We have the same problem.
 Microsoft changed the Version from 3.0.0.0 to 3.0.0.1
 I guess this is the reason Visual Studio can't find the reference, because the regular setting is "Use specific version - true".
 In my case i can't change the setting to false, because I am using Mvc4 on the same machine and it would automatically use the version 4 dll.

A solution is to remove the project reference of System.Web.Mvc.dll and add it again. Then VS will use the Version-3.0.0.1-DLL as a reference.

Also you can try use these code maybe it helps.

Goodluck.

As the patch has incremented the version number has risen from (for MVC4 it has risen from 4.0.0.0 to 4.0.0.1) the Reference Path in the project files needs to change from:

<pre><code>&lt;Reference Include="System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL"&gt;
 &lt;Private&gt;True&lt;/Private&gt;
 &lt;HintPath&gt;..\bin\System.Web.Mvc.dll&lt;/HintPath&gt;
&lt;/Reference&gt;
</code></pre>

to

<pre><code>&lt;Reference Include="System.Web.Mvc, Version=4.0.0.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL"&gt;
 &lt;SpecificVersion&gt;False&lt;/SpecificVersion&gt;
 &lt;HintPath&gt;..\bin\System.Web.Mvc.dll&lt;/HintPath&gt;
&lt;/Reference&gt;
</code></pre>

Obviously adjust the hint path as appropriate, and make similar changes for other versions of MVC

I had same issue recently.

After Windows Update - my project in Visual Studio suddenly had 500+ errors - all related to system.web.mvc

So I deleted the reference and re-added it - found in C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 3\Assemblies

Great - project compiles.

Put it on site - get "Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information"

After much messing around, I went to site, downloaded the version of it off there - referenced it - it worked on my laptop AND on site

phew!!!!!!!

After yesterday's Windows Update, I seem to have issues building my projects.

<pre><code>Related Windows Updates could be:
ASP.NET MVC 2.0: KB2993939
ASP.NET MVC 3.0: KB2993937
ASP.NET MVC 4.0: KB2993928
ASP.NET MVC 5.0: KB2992080
ASP.NET MVC 5.1: KB2994397
</code></pre>

<img src="https://i.stack.imgur.com/Y69rp.png" alt="System.Web.Mvc-related errors">

These errors all seem to be related to the <code>System.Web.Mvc</code> namespace of which I checked; it is still being associated with the project under <code>References</code>. What could have gone wrong with my MVC project during the Windows Update, and how should I go about rectifying it?

Here is the log that indicates the updates administered today:
