Turning off "Language Service Disabled" error message in VS2017

Question

We are getting the following "Error" message in our MVC web application in Visual studio 2017 Enterprise.

The language service is disabled for project 'C:\Work\Blackhawk Platform\Platform-DEV-Branch\BlackhawkViewer\BlackhawkViewer.csproj' because it included a large number of .js files. Consider excluding files using the 'exclude' section of a 'tsconfig.json' file.

I have tried turning off the Language service in the options but this does not turn the message off:

This is a rather large web application. Is there a way to turn this message off without disabling any files in the tsconfig.json file as it suggests?

Some JavaScript files were excluded from your project .csproj file. — Iman Bahrampour, Aug 26 '17 at 10:33
@iman.Bahrampour No that is not the case here. This was a VS bug which was fixed. — TResponse, Aug 26 '17 at 22:20
As the error shows: `because it included a large number of .js files` in your BlackhawkViewer.csproj file. A number of .js files included in your project, while they are deleted from your solution. — Iman Bahrampour, Aug 29 '17 at 05:25
It may look irrelevant but In my case I just didn't have enough disk space — Berk Derek, Dec 04 '18 at 11:05

To solve this issue do the following:

Create file in root directory of your project and call it tsconfig.json
Add this:

{
  "compilerOptions": {
    "allowJs": true, 
    "noEmit": true, 
    "module": "system",
    "noImplicitAny": true,
    "removeComments": true,
    "preserveConstEnums": true,
    "sourceMap": true
  },
  "include": [
    "scripts"
  ],
  "exclude": [

  ],
  "typeAcquisition": {
    "enable": true 
  }
}

Please have a look at the below two links for tsconfig.json explanation, because you may still need to change it according to your setup. This is the only way that worked for me. I hope that will help.

Whilst this code snippet is welcome, and may provide some help, it would be [greatly improved if it included an explanation](//meta.stackexchange.com/q/114762) of *how* it addresses the question. Without that, your answer has much less educational value - remember that you are answering the question for readers in the future, not just the person asking now! Please [edit] your answer to add explanation, and give an indication of what limitations and assumptions apply. – Toby Speight Apr 26 '17 at 08:09

this solution didn't work for me, i have lots of javascript files and even excluding one of the folders with lots of js files did not work for me, using the tsconfig.json – inN0Cent May 09 '17 at 00:59

I also have a lot of javascript files and it worked, try to clean the solution, rebuild and restart visual studio might help. – Moustafa Mansour May 10 '17 at 00:36

This is the right answer, and a solid one. Thanks for providing the links too. – Neo Jun 26 '17 at 13:54

I added the above file and now get the error: The config file 'project/tsconfig.json' found doesn't contain any source files. – Allan Nielsen Oct 20 '17 at 02:58
This solution does not work. See prior comment by Allan. – Sean Kendle Apr 13 '18 at 15:02
@AllanNielsen it's because you have to list the scripts you want to include, or more simply just do a pattern to capture all the scripts. In my solution, including `wwwroot/**/*.js` captures everything. [See this](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html) – Corey P Oct 09 '18 at 14:32

This helped me. You can have a try.

 Go to Tools -> Options -> Text Editor -> JavaScript/TypeScript -> Language Service -> General

and uncheck the box: "Enable the new JavaScript language service.

yes that's the way but at the time I asked the question VS2017 had a bug where it did not honor that setting. It has since been fixed. – TResponse Dec 19 '17 at 20:46

@loan.burger This bug still occurs for me. – thecoolmacdude Apr 19 '18 at 14:48
for me also. Everytime I update VS2017 to a newer version, bug appears again. – oneNiceFriend Apr 21 '18 at 18:57
I also had to reinstall visual studio – Moons Jul 15 '19 at 15:28
In visual Studio 2013 that command does not exist; but this worked for me: Go to Tools -> Options -> Text Editor -> JavaScript - and under Statement Completion, deselect the two checkboxes for: Auto-list members and Parameter information. – Marvin Dec 04 '19 at 15:40

I have found a solution for this problem.

I reset my userData using:

devenv.exe /resetuserdata

Since doing this the JavaScript settings seem to have persisted and I no longer get the language service error above.

TAKE NOTE: This will reset all your user data and customisations.

I've found that `git clean -fxd` also seems to fix the issue. – Mike Cole Apr 21 '17 at 15:29
This worked for me. Adding the tsconfig did not , especially if you do not add include, it will complain there is nothing to build – user1029883 May 24 '17 at 14:02
Sorry I have to take back my comment. Message just re appeared again :( – user1029883 May 24 '17 at 14:29
I have not had this issue since 3 updates ago. Make sure your running thevlatest version of vs2017 bu running the visual studio installer and pressing updates if the update button appears. – TResponse May 24 '17 at 19:15
where exactly am I supposed to type this? – Bibek Aryal Jul 09 '17 at 09:04
@bibek when launching the .exe file. Best to use the windows command prompt in administrator mode. – TResponse Jul 10 '17 at 14:33

In My case I just disable TypeScript support on Visual Studio:

Tools > Extensions and Updates > TypeScript for Microsoft Visual Studio > Disable

After that, just restart Visual Studio, and you are good to go.

Hope this will help,

I had the same problem after migrating Ionic 1 project from VS2015 to VS2017, first I executed git clean -fxd as sugested above and added this content into tsconfig.json in my ionic project.

{
"compilerOptions": {
    "noImplicitAny": false,
    "noEmitOnError": true,
    "removeComments": false,
    "sourceMap": true,
    "target": "es5"
},
"exclude": [
    "node_modules",
    "www",
    "bower_components"
    ]
}

This adds nothing that isn't covered in Moustafa's answer – Neo Jun 26 '17 at 13:46

I used the solution implemented by Moustafa and it didn`t work for me. He didn't set up the exclude modules. – Fabio Campinho Jun 27 '17 at 16:40

I solved this problem with following solution:

When you have a JavaScript file that is included in the project.csproj file but isn't in the project folder, this error occurred.

For example I have a .csproj file like below:

 <ItemGroup>
     <Content Include="Scripts\Test.js" />
 </ItemGroup>

The Test.js is included in the .csproj file, but it isn't in the Scripts folder:

Delete the <Content Include="Scripts\Test.js" /> line from the .csproj file and rebuild your project

Solution that worked for me:

Go to C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE>.
Open command prompt as admin in current folder
Ran devenv /Setup
Ran devenv /ResetSkipPkgs

For me is helping the next solution. I've create a tsconfig.json file in root of the my project with "disableSizeLimit": "true" option.

So, my tsconfig.json file is:

{
  "compilerOptions": {
  "disableSizeLimit": "true"
},
"exclude": []
}

If none of suggested methods worked, try:

npm install -g typescript@latest

and then

Install the latest version of TypeScript for Visual Studio on Get TypeScript.
