  1. POUsing Ninject with Entity Framework 5 when I have a BaseController
    text
    copied!<p>My current stack is ASP.NET MVC 4 and Entity Framework 5.0. I installed ninject.mvc3 by NuGet and the code showed below works fine:</p> <pre><code>public class SessionsController : Controller { // use "kernel.Bind&lt;MyContext&gt;().ToSelf().InRequestScope();" // to inject MyContext private MyContext _context; public SessionsController(MyContext context) { _context = context; } [HttpGet] public ActionResult Login() { System.Diagnostics.Debug.WriteLine(_context.Users.Count()); return View(); } } </code></pre> <p>}</p> <p>Now, I want to extract a BaseController for my controllers: </p> <pre><code>public class BaseController : Controller { protected MyContext _context; public BaseController(MyContext context) { _context = context; } // I don't know what should be write here and // base controller must have a parameterless constructor public BaseController() { } } </code></pre> <p>Then I make SessionsController inherit from BaseController. When I run the code, an exception throwed that </p> <blockquote> <p>"Object reference not set to an instance of an object.(with MyContext)"</p> </blockquote> <p>Do I use Ninject wrong?</p> <p><strong>--UPDATED--</strong> the ninject's NinjectWebCommon.cs's code</p> <pre><code> /// &lt;summary&gt; /// Load your modules or register your services here! /// &lt;/summary&gt; /// &lt;param name="kernel"&gt;The kernel.&lt;/param&gt; private static void RegisterServices(IKernel kernel) { kernel.Bind&lt;TelesingContext&gt;().ToSelf().InRequestScope(); } </code></pre> <p><strong>--UPDATED--</strong> the edited SessionsController.cs code</p> <pre><code>public class SessionsController : BaseController { [HttpGet] public ActionResult Login() { System.Diagnostics.Debug.WriteLine(_context.Users.Count()); return View(); } } </code></pre> <p>}</p>
