get-vs2017-path

Try to find Visual Studio installation path via COM or registry

As of VS7 (a.k.a. Visual Studio 2017) Microsoft recommends to query the VS setup state via COM, but not everybody is fluent in COM, and not every language has COM bindings, so I created some scripts that utilize Windows builtin tools to query this information. The resolved information is printed to stdout in JSON, e.g.

[16:32:02.47] C:\code\0tni\get-vs2017-path>tools\try_powershell.cmd
[{
"Product": "Enterprise",
"InstallationPath": "C:\\VS\\2017\\Enterprise",
"Version": "15.0.26206.0",
"SDK": "10.0.14393.795",
"CmdPath": "C:\\VS\\2017\\Enterprise\\Common7\\Tools\\VsDevCmd.bat"
},{
"Product": "BuildTools",
"InstallationPath": "C:\\VS\\2017\\BuildTools",
"Version": "15.0.26206.0",
"SDK": "10.0.14393.795",
"CmdPath": "C:\\VS\\2017\\BuildTools\\Common7\\Tools\\VsDevCmd.bat"
}]
[16:32:04.43] C:\code\0tni\get-vs2017-path>

There are 3 scripts

1. try_powershell.cmd will try to JIT compile some C# code that calls COM, and prints the interesting stuff to stdio
2. compile-run.cmd will try to find a C# compiler to compile the query then run the generated exe
3. try_registry.cmd will look for undocumented registry traces

The Javascript interface will find older versions as well
