Purpose of EF 6.x DbContext Generator option when adding a new data item in Visual Studio

The DbContext Generator replaces the ObjectContext with much simpler and shorter code to connect Entity objects to database objects. A single database table with 30 fields is represented by about 800 lines of code as an ObjectContext but about 40 lines of easy to understand code as a DbContext and class generated by the DbContextGenerator.

The DbContext Generator creates two files –

1. creating the DbContext with connection string details and a DbSet for each table.

2. creating the class representing each table. If you open these .tt folders you will see the DbContext and classes generated. You don’t need to do anything with these classes – you refer to them in the Controller actions.
