Set BindingContext to ViewModel in XAML on Xamarin.Forms

Question

I want to develop a simple project with Xamarin.Form and MVVM. In my solution (named XamarinPOC) i have (in addition to standard Xamarin.Forms projects) one separate project

To bind the view to the viewmodel from Xaml in your case do it like this

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:viewModels="clr-namespace:XamarinPOC.ViewModel; assembly=XamarinPOC.ViewModel"
             x:Class="XamarinPOC.Summary"
             Title="Summary List">
  <ContentPage.BindingContext>
    <viewModels:SummaryViewModel/>
  </ContentPage.BindingContext>
  <StackLayout>
    <Label Text="{Binding test}"/>
  </StackLayout>
</ContentPage>

One side note I noticed is with naming conventions, it is better to put all your ViewModels, even if it is only one viewModel, inside a folder named "ViewModels" So the namespace in your case would be XamarinPOC.ViewModels
