What distinguishes an.edmx file from a.dbml file in Linq? Which datasource in Visual Studio 2008 is preferable—edmx or dbml? Any issues with utilizing an edmx file in Visual Studio 2008? In VS-2008, can I use edmx?
The modeling file for Enterprise Framework is edmx.
The modeling file for Sql Linq 2 is dbml.
Entity Framework should be your primary focus since Linq 2 Sql is no longer supported.
