I am trying to make a WebForms project and ASP.NET MVC per this question. One of the things I've done to make that happen is that I added a namespaces node to the WebForms web.config:
<pages styleSheetTheme="Default">
...
<namespaces>
<add namespace="System.Web.Mvc"/>
<add namespace="System.Web.Mvc.Ajax"/>
<add namespace="System.Web.Mvc.Html"/>
<add namespace="System.Web.Routing"/>
</namespaces>
</pages>
However, when I try to start the project, I get an error stating: "Compiler Error Message: CS0234: The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)"
I have System.Web.Mvc referenced. What is the issue?
Add System.Web.Mvc in the compilation section,
<compilation debug="true">
<assemblies>
<add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
<add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add assembly="System.Web.Abstractions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add assembly="System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add assembly="System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</assemblies>
</compilation>
It's easier to start with an MVC project, and then start adding WebForms pages.
For your error, you will need to add references for the following assemblies:
System.Web.Mvc
System.Web.Routing
System.Web.Abstractions
There will be much more to add in the web.config to get MVC working correctly. To get it all, I'd suggest creating an MVC project, and merging the web.config files.

I am trying to add sitecore to an existing solution where we already have an MVC Application.Now after adding Sitecore,I will make sitecore as start up project and add the reference of existing MVC Application as a reference to Sitecore MVC Application.
Since the existing application was using 4.5.1 and MVC 5.2.3,I am also using the same for my sitecore application.But the existing MVC application is using below:
1. System.Web.Http (Version:5.2.3.0)
2. System.Web.Http.WebHost (Version:5.2.3.0)
3. System.Net.Http.Formatting (Version:5.2.3.0)
So can I use the same for Sitecore?.If yes then I will have to Modify Web Config

Is this change fine?.Please suggest.
Instead of adding Sitecore to your solution you should probably look at it the other way around I.e getting your Mvc application to work in Sitecore.
You shouldn't really change the assembly versions Sitecore is using and you should try to get your Mvc application to work with Sitecore. You can't 100% guarantee that Sitecore will work using higher or lower versions of assemblies that it needs. Whereas with your Mvc solution (I'm assuming you have the source code) you can always try to modify this to work with Sitecore.
Verified with sitecore support and they confirmed that all the above changes are fine.
I have an asp.net mvc 4 project working on VS2010, it was working fine yesterday but I uninstalled VS2012 and the project has now stopped working, it throws the following exception message:
System.IO.FileNotFoundException: Could not load file or assembly
'System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The
system cannot find the file specified.
I have checked and this is not referenced anywhere in the project, the project uses SignalR, maybe this is a requirement for it?
I have checked the related questions in the site but still cannot make it work

This is very strange. An MVC View refuses to recognize the System.Speech namespace. What's the deal? And is there a work around for this? I have a ViewModel that has the VoiceAge and VoiceGender enum properties from this namespace, but the MVC view isn't playing ball.
Repro
Create a new MVC 3 project
Add the "System.Speech" reference
Try to navigate to the System.Speech namespace in the view
In the Controller it's no problem:
using System.Speech.Synthesis;
using System.Web.Mvc;
namespace MvcApplication6.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
VoiceAge voiceAge = VoiceAge.Adult;
return View();
}
}
}
The View, not so much:
I've even added the namespace to the web.config, no luck:
<pages>
<namespaces>
<add namespace="System.Speech.Synthesis" />
Make sure that the System.Speech assembly is present in the <assemblies> section of your web.config:
<assemblies>
<add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

<add assembly="System.Speech, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
</assemblies>
Once it is added there make sure you recompile, close and re-open the .aspx view and then, normally, it should work.
I am developing a web app using ASP.NET MVC 2.0 in MonoDevelop. I have latest Mono 2.10 and MonoDevelop 2.4.2 and I am running them on Mac.
According to mono’s release notes, it should support ASP.NET MVC 2.0. However, I found MonoDevelop’s project templates still only support ASP.NET MVC 1.0. So I had to create MVC project from MonoDevelop and remove system.web.mvc 1.0.0.0 from reference and add system.web.mvc 2.0.0.0 back in. I can write and compile code OK and MonoDevelop does provide intellisense for methods only exist in MVC 2.0 from both C# and aspx file. However, when I trying to run it from MonoDevelop, I had Compilation error complaining ”<%: Html.LabelFor(model => model.Name) %>” as LabelFor method cannot be recognized .
MonoDevelop uses XSP as its testing web server. I am not sure how it configured as I didn’t install it myself. I think it was installed as part of MonoDevelop. My guess is XSP somehow still uses MVC 1.0 but I can't prove it as I couldn’t even find where it is installed.
Could anyone help me out please?

Setting up an ASP.NET project for ASP.NET MVC requires changing and adding a load of settings in web.config. The project template in MD is for ASP.NET MVC 1.0, not ASP.NET MVC 2, so you're probably missing some of the necessary settings, maybe a namespace import.
I have this running with two of my current projects on MacOS X. There were only three steps I needed to make sure were done, they are as follows:
Upgrade the version on all references in both the inner (views) web config and the outter(app) [you've done this].
Dereference System.Web.MVC 1.0.0.0 & Reference 2.0.0.0 for the project
Ensure you don't have 1.0.0.0 binaries in your bin path, the public key does not change
I've done a downloadable zip file of a project template for Asp.Net MVC 4 which builds and runs on/in Mono/Xamarin Studio/MonoDevelop on Mac & Linux at http://www.cafe-encounter.net/p1319/run-asp-net-mvc4-on-mono-monodevelop-on-mac-the-c-template-project.
I should add that a lot of the issue resolution came from Does the Razor View Engine work for Mono?
So I wrote a custom web control in MVC, and I did the whole csc thing to create a dll out of it.
That didn't work, but when I removed it and everything. My MVC thing broke, and it's giving me this error:
Parser Error Message: Could not load type 'System.Web.Mvc.ViewPage'.
for this line:
<%# Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master"
Inherits="System.Web.Mvc.ViewPage<List<className>>" %>
It's not liking strongly typed view now (normal views are working okay)! I'm not registering the dll anywhere anymore. I deleted the dll from bin. I even got rid of the class.
