Remarks

This class is a Page that is also reactive. That is, it implements IViewFor<T>. You can extend this class to get an implementation of IViewFor<T> rather than writing one yourself.

Note that the XAML for your control must specify the same base class, including the generic argument you provide for your view model. To do this, use the TypeArguments attribute as follows: 

<rxui:ReactivePage
        x:Class="Foo.Bar.Views.YourView"
        x:TypeArguments="vms:YourViewModel"
        xmlns:rxui="http://reactiveui.net"
        xmlns:vms="clr-namespace:Foo.Bar.ViewModels"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        mc:Ignorable="d">
    <!-- view XAML here -->
</rxui:ReactivePage>

Note that UWP and WinUI projects do not support the TypeArguments attribute. The XAML designer window in WPF projects also does not support generic types. To use ReactivePage<TViewModel> in XAML documents you need to create a base class where you derive from ReactivePage<TViewModel> with the type argument filled in. 

internal class YourViewBase : ReactivePage<YourViewModel> { /* No code needed here */ }
public partial class YourView : YourViewBase
{
/* Your code */
}
Then you can use this base class as root in your XAML document. 
<views:YourViewBase
        x:Class="Foo.Bar.Views.YourView"
        xmlns:rxui="http://reactiveui.net"
        xmlns:vms="clr-namespace:Foo.Bar.ViewModels"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        mc:Ignorable="d">
    <!-- view XAML here -->
</views:YourViewBase>
