldn't be solved any of the suggested operations, but the following one.
Start the Visual Studio from the command line:
C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe /resetskippkgs
And everything works just fine.
