As I am using EF6 in my project and I have generated my edmx using VS2012 which uses by default "EF 5.x DbContext Generator" for generating edmx and all related code.due to which my edmx and all related code is for EF 5.0. So Can any one tell me what will be difference I will get in .tt and context.tt code files of edmx when I will generate my edmx from EF 6.x DbContextGenerator instead of EF 5.x DbContext Generator. I also have used EF 6.x DbContextGenerator and did not notice any change in edmx and related its code.
