Entity Framework 4.1 code first SQL Server Compact 4 in Windows Form Application

I'm trying to use SLQ server compact edition 4 together with entityframework 4.1 with code-first approach in a Windows form application. In asp.NET MVC there are plenty of tutorials, but I can't find any help for windows form applications.

I d开发者_Python百科id the following steps:

• Created a windows form application
• Created a new project class library called "library_database"
• Created some classes and a DbContext
• Created a app.config file in the project and a connection string to a database file with name equal to my DbContext class name

Now when I try to access my DbContext to add a new object, the application hangs and doesn't stop without returning any exception.

How is this possible? Can you suggest me an approach, tutorial or anything to start? Consider that I can use EF code-first with asp.NET MVC but I never tried with windows applications

Thanks!
