Using Ninject Dependency Injection in an ASP.NET Web API Web Application

I have been using Ninject Dependency Injection in my ASP.NET Web API Projects by simply doing the following things in the past:

1. Install the Ninject Web Host for WebApi 2 NuGet package: https://www.nuget.org/packages/Ninject.Web.WebApi.WebHost/
2. Add the necessary DI mappings in the RegisterServices method of the NinjectWebCommon.cs file found in the App_Start folder

However, even after doing all of this, I experienced the following error message:

An error occurred when trying to create a controller of type 'ValuesController'. Make sure that the controller has a parameterless public constructor.

I had earlier been using an older release of Ninject and did not experience this problem, so I decided to check what version I was using and I was using v. 3.2.4.

As a test to see if a new problem was introduced, I decided to use the older version of Ninject from NuGet (https://www.nuget.org/packages/Ninject.Web.WebApi/3.2.3) by running the following command in the Package Manager Console:

Install-Package Ninject.Web.WebApi -Version 3.2.3

Sure enough, my Web API Controller resolved correctly once I reverted to the older version of Ninject Web API!!

<ArrayOfstring><string>value1</string><string>value2</string></ArrayOfstring>

Therefore, there were some problems in an earlier release of Ninject.Web.Common (v. 3.2.0) that caused the use of the NinjectWebCommon.cs file by itself to no longer be sufficient.

You can use a NinjectDependencyResolver class to workaround this problem as described in this article (http://www.peterprovost.org/blog/2012/06/19/adding-ninject-to-web-api), but if you are having the same problem, it is best to make sure you are using at least v. 3.2.3 of Ninject.Web.Common or a later release.
