What's a good local database with Entity Framework

What would be a good choice for a local database to use with Entity Framework for an WPF application that needs local databa开发者_如何学Pythonse.

I dont want to use MSSQL Server cos that'd be an overkill and or MSSQL CE cos few days back I was using SQL CE 3.5 and had all sorts of issues of it not supporting server generated IDs.

I've read MS Access has issues as well. and dont want to use SQLite either.

TIA

SQL Server Express sounds a good fit to me.

What about MySQL Embedded?
You can use either EF provider by Devart (it is a part of dotConnect for MySQL Professional), or the provider integrated into MySQL Connector /NET.
