Answer 2

Add below code in web.config:

<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
  <dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.1" />
  </dependentAssembly>
</assemblyBinding>

Answer 3

<dependentAssembly>
            ***<assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
            <bindingRedirect oldVersion="0.0.0.0-5.2.7.0"*** newVersion="5.2.7.0" />
        </dependentAssembly>

Check correct versions are there

Answer 4

In the error page I had this:

LOG: Redirection detected in the application configuration file: 5.1.0.0 was redirected to 5.2.3.0.

So I had to change this line in the web.config to the 5.1.0.0 version and it worked!

<dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.1.0.0" />
    <!--<bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.2.3.0" /> Older line -->
  </dependentAssembly>

I think this is due to a version problem when I downloaded the code from TFS

Hope this helps

Answer 5

I had this exact same issue using MVC4 with Ninject built for .Net 4.5

To fix this i had to add a binding redirect to my Web.config file: (at the end of the file, just before the </configuration> tag)

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0"/>
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="1.0.0.0-4.0.0.0" newVersion="4.0.0.0"/>
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0"/>
      </dependentAssembly>
  <dependentAssembly>
    <assemblyIdentity name="System.Web.WebPages.Razor" publicKeyToken="31bf3856ad364e35"/>
    <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0"/>
  </dependentAssembly>
    </assemblyBinding>
  </runtime>

This forces the web server to use System.Web.Mvc 4.0.0.0 instead of an older version.

Answer 6

There are some procedures using to fix the issue and if the binding redirect in web.config does not solve the problem, you can try the following steps to fix it:

1) In Visual Studio Solution Explorer tree right-click References under your web project and select Manage NuGet Packages.

2) Go to Browse tab and select nuget.org as Package source.

3) Search and install the following packages: Ninject, Ninject.Web.Common and Ninject.MVC5.

It is also better to update the packages particularly Microsoft ASP.NET MVC on Updates tab of Manage NuGet Packages.

Hope this helps...
