I am working on an Angular Project in Visual Studio 2019 I've opened as a folder. Everything is working very nicely. Intellisense for TypeScript/JavaScript classes and Angular. And when you roll over a method you get the description and return value and so forth. Is there a way to get the intellisense working for BootStrap and Font Awsome? I know in a .Net Cor project you have to do something with a _view[something] file. Can't remember. I've been out on disablitily for a year and just starting to get back to studying. Figured I'd use the time to finally just sit down here and learn Angular once and for all.
I had the same problem, and I noticed that styles.css also wasn't included in Intellisense.
Instead of working in a folder, I had to:
IntelliSense builds straight away in the component HTML now.
I have read that including node_modules in the project makes searching really slow, but if I exclude node_modules by making it a hidden folder, IntelliSense stops working for bootstrap CSS files again. Styles.css continues to show up, though.
Oh, also I updated Visual Studio to 16.4.5.
