[unai-d]

If you're not going to use the Eto Forms GUI, you can either remove it from the solution file or just compile the command line interface with dotnet build --project Unai.ExtendedBinaryWaterfall.Cli.

Fixing the build error will take me some more time since I believe this is one of those errors that only trigger under Windows (it's coming from the WPF project, which AFAIK only compiles on Windows).

What's the differences between all of the etoforms guis? im on windows

[unai-d]

Eto Forms gives support for multiple platforms. On Windows, it uses Windows Presentation Foundation (WPF). But I use Linux most of the time and on Linux, it uses GTK instead. So I never had time to try compiling the project under Windows. I'll maybe do it whenever I can on a VM.
