NancyFx passing an Interface to a module constructor results in error

When I pass an interface into my module constructor it results in the error: Unable to resolve type: System.Web.HttpContextBase. Below is the Module code:

public class LeaderboardModule : NancyModule
{
    private readonly IUserService _userService;

    public LeaderboardModule(IUserService userService)
    {
        _userService = userService;

        Get["/"] = _ => View["Index"];

        Get["/NewUser"] = _ => View["NewUser.cshtml"];

        Post["/NewUser"] = _ => View["NewUser.cshtml"];

        Get["/UserList"] = _ =>
        {
            var userList = _userService.GetUsers();

            return View["UserList.cshtml", userList];
        };
    }
}

And here is the stack trace:

My initial thought is that it's an issue with the Nancy bootstrapper, so I decided to use StructureMap and I'm still getting the same error! Any help on this would be greatly appreciated

Solution

  • The stack trace tells you everything you need to know - your module has a dependency on UserService, and UserService has a dependency on JsonService, which has a dependency on HttpContextBase, which it can't resolve (because you shouldn't be using it really, or if you do, you certainly shouldn't have it as a constructor dependency)
