MVC Razor view Intellisense broken in VS 2013/2015/2017 - asp.net-mvc

Question

I have an existing project written in VS2010 which when loaded in VS2010 works perfectly.
When I load this same project in VS2013 the MVC Razor views contain lots of errors as if the config file is missing from the views folder.
It appears to have not loaded the Razor editor correctly using the config files from both the root and the views folder and instead gives me errors like ...
The name 'model' does not exist in the current context
and ...
'System.Web.WebPages.Html.HtmlHelper' does not contain a definition for 'LabelFor'
and no extension method 'LabelFor' accepting a first argument of type
'System.Web.WebPages.Html.HtmlHelper' could be found
(are you missing a using directive or an assembly reference?)
...
Any idea what would cause this?
Edit:
Config files as requested ....

Answer 1

I considered editing #ChrisMoschini's post, but thought it was different enough. My issue was that I started a new MVC5 application, and blindly copied over too many web.config settings from an old MVC3 project I wanted to use as a template/starting point. Doing this caused me to have some invalid versions referenced in my web.config.
To fix, I created another new MVC5 project and made sure the following config values in my bad project matched the vanilla, unmodified MVC5 app. Again, do not blindly copy these version numbers. Just make sure they match a vanilla MVC app of the version that you're trying to get to work
in root web.config:
<appSettings>
...
<add key="webpages:Version" value="3.0.0.0"/>
...
</appSettings>
<system.web>
...
<compilation debug="true" targetFramework="4.5.1"/>
<httpRuntime targetFramework="4.5.1"/>
...
</system.web>
in the Views\Web.config:
<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">

Answer 2

A few of my projects had this issues for months. I tried so many workarounds and nothing worked. The issues seemed to be with the projects: the same project will have Intellisense issue across all PCs with Visual Studio. Finally I came through this post: http://www.dennisonpro.info/managing-intellisense-in-razor-views-with-mvc-5-using-custom-builds-in-visual-studio-2013/
In our case the cause was the output directory of all those projects were changed to other than "bin\". By changing the OutputPath back to "bin\" (and cleaning the project, closing then re-opening Visual Studio), I got Intellisense back.
The post referenced above also provided a workaround to maintain a separate output directory while still having Intellisense.
Hope this helps someone someday.

Answer 3

MS says that for VS2013 "Intellisense for Razor (CSHTML and VBHTML) files is limited to HTML markup."
But if you add these two lines inside each .cshtml the intellisense will work again for MVC3 in VS2013:
#using System.Web.Mvc.Html
#inherits System.Web.Mvc.WebViewPage<dynamic>
Instead of dynamic you can put your Model's type.

Answer 4

I upgraded an MVC3 project to MVC5, and did everything I could to avoid the only true answer to this problem that Microsoft recommends:
Start over with a new Project, and port the resulting bits over into your existing project.
That process is a big waste of time, and it seems like Microsoft should make a real upgrade path viable, but I am here to tell you the problem here is an emotional one not technical: You really do need to just create a new MVC5 project, and replace the following with the result of that new MVC5 project:
\Packages\*
\Project\Project.csproj
\Project\packages.config
\Project\Web.Config
\Project\Views\Web.Config
\Project\Areas\*\Views\Web.Config
If you don't you'll just go around in circles for eternity trying to find the one setting that's blowing things up. In our case, I had the Web.Configs all identical to the newly-created, Razor Intellisense-working MVC5 project, I had run every variety of upgrade tool I could find, you name it. Intellisense refused to work.
After just blowing away the .csproj and web.configs etc, Intellisense came magically back to life. Diffing the 2 sides, none of the answers that I've found anywhere match with what I'm seeing. Web.Configs are almost identical, and the bits that are different should be irrelevant. The main change is really what's in \Packages\ - a lot of older Razor, MVC, and WebPages dlls gone. That could be the trick, but skip that and save yourself a lot of time: Just make a new MVC5 project and dump the above-listed files over. It's the only sane method of upgrading.

Answer 5

I have recently solved this problem myself. I upgraded from MVC4 to MVC5 (specifically 5.1). Upgrading to a newer version of MVC caused this havoc and I spent hours trying to solve it. Minor changes to the Web.Config file fixed the intellisense issue!
You said the project works in VS2010, but not 2013? See this answer here.
I recommend upgrading to MVC5. It's not painful and the upgrade should be pretty seamless.
If you upgrade to MVC5 and you're still not getting intellisense, you need to update the Web.Config file manually as the upgrade may not do this correctly!
Here's a modified version of your Web.conifg in the /Views folder that should reflect changes for MVC5.

If upgrading is not an option, then I'm afraid you will need to continue using VS2010 if you want intellisense support for MVC3. However, I strongly suggest upgrading to MVC5.

Answer 6

For anyone else who might stumble across this I didn't find any of the previous answers to really solve my problem or not pertain to it. Anyways the way that solved this for me and made intellisense work again was to go to my bin folder and delete all the files in there and then clean/rebuild and it was fixed.

