Turning off “Language Service Disabled” error message in VS2017

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 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.
