I need to know the equivalent SQL Server data types for EF. I found 2 similar online references, but their definitions appear inconsistent. Which reference should I refer to if I'm using Entity Framework?

1) Data Type Mappings in ADO.NET

http://msdn.microsoft.com/en-us/library/cc716729%28v=vs.110%29.aspx

2) SQL Server Data Types in the .NET Framework
