MVC 5 and Entity Framework 6 setup with Web API Host Error and Pages Section fix
After adding WebAPI using Nuget I get this error on an MVC 5 and Entity Framework 6 in Visual Studio 2013 Ultimate Preview:
Error 2 [A]System.Web.WebPages.Razor.Configuration.RazorPagesSection cannot be cast to [B]System.Web.WebPages.Razor.Configuration.RazorPagesSection. Type A originates from 'System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' in the context 'Default' at location 'C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\System.Web.WebPages.Razor\v4.0_1.0.0.0__31bf3856ad364e35\System.Web.WebPages.Razor.dll'. Type B originates from 'System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' in the context 'Default' at location 'C:\Users\Marc\AppData\Local\Temp\Temporary ASP.NET Files\temp\72269df4\f821e616\assembly\dl3\b7138798\99faddea_dac7ce01\System.Web.WebPages.Razor.dll'. C:\Users\Marc\Documents\Visual Studio 2013\Projects\ULU4\ULU4\ASPNETCOMPILER ULU4
In the View/Web.Config it contains a section Group and a section under configSections:
<sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
<section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
<section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
</sectionGroup>
</configSections>
I didn't delete any sections but I just changed the last section for just the number 1.0 to 3.0 so there should still be three lines even though below you only see the last line that changed slightly:
<section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
Finally under the system.web.webPages.razor section it looks like this in my working prototype:
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
It was only 1.0.0.0 which is kinda funny so between mvc4 and mvc5 the MvcWebRazorHostFactory appeared to go through 4 completely new revisions? Oh well... I just started plugging in numbers and got lucky.
If you build successfully it should look something like:
1>------ Rebuild All started: Project: ULU4, Configuration: Debug Any CPU ------
1> ULU4 -> C:\Users\Marc\Documents\Visual Studio 2013\Projects\DEMOMVC\DEMOMVC\bin\DEMOMVC
1> DEMOMVC.dll
========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========
Here are the Nuget Packages I have installed and instructions on using Nuget for the uninitiated in Visual Studio Library Package Manager -> Package Manager Console.
To get help from nuget at powershell type: help nuget
Then one of the help commands is:

Hopefully this helps at least one person.
