Mahapps.metro: MetroWindow Opacity Not Working

[joazlazer]

I found a way to make the window fade out on exit (http://stackoverflow.com/questions/867656/fading-out-a-wpf-window-on-close) and I wanted to implement it in my application.

Unfortunately, I got:

I tried setting the AllowsTransparency on the MetroWindow in my xaml file and it doesn't change it. Could someone tell me what I am doing wrong?

Try

<i:Interaction.Behaviors>
        <Behaviours:BorderlessWindowBehavior AllowsTransparency="whatever here"/>
</i:Interaction.Behaviors>

[joazlazer]

    <i:Interaction.Behaviors>
        <Behaviours:BorderlessWindowBehavior AllowsTransparency="True"/>
    </i:Interaction.Behaviors>

makes

Now it doesn't have a border and it still doesn't work :/ Also, AllowsTransparency="False" doesn't work either.

@joazlazer @Amrykid the new BorderlessWindowBehavior set the AllowsTransparency of the MetroWindow always to false. i must consider what's the best way to allow users to set this to true without braking the solved issues like "oj, i don't see my browser.... i don't see my winforms control..."

Have a property public bool OverridesAllowsTransparency { get; set; } in MetroWindow?

I got it working just by adding

this.AllowsTransparency = true;

In the window constructor, after the InitializeComponent method call.

FYI, i'm working with 0.13.1.0 version. The bug appeared when I upgraded from 0.12.1.0.
