How to inject DbContext in MVC 6 using default dependency injection?

Question

Can you please tell me how to inject a dbContext using the default dependency injection in MVC 6? Do I just need to create an interface and add it in the Startup.cs as below?

services.AddTransient<IMyDb, MyDb>();

Answer 1

you can inject the concrete type

public MyController(MyDb dbContext)

Answer 2

Yes, that should be enough. Then, as part of the controller parameters, add the interface and it will be injected:

class MyController
{
    public MyController(IMyDb dbContext)
    {
        // ...
    }
}
