[Monogame 3.8] No tools installed?

I’ve search for some tools like 2MGFX or other.

I’ve installed the latest version of v3.8 from https://www.monogame.net/downloads/.

When i tried to install https://www.nuget.org/packages/dotnet-mgfxc/, the tool are installed:

Both directorys have no Monogame directory:
C:\Program Files\MSBuild
C:\Program Files (x86)\MSBuild

But how i can find the executable path to work with it on Pre-Build events?

When installing dotnet tools the name of the executable is is dotnet-this-is-the-name, just subtract dotnet from the nuget package name.

You will also help yourself a lot if you consult the documentation https://docs.monogame.net/articles/tools/mgfxc.html
