I am trying to override the ContentTemplate for the Button, but nothing happens.

Template definition:

<DataTemplate x:Class="Namespace.StringTemplate"
              xmlns="https://github.com/avaloniaui"
              xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
              x:DataType="x:String">

    <TextBlock FontSize="18"
               Text="{Binding .}" />
</DataTemplate>

Using the template:
<Button ContentTemplate="{Binding t:StringTemplate}" xmlns:t="clr-namespace:Namespace.StringTemplate" />

The StringTemplate property is defined in the ViewModel.

This is a simple example. In reality, the template is more complex - it’s not just a string.

Can you open a bug with repro? It's not a common usecase, but seems like something is broken.
