Turning off “Language Service Disabled” error mess

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?

Answer 1

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 2

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

Answer 3

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...
