Ok, But is there any way i remove .demx project from my solution and generate model from there and add in my Model folder so i can use entity framework and there will no dependency for .edmx file and no warries about how heavy my edmx file is?

If you are using EF（DataBase-first or ModelFirst），you cannot leave edmx；however if you are using Code-First，you can！:-)

For more about Code-First，you can see this：

And you can download the latest Code-First dll file from NuGet.

Reguards！
