Thank you!
That’s true, with .NET Core and .NET 5.0 you can develop multi-platform, for Windows and Linux. But unfortunately Visual Studio (IDE) is available only for Windows. For Linux you have simplified VS Code which is not enough.
Do you see what kind of workarounds might work on Qubes to make it possible to use Docker on an HVM Windows? Most likely those Docker VMs would be things like Redis cache or SQL Database, but there may be others. That would be writing docker file and executing it to get the correct images, make changes on those and run them.
