After feedback on the VSSetup PowerShell module to query Visual Studio 2017 and related products, I’m pleased to say that a native, single-file executable is available on GitHub: vswhere. The VSSetup PowerShell module is also available on GitHub and provides a number of benefits for PowerShell scripts, but build tools and CMake and deployment scripts wanted a simple executable they could redistribute without spawning PowerShell.
You can enumerate instances with optional demands on which products, workloads, and components; and on which versions you require. Results can be printed in a variety of formats – currently colon-delimited plain text and JSON. If the query API isn’t registered, rather than erring no instances are assumed to be installed and results are empty, e.g. an empty array for JSON.
In a batch build script you could, for example, find MSBuild 15.0 by finding the latest, newest instance with MSBuild installed.
set pre=Microsoft.VisualStudio.Product. set ids=%pre%Community %pre%Professional %pre%Enterprise %pre%BuildTools
for /f "usebackq tokens=1* delims=: " %%i in (`vswhere -latest -products %ids% -requires Microsoft.Component.MSBuild -version [15.0,16.0)`) do ( if /i "%%i"=="installationPath" set InstallDir=%%j )
if exist "%InstallDir%\MSBuild\15.0\Bin\MSBuild.exe" ( "%InstallDir%\MSBuild\15.0\Bin\MSBuild.exe" %* )[/code]
