I have seen many discussions here on the problems using WINE and Linux. I understand the complexities of trying to build a program for several different OSs. On this porgram, Even the Installer script for Linux fails when I run it on Linux Mint 21.1. Beyond frustration here. That should not happen if a software package is ready for release.
Look at other programs out there. FLDIGI and WFVIEW just to name a couple. Both work on ALL platforms without trying to emulate WINDOWS!
Perhaps changing the approach is in order.
I would like to try the program but I will spend more time pounding my head against the keyboard rather than operating with it. Is that the goal of your group? As hams, I am open to new things. I am not a full fledged computer programmer, however. I am an electronic technician by trade and have been using Linux for at least 10 years. I have my whole station working on Linux. FLDIGI, FLRIG, WFView, jtdx, wsjtx, SDRConnect All are working on Linux. I can go on about logging software and other like Hamclock..... Please get your act together.
From what I see, C# is apparently pretty good on Linux these days. So, in theory, it now might be quite possible to recompile the C# sources natively under Linux...
