Question

This is my first ASP.NET MVC3 application and it is working and everything is fine except to open DB file (.sdf) in App_Data folder. I am getting error

the operation could not be completed. Unspecified error.

Things which is done from my side are:

1. All the operations like Show all files, Include in project etc.. are done on this folder and files.
2. SQL Server Compact 4.0 (runtime + tools support) is installed to my machine.

Thanks.

I had the same issue with MVC 4. Installing VS2010 SP1 fixed it for me.
