While I was going through the MVC 3 tutorial Accessing your Model’s Data from a Controller. I got the following error when I tried to open the Movies.sdf file.
“The Operation could not be completed. Unspecified Error.”
The first issue was I did not have Web Platform Installer set up within Visual Studio 2010 SP1.
After that was set, I needed to install Visual Studio 2010 SP1 Tools for SQL Server Compact 4.
SQL Server Compact 4.0 tooling is not installed along with Visual Studio 2010 SP1 by default.
Thanks! I was having the same issue.
Thanks great and to the point answer!!
thanks!- just the info I needed to know!