Answer 7

When I created a new project intellisense worked fine, but for some reason it didn't work in our current project. The only difference I found in the Views/Web.config file was that ours had MVC version 5.2.0.0 and a new project had 5.0.0.0. What worked for us was to change this:
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc,
Version=5.0.0.0, Culture=neutral, PublicKeyToken=123JHJF56AD364E35" />
to this:
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc,
Version=5.2.0.0, Culture=neutral, PublicKeyToken=123JHJF56AD364E35" />

Answer 8

This question has been resolved, but I'm adding this for future folks, since none of the above worked for me:
Try running Visual Studio as an administrator.
Somehow when I tried to delete my nuget packages (which contain all the required references, such as System.Web.Mvc, I was told I need permission from MyPC\Me. Ridiculous! (I am the only user and only admin...) In any case, running as an admin at least let me access those files which fixed intellisense.

Answer 9

A combination of the following helped to solve the problem for me:
Creating a new MVC Project
Comparing the versions in the views web.config files of the existing and new projects
Fixing the versions accordingly (see below)
Deleting all files in the bin folder
Cleaning the solution
and finally rebuilding the solution

Answer 10

I have had this over and over again; I'm on my third new project, and it's driving me mad! I think I may have found the reason for the problem. I'd added files, but not included them in Visual Studio. So I've now chosen to view all files:
Then for all my folders which I'd added, I include them:
The problem is that this only seems to show up when you open an MVC site as a project, and not when you open it as a website.

Answer 11

I eventually had a bunch of other problems on my pc because of a network server crash and ended up reinstalling visual studio.
This apparently solved the problem ... i have no idea how but it did.
I wonder if maybe in my case it was simply just a faulty installation rather than the typical problem.
For that reason I will mark this as the answer but +1 all other replies as they are potentially good answers to this problem.
I did however find that Microsoft clearly states visual studio 2013 does not support intellisense on lower versions of MVC than 4 so if you are using MVC 3 upgrade your project if you are using a newer version of MVC and nothing else here works try reinstalling visual studio.
Also worth noting ...
MVC is now a nuget package so don't install MVC from the download redist allow VS to figure that out for you.

Answer 12

In my case I moved all of the views from an Area to the root Views folder, so I think VS got confused as to where my web.config was. I renamed it to Web.config, from web.config and then made an edit to the contents of the config (such as changing the version number of the razor host factory dll from 5.2.2.0 to 5.2.3), but then changed it back.
Then I went on a walk for about 30 minutes and came back and restarted VS and it was fixed!

Answer 13

In MVC 5 if you try to add an area by just adding a folder under Areas and sub folders for Controllers, Views, Models, etc. you won't have the *AreaRegistration.cs file that registers the area, or the web.config in views that enable VS to understand the razor elements that you include in your views. The result is that intellisense doesn't work in your view for things like ViewBag. If you have working examples of those files in other areas you can copy them in and update as appropriate - or you can start over with your Area by right clicking on Areas and doing an Add - Area which will create those files for you.

Answer 14

I've changed from
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc,
Version=5.2.0.0, Culture=neutral, PublicKeyToken=123JHJF56AD364E35" />
to this:
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc,
Version=5.0.0.0, Culture=neutral, PublicKeyToken=123JHJF56AD364E35" />
And it worked!

Answer 15

Update the NuGet Packages using Package Manager console in Tool, Library package Manager..
In command line..
PM> Update-Package
This will update NuGet packages and verify the current version of System.web.MVC and update this version in web.config file under Views folder.
<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">
<namespaces>
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Optimization"/>
<add namespace="System.Web.Routing" />
<add namespace="System.Web.Webpages"/>
</namespaces>
</pages>
</system.web.webPages.razor>
Close the solution and Reopen.
Hope this works !!!

I had this issue for six months and just realized that I needed to move my #model directives to the top of the pages. I previously had them inside code blocks.

Answer 18

I ran into a similar problem. I had an MVC 5 project created with VS2015 Community Edition that I needed to work on with VS2013 Ultimate. Removing the following <system.codedom></system.codedom> block from the root web.config file is what finally allowed IntelliSense to work again in my Razor views on VS2013.
<system.codedom>
<compilers>
<compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:6 /nowarn:1659;1699;1701" />

Answer 19

Try setting the CopyLocal property of the System.Web.Mvc reference to true. Sometimes this helps with Intellisense.

Answer 20

I am using VS 2017 professional, and I tried almost every answer on this post, and also those on that post, but nothing worked for me. Yesterday I updated VS, to version 15.2 (26430.6) Release, and intellisense is back in my cshtml files!

Answer 21

I have tried almost every solutions but did not get intellisense and at the end I found a solution:
Go to Solution Explorer
Right click on .cshtml file or any view file
Select "Open With" option and make HTML Editor(Default) set as default

Answer 22

In upgrading from MVC 3 to 5, I found that in my root directory Web.config that the appSettings key webpages:version was set to 2.0.0.0. Changing this to 3.0.0.0 fixed this issue.
<appSettings>
<add key="webpages:Version" value="3.0.0.0" />
<add key="webpages:Enabled" value="false" />
</appSettings>
