Preconditions

You need to setup the system environment variable GODOT_BIN, the full path to the Godot executable.

Platform	Environment Variable	Example Path
Windows	%GODOT_BIN%	d:\development\Godot_v4.2.1-stable_mono_win64\Godot_v4.2.1-stable_mono_win64.exe
Linux/Unix/Mac	$GODOT_BIN	/Users/MisterX/Documents/develop/GodotMono.app/Contents/MacOS/Godot

Or use the .runsettings to define the environment variable.

  <RunSettings>
    <RunConfiguration>
        <EnvironmentVariables>
            <GODOT_BIN>d:\development\Godot_v4.2.1-stable_mono_win64\Godot_v4.2.1-stable_mono_win64.exe</GODOT_BIN>
        </EnvironmentVariables>
