Angular doesn’t have its own file extension so the language service activates on typescript files and disables itself if angular is not found in the project sources. This should be very quick and only happen a single time for any given project.

Are you seeing this take a long time for some reason? If so, it would be helpful to get a reproduction if possible or some measurement of the time from the server logs.
