ASP.NET compiler cannot load System.Web.Mvc after updating to version 5.2.2

I've recently updated to MVC 5, using the instructions on this web page:

http://www.asp.net/mvc/overview/releases/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2

I'm now getting this error:

Could not load file or assembly 'System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

A bizarre behaviour is that sometimes the error actually says version 3.0.0.0 and sometimes 5.0.0.0.

I've done lots of searches, but cannot find anyone with the same error, just similar errors where people discuss changing versions in config files, so here are my config entries:

Under Views:

  <system.web.webPages.razor>
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

There should be same in all assemblyBinding version in main web.config and each Area views web.config file. I have got the same error please find the difference between main web.config and Area view.

You can find the System.Web.Mvc version is 4.0.0.0 in main web.config as

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30AD4FE6B2A6AEED" culture="neutral"/>
                <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0"/>
            </dependentAssembly>
            <dependentAssembly>
                <assemblyIdentity name="WebGrease" publicKeyToken="31BF3856AD364E35" culture="neutral"/>
                <bindingRedirect oldVersion="0.0.0.0-1.5.2.14234" newVersion="1.5.2.14234"/>
            </dependentAssembly>
      <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="WebGrease" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="0.0.0.0-1.3.0.0" newVersion="1.3.0.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

But one of my area web.config under views are

<system.web.webPages.razor>
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <pages pageBaseType="System.Web.Mvc.WebViewPage">
     /pages>
  </system.web.webPages.razor>

Please check the System.Web.Mvc, Version you got the different version. So there should newer version in main config file and area views config file same. so have change the main web.config file as :

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30AD4FE6B2A6AEED" culture="neutral"/>
                <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0"/>
            </dependentAssembly>
            <dependentAssembly>
                <assemblyIdentity name="WebGrease" publicKeyToken="31BF3856AD364E35" culture="neutral"/>
                <bindingRedirect oldVersion="0.0.0.0-1.5.2.14234" newVersion="1.5.2.14234"/>
            </dependentAssembly>
      <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="5.2.3.0"/>
      </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="WebGrease" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="0.0.0.0-1.3.0.0" newVersion="1.3.0.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

I solved my issue, taking the PublicKeyToken and Version system.web->Compilation->Assemblies in the Views\web.config and replacing it in the same file but in the system.web.webPages.razor->host key and root web.cofig at the configuration->runtime->assemblyBinding** and search for the assemblyIdentity which have the name="System.Web.Mvc" and replace its values.

You need to update the version of System.Mvc dll in your projects. SportStore.Domain and SportStore.UnitTests.

To do it first go to one of both project and make a secondary click in project name --> after select the "Manage NuGet Packages"

Inside Manage NuGetPackages you can go to "Updates" tab and select all. Inside this you will see all your Packages available to update.

Select Uptade on your MVC package. In my picture I don't have it because I have full updated.

Repeat this opperation to other project and rebuild your project.

You say that you have upgraded to version 5.2.2. Therefore you should change

<dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
</dependentAssembly>

<dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0-5.2.2.0" newVersion="5.2.2.0" />
</dependentAssembly>

Obviously you will need to replace all occurrences of MVC 5.0.0.0 with 5.2.2.0.
