My new ASP.NET MVC Web Application works on my development workstation, but does not run on my web server...

Server Error in '/' Application.

Do I need to install the AspNetMVCBeta-setup.msi on the server? Or is there a different installer for servers?

I just wrote a blog post addressing this. You could install ASP.NET MVC on your server OR you can follow the steps here.

EDIT: (by jcolebrand) I went through this link, then had the same issue as Victor below, so I suggest you also add these:

* Microsoft.Web.Infrastructure
* System.Web.Razor
* System.Web.WebPages.Deployment
* System.Web.WebPages.Razor

I ran into the same issue as sgriffinusa. In addition to the references Phil's article suggests: http://www.haacked.com/archive/2008/11/03/bin-deploy-aspnetmvc.aspx . I added these:

* Microsoft.Web.Infrastructure
* System.Web.Razor
* System.Web.WebPages.Deployment
* System.Web.WebPages.Razor

Godaddy Deployment worked perfectly. Turn custom errors off and add references to correct the errors. That should lead you in the right direction.

Installing MVC directly on your web server is one option, as then the assemblies will be installed in the GAC. You can also bin deploy the assemblies, which might help keep your server clear of pre-release assemblies until a final release is available.

Phil Haack posted a nice article a couple days ago about how to deploy MVC along with your app, so it's not necessary to install directly:

I ran into this same issue trying to deploy my MVC3 Razor web application on GoDaddy shared hosting. There are some additional .dlls that need to be referenced. Details here: http://paulmason.biz/?p=108

Basically you need to add references to the following in addition to the ones listed in @Haacked's post and set them to deploy locally as described.

Microsoft.Web.Infrastructure
System.Web.Razor
System.Web.WebPages.Deployment
System.Web.WebPages.Razor

In VS2010, right click the project in the Solution Explorer and select 'Add Deployable Dependencies'. Then check the MVC related check boxes in the following dialog.

This creates a '_bin_deployableAssemblies' folder in the project which contains all the .dll files mentioned in other answers. I believe these get copied to the bin folder when creating a deployment package.

Quick & Simple Solution: I faced this problem with Microsoft.AspNet.Mvc -Version 5.2.3 and after going through all these threads I found a simplest solution.

Just follow steps:

Open NuGet Package Manager in Visual studio for your project
Search for Microsoft.AspNet.Mvc
When found, change action to Uninstall and Uninstall it
Once done, install it again and try it now

This will automatically fix all issues with references. See image below:

Had the same issue and added all the assembly that they said but still got the same error.

turns out you need to make the "Specific Version" = False.

Specific version should be false.

We want to add it because we are making a class library that uses it.

For me it is here...

C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 4\Assemblies

If your NOT using a hosting provider, and you have access to the server to install ... Then install the MVC 3 update tools, do that... it will save you hours of problems on a windows 2003 server / IIS6 machine. , I commented on this page here Nuget.Core.dll version number mismatch

In addition to the Haack post, Hanselman also has a similar post. BIN Delploying ASP.NET MVC 3 with Razor to a Windows Server without MVC installed

For me, the "Copy Local = true" solution was insufficient because my Website's project references did not include all the dlls that were missing. As Scott mentions in his post, I also needed to get additional dlls from the following folder on my development box: C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\Assemblies. The error message informed me which dll was missing (System.Web.Infrastructure, System.Web.Razor, etc.) I continued to add each missing dll, one by one, until it worked.

I've did a "Update-Package –reinstall Microsoft.AspNet.Mvc" to fix it in Visual Studio 2015.

An important consideration is the web.config file, Some packages can mangle your binding redirects causing havoc (the rogue package was in house package that I did not remove the web.config from the package or making sure the web.config in in the package doesn't have any binding redirects. For example by removing the duplicate and incorrect node resolves this

by removing lines 8 to 24 fixes the build.

Also check the version of the assembly in the web.config inside your Views folder and make sure it matches. I sometimes forget there is a 2nd web.config in that location.

I had the same problem with a bunch of assembly files after moving the project to another solution.

For me, the web.config file was trying to add this assembly:

<add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

Thought the reference in the project was pointing towards version 3.0.0.0 (click on the reference and scroll to the bottom of the properties). Hence I just changed the reference version in the web.config file.

I don´t know if this was just a bug of some sort. The problem with adding all the other references was that the references appeared in the config file but it wasn't actually referenced at all in the project (inside the solution explorer) and the needed files were not copied with the rest of the project files, probably due to not being "copy local = true"

Now, I wasn´t able to find these assemblies in the addable assemblies (by right clicking the reference and trying to add them from the assemblies or extensions). Instead I created a new MVC solution which added all the assemblies and references I needed, and finding them under the new projects references in the solution explorer and finding their path in the properties window for the reference.

Then I just copied the libraries I needed into the other project and referenced them.

After trying everything and still failing this was my solution: i remembered i had and error last updating the MVC version in my Visual studio so i run the project from another Visual studio (different computer) and than uploaded the dll-s and it worked. maybe it will help someone...

I am using Jenkins with .net projects and had troubles with MVC 4 references.

I finallys solved my issue by using a .Net reference search engine functionality based on the registry using :

"HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft.NETFramework\v2.0.50727\AssemblyFoldersEx"

You can create subkey et set the default key to "c:\myreferenceedir" for example.

It saved me with MVC versions and also ASP.net Web pages.

Usefull to add references to the "Add Reference Dialog"

As Others have mentioned, add these refernces to visual studios with Copy Local set to true. ( I also had to add System.Web.Webpages)

Microsoft.Web.Infrastructure
System.Web.Razor
System.Web.WebPages.Deployment
System.Web.WebPages.Razor
System.Web.Webpages

I added "Microsoft ASP.NET Razor" using Manage NuGet Packages.

With Add References, for some reason, I only had System.Web.Helpers 1.0.0 and 2.0.0... but not 3.0.0.

Another option, that worked form me was to delete the references to System.Web.Mvc and System.Web.Http... then re-add them browing to the package locations in the csproj file (you can most easily edit the project with a text editor):

<Reference Include="System.Web.Http">
  <HintPath>..\packages\Microsoft.AspNet.WebApi.Core.5.2.3\lib\net45\System.Web.Http.dll</HintPath>

<Reference Include="System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
  <HintPath>..\packages\Microsoft.AspNet.Mvc.5.2.3\lib\net45\System.Web.Mvc.dll</HintPath>

Could not load file or assembly 'System.Web.Mvc'
