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

I have just installed Entity Framework Power Tools Beta 4 into Visual Studio 2013. I am running a .NET framework 4.5 project, using Entity Framework code first with an Oracle database. I have installed the latest ODP.NET from Oracle (version 12), including the EF drivers, and I have Oracle.ManagedDataAccess and Oracle.ManagedDataAccess.EntityFramework referenced in my project.
This set up allows me to run my project and read and access data from the Oracle database. It all works fine. My problem is when I try to use the Entity Framework Power Tools. I can specify a connection using the Oracle database name and credentials, and the dialog says 'Test Connection succeeded'. However, after clicking the next button, I get the following error:
System.Data.ProviderIncompatibleException: The store provider factory type 'System.Data.OracleClient.OracleClientFactory' does not implement the IServiceProvider interface. Use a store provider that implements this interface.
I am confused because my project is able to use the installed ODP.NET as is to communicate with the Oracle database via Entity Framework. Most of the research I have done on the WWW suggests there should be a problem with versions and the contents of the web.config - but if this is the case surely I wouldn't be able to use EF with Oracle in my project without errors?
Is it just the case that the Power Tools do not work with Oracle?
Cheers!

As Christian says in his comment, you need to install ODP.NET as a provider that Power Tools can use. I did this by installing Oracle Developer Tools for Visual Studio.
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 am new to the subject of Entity Framework, I have a database in SQL Server 2005 and I'm working with Visual Studio 2012.
When connecting to the database with Entity Framework I get an error.
Cannot load file or assembly 'Microsof.SqlServer.Management.Sdk.Sfc,
Version = 11.0.0.0, Culture = neutral, publicKeyToken =
89845dcd8080cc91' or one of its dependencies. The system can not
locate an file specified.

Probably the solution to your problem: http://social.msdn.microsoft.com/Forums/en/vssetup/thread/5abfbb57-dac9-4039-b121-ae21c9b9352c

Where is SQL Server CE 4.0 data provider for Visual studio?
I want to use SQL Server CE 4.0 with Entity Framework. I have installed all packages but it's missed in list of available providers for EF?
Is it supposed to be so, or I miss something?
Probably need the SQL Server Compact 4 tools installed as well, if it did not install directly when Visual Studio 2010 SP1 was installed, you can install it. I had to do this myself.
Same as Title.
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??

Note
Starting with Visual Studio 2010, the
ADO.NET Entity Data Model Tools do not
support SQL Server 2000.
