Hi all,
Not sure if you have seen the MicroSoft announcement regarding .NET 5, see https://devblogs.microsoft.com/dotnet/introducing-net-5/
Here is also a response from Robert van der Hulst on the X# forums regarding support for it:
Our compiler already supports .Net Core. And AFAIK we have not used any APIs in our runtime that are not available on .Net Core. Maybe one or two, but I am sure we can work around that. The only thing stopping us from giving you .Net core support in VS at this moment is that we don't support the new "lean" project file format (yet). And of course the fact that this new project file format does not support things like Windows Forms and WPF (not even for C#). If you look at the videos of Build you will see that they promise to have the winform and WPF designer support in September 2019.
If you want to see X# working with .Net core try this: <snip>
Hope it is of interest to show that X# is not again a project that will die a sudden death...
