Entity Framework from .NET 3.5 with SQL CE 4.0
Is there a way to get the Entity Framework that ships with .NET 3.5 to work with SQL Compact 4.0?
I have a project that relies on .NET 3.5, and I can't move to .NET 4.0 yet, so Entity Framework 4 isn't an option. My existing code base works with .NET 3.5/EF 1/SQLCE 3.5 SP2, but on multi-threaded machines I get crashes now and then.
I'd like to move to SQL CE 4.0 to see if that resolves these issues.
After doing additional research, the answer to this is no. SQL CE 4.0 will only work with EF 4.
