How can I get xaml hot reload to work for custom types in WPF

问题

I am using the ReactiveUI library within my WPF project and it seems that ReactiveUserControl<TViewModel> : UserControl and the ReactiveWindow<TViewModel> : Window don't work with the XAML Hot Reload.

Although extending directly from a Usercontrol did allow me to use the XAML hot reload.

I can not find any documentation or posts on the matter besides this one page which explains absolutely nothing. Wondering if it maybe has to do with the x:TypeArguments="navigation:MainVM" that you have to pass in or the ReactiveUI library messing something up internally?

I am using visual studio 2019 but the same problem occurs on visual studio 2017, besides that I am using .NET Framework 4.6.1 and ReactiveUI version 9.20.1.
