microsoft/setup-msbuild

You know how handy that 'Visual Studio Developer Command Prompt' is on your local machine? And how it adds several things to PATH to allow you to just issue commands like msbuild or otherwise? Use this action to setup similar flexibility in your Windows-based GitHub Actions runners. This will let you discover where those tool paths are and automatically add them to the PATH environment variables for you so future steps in your Actions workflow can just initiate commands without knowing the full path.

Usage

- name: Add msbuild to PATH
  uses: microsoft/setup-msbuild@v1.0.0

Specifying specific versions of Visual Studio

You may have a situation where your Actions runner has multiple versions of Visual Studio and you need to find a specific version of the tool. Simply add the vs-version input to specify the range of versions to find. If looking for a specific version, enter that version number twice as a range.

- name: Add msbuild to PATH
  uses: microsoft/setup-msbuild@v1.0.0
    with:
      vs-version: [16.4,16.5]

How does this work?

This makes use of the vswhere tool which is a tool is delivered by Microsoft to help in identifying Visual Studio installs and various components. This tool is installed on the hosted Windows runners for GitHub Actions. If you are using a self-hosted runner, you either need to make sure vswhere.exe is in your agent's PATH or specify a full path to the location using:

- name: Add msbuild to PATH
  uses: microsoft/setup-msbuild@v1.0.0
    with:
      vswhere-path: 'C:\path\to\your\tools\'

Notes on arguments

While the Action enables you to specify a vswhere path as well as a vs-version, these are more advanced options and when using GitHub-hosted runners you should not need these and is recommended you don't specify them. Using these require you to fully understand the runner environment, updates to the tools on the runner, and can cause failures if you are out of sync. For GitHub-hosted runners, omitting these arguments is the preferred usage.

Building this repo

As with most GitHub Actions, this requires NodeJS development tools. After installing NodeJS, you can build this by executing:

npm install
npm run build
npm run pack

which will modify/create the /dist folder with the final index.js output
