How to configure StructureMap for asp.net MVC 5

Question

I\'m getting below error. I setup it similar to asp.net mvc 4.

No parameterless constructor defined for this object. Description: An unhandled exception

Answer 1

StructureMap (2.6.4.1) is compatible with ASP.NET MVC 5 and you do not have to change anything after the upgrade.

The upgrade process, though, it is not as straightforward as you might think.

Here's a list of all the steps if you have to follow.

PS: I've followed Rick Anderson's tutorial after the upgrade (and he says you should do it before) but it worked, anyway.

Hope it helps.

The following steps worked for me:

1. Create a new ASP.NET MVC 5 application in Visual Studio 2013 RTM

2. Install the StructureMap.MVC4 NuGet:

   Install-Package StructureMap.MVC4
   

3. Create a new interface:

   public interface IDependency
   {
       string SayHello();
   }
   

4. Implement this interface:

   public class ConcreteDepenedency: IDependency
   {
       public string SayHello()
       {
           return "Hello World";
       }
   }
   

5. Have the HomeController work with this interface:

   public class HomeController : Controller
   {
       private readonly IDependency dependency;
       public HomeController(IDependency dependency)
       {
           this.dependency = dependency;
       }
   
       public ActionResult Index()
       {
           return Content(this.dependency.SayHello());
       }
   }
   

6. Configure your container in ~/DependencyResolution/Ioc.cs:

   using StructureMap;
   using WebApplication1.Controllers;
   
   namespace WebApplication1.DependencyResolution {
   
       public static class IoC {
   
           public static IContainer Initialize() {
   
               ObjectFactory.Initialize(x =>
               {
                   x.For<IDependency>().Use<ConcreteDepenedency>();
               });
   
               return ObjectFactory.Container;
           }
       }
   }
   

7. Run your application with Ctrl+F5

8. The ConcreteDependency is successfully injected in HomeController.

Answer 3

Thank you for all the reply finally found the issue. In my service class I refer a app setting but didn't define it on the web.config file because of that structuremap couldn't inject an instance of my service class.

private readonly string _path =
            ConfigurationManager.AppSettings["vp"].ToString(CultureInfo.InvariantCulture);

Answer 4

I have a detailed walk-through showing how to get this working using the latest StructureMap for MVC 5 package here: http://ardalis.com/resolving-dependencies-in-asp.net-mvc-5-with-structuremap

It's not all that different from what was necessary in ASP.NET MVC 3, which I previously published: http://ardalis.com/How-Do-I-Use-StructureMap-with-ASP.NET-MVC-3

Basically you just install the correct NuGet package, modify your controllers to accept dependencies, and wire up your interfaces to your implementations in IoC.cs. If you follow StructureMap's default convention, you can get this wireup to occur automatically for many types.
