If you wish to build some WASM configs, especially with Platform UNO and SkiaSharp ou need the WSL (Windows Subsystem for Linux).
Run 'Terminal' as Administrator
on PowerShell:
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
Update to WSL 2 ( Windows 10, running version 2004, Build 19041 or higher. )
on PowerShell:
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
Install
Ubuntu 18.04 LTS
The version seams to be important (no more, no less).
Launch to create user and so on ...
on PowerShell:
wsl --list --verbose
for UNO command line open an Ubunto WSH shell and run:
bash -c `wslpath "C:\Users\zepro\.nuget\packages\uno.wasm.bootstrap\1.4.0-dev.16\build\scripts\dotnet-setup.sh"`
