Core: Improve inner-loop performance for .NET developers

Created on 2 Nov 2020 · 5Comments · Source: dotnet/core

Summary

Inner-loop performance is critical to providing the developer experiences that are increasingly expected/demanded by developers. How fast developers can make code changes and see the resulting impact in their apps is directly proportional to how productive they can be.

When using other platforms, many of the common inner-loop operations are faster, sometimes dramatically so, than the equivalent when using .NET. First-time user impressions may be negatively impacted by such differences, to the point that it deters their choice of .NET as a developer platform.

I notice this quite a bit when doing TDD, add one line of code, wait 30 seconds for it to compile and validate my test. I guess this would apply to the first two epics.

This is really very critical. From day to day i have pain with slow builds compared to Go compilation.
