Has anyone found a way to make the ADO.NET Entity Framework work with OLE DB or ODBC data sources? Specifically, I need to work with an SqlServer2000.
Visual Studio 2010 and EF4 do no longer support SQL Server 2000 - are you using VS2010??
Check out this page: http://msdn.microsoft.com/en-us/library/bb896309.aspx
Note
Starting with Visual Studio 2010, the
ADO.NET Entity Data Model Tools do not
support SQL Server 2000.

I try to use Entity Framework with a SQL Server Compact Edition database file, but when I try to update all models in VS, this message appears:
Can you help me please?
You can install "EF Core Power Tools", they include a simple DDEX provider for SQL Server Compact 4.0
Is there as way to create database diagram in Visual Studio as a Sql Server Project?
I know it is possible to do it in sql server management studio, but I am also wondering if it is possible to do in Visual studio.
As per MSDN (https://msdn.microsoft.com/en-us/library/y5a4ezk9.aspx) the Visual Database Designer was deprecated in Visual Studio 2013.
If you're using an older version of Visual Studio, note that support for the design tool within Visual Studio stops at SQL Server 2008 R2. (See "Important" box on top of page at https://msdn.microsoft.com/en-us/library/ms171976.aspx )
The short answer: no.
Actually there are two ways that i know In Visual Studio.
Add to project ADO.NET Entity Data model. It creates for you a .edmx file which contains a tables with relation.
More info MSDN. It also install Entity framework.
Open Server explorer > Connection to Database. Select Microsoft SQL Server, Server name=.; (or your PC name) and then choose your database schema.
You can check this video.
I hope it helps you.
Is there any framework for Windows Phone 8 which is similar in use to Entity Framework for generating POCOS from an existing database?
LINQ to SQL: A SQL Server Compact database combined with my SQL Server Compact Toolbox for the code generation. If you have VS Express, you can use the standalone edition, download from http://sqlcetoolbox.codeplex.com
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:

I'd want to stick with only the Express Editions. Is my use case one that Microsoft 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.
what are the new features (if any) in ADO.Net 3.5 as compared to 2.0?
According to this MSDN page ADO.NET 3.5 SP1 includes the following new "feature":
The .NET Framework Data Provider for SQL Server ( System.Data.SqlClient) provides full
support for all the new features of the SQL Server 2008 Database Engine
Also, I think the entity framework was introduced with that version.
I'm not aware of any major new features in straight ADO.NET itself. But the big new feature is LINQ to SQL and LINQ to Entities (about to come out with a major upgrade with .NET 4.0).
