How to connect to SqlExpress for Entity Framework using Visual Studio 2010 Express?

I'm trying to use the Visual Studio 2010 Express editions to set up an ASP.NET MVC 2 Web Application using SqlExpress + Entity Framework as the data access. I have both the "C# Edition" and "Web Developer Edition" installed.

If I try to add a data source using the "C# edition", I'm missing the "Microsoft SQL Server" data source type.

but Visual Studio 2008 Professional has it.

as noted by another StackOverflow question, the "Web Developer Edition" has this. However, the Web Developer Edition doesn't support the Entity Framework items: EntityFramework http://dl.dropbox.com/u/4163528/images/StackOverflow/2010EF.png.

I'd want to stick with only the Express Editions. Is my use case one that Micr开发者_如何学运维osoft forgot about? What can I do here to use SqlExpress + MVC 2 + Entity Framework?

Thanks!

You should be able to select SQL Server Database File, then change the connection string to connect to SqlExpress.

I just ran into this same problem. Visual Studio C# Express 2010 SP1 only offers me Microsoft SQL Server Compact 3.5 and Microsoft SQL Server Database File when creating or updating ADO.NET Entity Data Model (*.edmx) files.

However my copy of Microsoft Visual Web Developer 2010 Express SP1 is allowing me to add and update ADO.NET Entity Data Model (*.edmx) files in existing solutions and is allowing me to choose the Microsoft SQL Server option when building connection strings.

So the workaround for me is to simply switch between C# & Web Developer when messing with connection strings. Not sure if that's out-of-the-box for everybody or whether I've installed something else that switched the Microsoft SQL Server option on in Web Developer.
