Language Service crashes in Typescirpt file #12

Closed Regenhardt closed 1 year ago

Regenhardt commented 3 years ago

When opening a Typescript-file, the Angular Language Service seems to crash multiple times in a very short time. As the notification states I have started devenv with /Log and extracted the entry:

This Typescript-file is a 700-lines AngularJs Controller that was converted from JS to TS.

Edit: Angular Language Service 1.0 Visual Studio Professional 2019 16.7.3

Still happening with VS 16.11.2 and Angular Language Service 1.1

@Regenhardt Could you please try updating to the latest version of the extension and let us know if the issue persists?

Regenhardt commented 1 year ago

Can confirm it works now, no more crashes.

Thanks for confirming @Regenhardt!
