Adding a controller with read/write actions and views, using Entity Framework - what is "Data Context class"?
29,696
The Data Context class is the top level EF object, the one that contains all your collections of entities that map to tables in the database.
The controller needs to be able to access this so that it can perform CRUD operations.

So in Visual Studio, when I go to add a controller, I get this dialog:
I was curious what Visual Studio would create if I chose "Controller with read/write actions and views, using Entity Framework", as I'm using EF.
So I set my Model class to a view model created, chose Razor for my views, but I don't know what Data context class is? The only thing in the dropdown is my view model I created.

Chris Sainty almost 13 yearsThe class generated from it. You should be using it any time you are writing code that talks to the database. The dialog appears to have selected the correct class, what is wrong with the generated code? -
