Testing Bug Reproductions with Bootstrap MSBuild

This skill guides you through testing a bug reproduction project against your locally-built MSBuild to verify a fix.

Overview

After making changes to MSBuild, you need to test them against a repro project. The "bootstrap" is a self-contained MSBuild installation built from your local changes. It includes all dependencies needed to build real projects.

Step 1: Build MSBuild with Bootstrap

Build MSBuild to create the bootstrap directory:

# Windows
.\build.cmd

# Unix/macOS
./build.sh
