Included mono libraries interfere with applications that embed mono/xamarin.mac

Type: Debugger

Describe the bug

• OS and Version: macOS 11.0.1
• VS Code Version: 1.51.1
• C/C++ Extension Version: 1.1.3

When debugging an application that embeds mono, the MONO_PATH environment variable that is set during debugging in debugAdapters/OpenDebugAD7 causes the application's embedded mono to use the assemblies included in this extension instead of their own. This environment variable should be avoided, or unset before launching the application.

To Reproduce
This is my launch.json:

        {
            "name": "Launch My App",
            "type": "cppdbg",
            "request": "launch",
            "program": "/path/to/MyApp.app/Contents/MacOS/MyApp",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "externalConsole": false,
            "MIMode": "lldb",
        }

An easy way to avoid this problem I found is to add this line to launch.json, but it should not be necessary:

            "environment": [ { "name": "MONO_PATH", "value": "" }]

Inizia in debugAdapters/OpenDebugAD7, dove MONO_PATH viene impostato durante il debug, e verifica come viene assemblato l’ambiente di avvio per l’esempio launch.json. Riproduci il caso macOS con un’applicazione che integra Mono; il lavoro è completo quando l’applicazione non usa più gli assembly dell’estensione senza richiedere un override di MONO_PATH.
