Count me as a lifetime customer that wants Linux support - because I'm completely switching to it. Time to start a fork to dotnet core 3.1, even if it's just a stripped down version of the database features to start - I can live without BigBox for now.
You're also missing out on potential Mac customers, unless there's already support for that.
And just as a note, I've been a .NET/c# developer since the 2.0 beta, so I understand that this isn't an easy task.
Heck, I'm going to really miss Visual Studio, but it is what it is for me.
Open-Source this new "Launchbox Core", and Jason will get all sorts of support. Sounds like he needs a vacation anyway.
Also, .NET 5 is coming. Standard is dead.
Thank you.
