I have a web application that uses .NET Framework 4, MVC 4, Ninject 3.

  • 0

I have a web application that uses .NET Framework 4, MVC 4, Ninject 3. Originally I was using .NET Framework 4.5 but I changed the “Target Framework” to 4.0 and fixed all the errors it caused. Now the application runs perfectly on my local box. The problem is that when I deploy it to Azure I get the server error at the bottom of this post.

I have seen this error before. When I was first starting to use Ninject I would get this error when I wasn’t binding correctly in the Global.asax (relevant code below).

Also, my Ninject.dll reference “Copy Local” property is set to “True”.

What am I doing wrong? Why am I getting this error when I try to view the web application in Azure but not on my local box?

Thank you for your help,

Aaron

HomeController.cs:

public class HomeController : Controller
{
    IAuthorizationService _authorizationService;
    IUserService _userService;

    public HomeController(IAuthorizationService authorizationService, IUserService userService)
    {
        _authorizationService = authorizationService;
        _userService = userService;
    }
}

Global.asax:

protected void Application_Start()
{
    SetupDependencyInjection();
}

private void SetupDependencyInjection()
{
    //create Ninject DI Kernel
    IKernel kernel = new StandardKernel();

    //register services with Ninject DI container
    RegisterServices(kernel);

    //tell asp.net mvc to use our Ninject DI Container
    DependencyResolver.SetResolver(new NinjectDependencyResolver(kernel));
}

private void RegisterServices(IKernel kernel)
{
    kernel.Bind<IAccountService>().To<AccountService>().WithConstructorArgument("connectionString", ConfigurationManager.ConnectionStrings["AccountManagerEntities"].ConnectionString);
}

    Sandrino Di Mattia, you are correct, I need to register the other interfaces. Actually, I do have them registered. For the sake of being to-the-point in my example code I cut out portions that were relevant. :p

    The way I fixed it was merely uninstalling Ninject with NuGet and then re-installing it with NuGet. I had read an article on the internet that said that I’d have to do this with Entity Framework to allow it to install properly with .NET 4.0 after re-targeting from 4.5. So, when that solved my EF problems I tried it with Ninject and it worked.

    So, the moral of all this is when re-targeting from .NET 4.5 to .NET 4.0, uninstall your NuGet packages and then re-install them.
