To build the WiX toolset:

• Start a VS2026 'Developer Command Prompt'
• Change directory to the root of the cloned repository
• Issue the command devbuild (or devbuild release if you want to create a release version)

Executing your newly built WiX toolset

Pull request expectations

• Pick an outstanding WiX issue (or create a new one). Add a comment requesting that you be assigned to the issue. Wait for confirmation.
• To create a pull request, fork a new branch from the main branch
• Make changes to effect whatever changed behavior is required for the pull request
• Push the changes to your repository origin as needed
• If the main branch has changed since you created your branch, rebase to the latest updates.
• If needed (ie, you squashed or rebased), do a force push of your branch
