Current BehaviorCollection code in C# is trying to clone the collection itself and set it on the property changed callback, entering into a call loop that leads to a stack overflow:

<Style TargetType="ListBoxItem" BasedOn="{StaticResource Editor.Style.ListBoxItem}">

<Setter Property="noesis:StyleInteraction.Triggers">

<Setter.Value>

<noesis:StyleTriggerCollection>

<b:EventTrigger EventName="PreviewMouseLeftButtonUp">

<b:Interaction.Behaviors>

<b:ConditionBehavior>

<b:ConditionalExpression>

<b:ComparisonCondition LeftOperand="{Binding IsSelected, RelativeSource={RelativeSource AncestorType=ListBoxItem}}" RightOperand="True"/>

</b:ConditionalExpression>

</b:ConditionBehavior>

</b:Interaction.Behaviors>

<b:InvokeCommandAction Command="{Binding CreateResourceCommand}" CommandParameter="{Binding}"/>

</b:EventTrigger>

</noesis:StyleTriggerCollection>

</Setter.Value>

</Setter>

</Style>
