I tried a basic implementation of the EventToCommand.

Using VS2015, Xamarin.Forms 1.4.4.6392 (installed in PCL and platform-specific projects) and Corcav.Behaviors 2.0.0 (installed in PCL and platform-specific projects) I have this xaml:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:login="clr-namespace:Client.ViewModels.Login;assembly=Client"
             xmlns:b="clr-namespace:Corcav.Behaviors;assembly=Corcav.Behaviors"
             x:Class="Client.Views.Login.Settings">
    <ContentPage.BindingContext>
        <login:SettingsViewModel/>
    </ContentPage.BindingContext>
    <b:Interaction.Behaviors>
      <b:EventToCommand EventName="Disappearing" Command="{Binding SaveCommand}"/>
    </b:Interaction.Behaviors>

    <StackLayout Orientation="Vertical">
        <!-- -->
    </StackLayout>

</ContentPage>

There seems to be a missing link somewhere...The project compiles but crashes when the application window is opening.

Exception from Windows Phone project:

A similar error when I start the Android project:

Fixed.

I thougt BehaviorCollection was only necessary when adding multiple commands. Tricked by IntelliSense 

<b:Interaction.Behaviors>
      <b:BehaviorCollection>
        <b:EventToCommand EventName="Disappearing" Command="{Binding SaveCommand}"/>
      </b:BehaviorCollection>
    </b:Interaction.Behaviors>
