[QGIS-Developer] How to setup Visual Studio 2019 environment for QGIS C++ development?

Wed Aug 5 01:08:37 PDT 2020

Yes, it's possible to run QGIS using WSL2. I have it running in my Windows.

My colleague, Rizky, writes a note about it here
https://github.com/lucernae/wsl2-qgis

Perhaps, it also possible to develop QGIS by using WSL2 on Windows

Best regards.
