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.
