I am developing an app with Entity Framework 4 and SQL Compact 4, using a Model First approach. I have created my EDM, and now I want to generate a SQL Compact 4.0 database
Probably need the SQL Server Compact 4 tools installed as well, if it did not install directly when Visual Studio 2010 SP1 was installed, you can install it. This is what worked for me when I had the problem.
