It is likely that this is happening because I installed Net 4.5 and Firebird provider stopped working. Thus, I uninstalled 4.5 and reinstalled Net 4.0 and Visual Studio 2010.
When executing a Stored Procedure is the error message: "Could not load type 'System.Runtime.CompilerServices.ExtensionAttribute' from assembly 'mscorlib, Version = 4.0.0.0, Culture = neutral, PublicKeyToken = b77a5c561934e089'." This error is related to the existence of the Net 4.5, right?
Where should I change my source code so that it is in the form of .Net 4.0? It took me 3 days to reinstall the system again and wonder, if necessary, the Firebird's provider works with .Net 4.5?
Thanks,
Marco Castro

You're very likely using .NET 4.5 (with EF5) version on .NET 4.0 (no EF5).
