While waiting for 15.5 (hopefully they'll fix it there), you can install 15.2 from here: https://www.visualstudio.com/en-us/productinfo/installing-an-earlier-release-of-vs2017

Thank you for your feedback! We have fixed this issue and it's available in Visual Studio 2017 version 15.4.1. Thank you for helping us build a better Visual Studio!

The Problem seems to be more severe with more CPU Cores. I did a test with assigning just one CPU to devenv.exe and another for the Roslyn-Process. The good thing is that VS does not crash anymore. Unfortunately everything becomes painfully slow. Assigning less cores seems to be a workaround, the question is, how many are acceptable before it crashes again.

We switched to Rider(https://www.jetbrains.com/rider/) for the time beeing. I am really impressed with the experience even though it is a new IDE which was released not long ago. It offers better performance and stability than any Visual Studio I ever used! (which is since the .Net 1.1 days).

This issue seems to be the same as https://github.com/dotnet/roslyn/issues/22650 in the roslyn repository. The fix will be in 15.5 and seems to be considered for backporting to 15.4.

I believe c sharp is like c++ CLR while trying to write wrapper functions for the c++ delay functions cause these issues in the IDE... don't know what solutions Microsoft teams are coming up w/

well spend a buck and change for rider or wait for Microsoft teams to convert c++ clr into c#
