MVVM Light: Adding EventToCommand in XAML without Blend, easier way or snippet?

mvvm mvvm-light eventtocommand

Can anyone tell me what the actual syntax is for EventToCommand class. From what I believe is that EventToCommand class works with Silverlight / WPF and WP7, hence I think its a better choice to go down.

From what I believe, I can add any click event and get it forced into my ViewModel, but I am having an issue in finding the best way to do this.

I know you can add it without Blend, but are there snippets available?

Or is there an easier way to add it via VS 2010? Any help or if anyone knows of a good tutorial on this would be great.

Suppose you use .NetFramework4:

First add namespace:

xmlns:cmd="clr-namespace:GalaSoft.MvvmLight.Command;assembly=GalaSoft.MvvmLight.Platform"

Syntax for the Loaded event.

<i:Interaction.Triggers>
    <i:EventTrigger EventName="Loaded">
        <cmd:EventToCommand Command="{Binding Mode=OneWay, Path=LoadedCommand}"
                            PassEventArgsToCommand="True" />
    </i:EventTrigger>
</i:Interaction.Triggers>
