Entity Framework generating separate classes

Question

I was using previous versions of entity framework and it was generating just one file for all classes . But I just upgraded to Visual Studio 2012 and now it generates a separate class files for each table . How do I change that ? I don't want 100s of class files and want them to be combined in one file/namespace .

You have to remove your T4 Templates (the *.tt files) an all the generate classes. Then open the *.edmx file. In the property window search for Code Generation Strategy and set it from None to Default .
Now the old template with the ObjectContext will be generatet. But I recommend using the T4 Template and its generated POCO classes. Thei're much cleaner and you can change the T4 template if needed.

And How can I modify the default code generation strategy for edmx?
