Windows Dev Performance's Issues

Welcome to the Windows Dev Performance Issues repo!

The purpose of this repo is to collect and catalog issues that affect / impact the inner loop of developers who work on Windows. The developer inner loop would include areas such as compile, run, build, test, debug, and commit. It doesn't matter if you're developing applications FOR Windows or applications that you plan to deploy on Linux, Android, IoT devices, servers, containers, or cloud - if you're building code ON Windows, we'd love to hear from you.

This repo is being driven and managed by a x-team, x-division group of PMs and engineers who're all passionate about improving developers' experience on Windows. We are already coordinating several streams of ongoing work with teams across the company and throughout the community, aiming to drive many issues to ground.
