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 proje

Answer 1

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

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"
    ]
}

Answer 3

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.

Answer 4

If none of suggested methods worked, try:

npm install -g typescript@latest

and then

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

Hope this helps...

Answer 5

Solution that worked for me:

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

Answer 6

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": []
}
