UI Application as .NET Core application
The UI Application of ConfuserEx needs to be updated to use .NET core, instead of .NET framework.
There are two ways to go about this: Wait for .NET Core 3.0 and utilise the desktop packs to get everything working again, or use a cross platform UI framework (Avalonia?) to get this working.
The real question is: should it be cross-plat?
Even though we wait for the .NET Core 3.0 release, the desktop packs will be Win only.
Avalonia solves this as it is the only(?) cross platform desktop UI solution, but I don´t know much about it, neither if it is stable at this current point.
Well the CLI is already cross-platform now. Thanks to .NET Core, it's very little, if any, extra afford to support multiple platforms. So there is nothing really speaking against it.
The UI is the only thing that may need some more work. Avalonia doesn't appear to be very stable at this point. That issue is nothing that needs a solution right now. I'll wait and see how things develop, especially with .NET Core 3.
