I just tried to add DataTemplates for Views in a ResourceDIctionary like this:

<DataTemplate DataType="{x:Type vm:MyViewModel}">
	<v:MyView />
</DataTemplate

In WPF that works fine, yet Unity Noesis complains that I cannot add a DataTemplate to a ResourceDictionary without specifying a key.
This is an issue. Implicitly used DataTemplates are supposed to be used this way. Why do I need to specifiy a key? This is another inconsistency between WPF and Noesis
that gets in the way of the Blend + Noesis workflow.

I just created a view model like this:

namespace Testing
{
    public class MyViewModel { }
}

And use it in a xaml like this:

<Grid
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:Testing">
    <Grid.Resources>
      <DataTemplate DataType="{x:Type local:MyViewModel}">
        <Rectangle Fill="Red"/>
      </DataTemplate>
    </Grid.Resources>
    <ContentControl Content="{Binding}"/>
</Grid>

And it parses fine and works as expected when I set an instance of MyViewModel in the DataContext.

What version of NoesisGUI are you using? My tests are with latest 3.0.11 version.

I couldn't reproduce this for some reason. I'll report back if I run into it again. You can close this for now.
