Hi Mauro, i'm starting to test Radical with NetCore 3.1,

2)Install from NuGet Radical (2.0.0-Beta6) and Radical.Windows(2.0.0-Beta9)
3)I create the Folder Presentation and MainView and MainViewModel
4)In App.cs i have change the old
ApplicationBootstrapper bootstrapper = new WindsorApplicationBootstrapper<MainView>();
width
ApplicationBootstrapper bootstrapper = new ApplicationBootstrapper<MainView>();
The project run, the constructor of MainViewModel is execute OK, but the View is not Show, i have the error:

I don't know if I'm wrong something (it's the first Net.Core project) or I'm wrong the boot command.
Many Thanks
@Aurelio67 thanks for raising this. I don't think you're doing anything wrong, I'll have a look at this soon.
In the meantime, I moved the issue to the Radical.Windows repository as I have a hunch of what the problem might be looking at the stack trace.
ok, if it is not a problem I will point out everything that does not work for me by passing a framework project with a core with radical, then when you can you will answer me without haste.
Come al solito grazie..
Absolutely, go on raising issues as you face them.
I've found the bug, that was quick 😄
If there are no registered resources the ViewReolver fails because of a NRE at
resourcesRegistrationHolder.Registrations is null. There a few ways to fix this, I'll write a test first.
Yeah...
When you have solved I proceed with the conversion so I can see if everything works as in the project with the framework.
Thanks.
Raised #201 to start addressing this.
@Aurelio67 2.0.0-Beta.10 is going to on Nuget soon, can you give it a try?
Of course, as soon as you release it I try it right away
It’s available on nuget
Yeah great ... it's work OK, now I will proceed with the other options (IMessageBroker, IConventionHandler, etc.) slowly I do the conversion and if I find problems I will write to you.
Thanks
