Controller with custom base controller not working

Update

Tried to clarify my problem

I have a ASP.NET 5 Web Api application. I'm trying to create a controller class that makes use of a custom base controller. As soon as I add a constructor to the base controller then MVC can no longer find the Get() end point defined in the Generic class.

This works:

When I navigate to /api/person then the Get() end point is triggered defined in the Generic class

Generic:

public class Generic
{
    public IEnumerable<string> Get()
    {
        return new string[] { "value1", "value2" };
    }
}

PersonController

[Route("api/[controller]")]
public class PersonController : Generic
{
}

This doesn't work When I navigate to /api/person then the Get() end point is not triggered. The only thing that is added is a constructor in both the Generic class and the PersonController class.

public class Generic
{
    protected DbContext Context { get; set; }

    public Generic(DbContext context)
    {
        Context = context;
    }

    public IEnumerable<string> Get()
    {
        return new string[] { "value1", "value2" };
    }
}

PersonController

[Route("api/[controller]")]
public class PersonController : Generic
{
    public PersonController(DbContext context) : base(context) { }
}

Is this a bug or am I doing something wrong?

Your problem has nothing to do with inheriting from another base class. I think the problem is, a proper implementation of your DbContext is not being injected to the constructor. Since asp.net 5 is so modular/dependency injectable, you need to explicitly configure it.

In the ConfigureServices method in your Startup.cs class, register your DbContext service so MVC will use that and inject that to your class controller when needed.

public void ConfigureServices(IServiceCollection services)
{
    services.AddEntityFramework()
        .AddDbContext<DbContext>();

    services.AddMvc();
}
