Visual Studio does this for me a lot as well, especially when projects become larger. The number of times the typeahead caused the app to hang is too numerous to count.

Part of me misses .NET, but I've been mostly working with Golang and Node lately. Visual Studio Code is pretty stellar. Maybe someday VS will catch up to VSC. :)

I haven't used VS in about 2 years now, so this experience may be too many versions out of date to be relevant anymore, but for a while I had very similar problems. And then I uninstalled ReSharper, and VS all of a sudden became very snappy.

I try to avoid anything by Jetbrains, as the process of reporting bugs and trying to get show-stopping bugs fixed has been a nightmare with them. This was during their RC phase of Rider, where I had a number of bugs. They went ahead and shipped it to full release (where it was no longer free of charge) without fixing a single one of the bugs I reported and even followed up on. What is the point of an RC beta test if you are so behind on bug fixes that you're not even able to triage all incoming reports? Seems like it should still be called beta at that point.

To their credit, I've had great experiences with RubyMine, but that was the exception to the rule for my experiences with Jetbrains IDEs.

Edit: Before anyone else downvotes, I'll point out that I realize this is not the experience others have had, but I was not exaggerating these claims.
