Prism.Forms
Prism provides an implementation of a collection of design patterns that are helpful in writing well structured, maintainable, and testable XAML applications, including MVVM, dependency injection, commanding, event aggregation, and more. Prism's core functionality is a shared library targeting the .NET Framework and .NET. Features that need to be platform specific are implemented in the respective libraries for the target platform (WPF, Uno Platform, .NET MAUI and Xamarin Forms).
Prism for Xamarin.Forms helps you more easily design and build rich, flexible, and easy to maintain Xamarin.Forms applications. This library provides user interface composition as well as modularity support.

Prism.Forms
Prism provides an implementation of a collection of design patterns that are helpful in writing well structured and maintainable XAML applications, including MVVM, dependency injection, commanding, event aggregation, and more. Prism's core functionality is a shared code base in a Portable Class Library targeting these platforms; WPF, Windows 10 UWP, and Xamarin Forms. Features that need to be platform specific are implemented in the respective libraries for the target platform. Prism for Xamarin.Forms helps you more easily design and build rich, flexible, and easy to maintain Xamarin.Forms applications.

## New Features ##
### ControlTemplates ###
ControlTemplates have been introduced into the 2.1.0 branch, and have been included on the following types:
- [`ContentPage`](https://developer.xamarin.com/api/type/Xamarin.Forms.ContentPage/)
- [`ContentView`](https://developer.xamarin.com/api/type/Xamarin.Forms.ContentView/)
- `TemplatedPage`
- `TemplatedView`
`TemplatedPage` and `TemplatedView` now serve as the base class for `ContentPage` and `ContentView`. ControlTemplates can be used to define the visual appearance of a Control or [`Page`](http://developer.xamarin.com/api/type/Xamarin.Forms.Page/) while providing a clean separation from the visual hierarchy and the Content itself. ControlTemplates can be applied via Style to greatly expand themeability in Xamarin.Forms.
Along with ControlTemplates the concept of TemplateBindings has been introduced. TemplateBindings work identically to normal Bindings however their Source is automatically set to the parent of the target view which owns the ControlTemplate. Usage of a TemplateBinding outside of a ControlTemplate is not supported.
For more details on how to use ControlTemplates see here: http://xfcomplete.net/general/2016/01/20/control-templates/
### DataTemplateSelector ###
IDataTempalteSelectors allow the selection of a DataTemplate at runtime per item in a ListView.ItemsSource.
Usage:
```csharp
class MyDataTemplateSelector : DataTemplateSelector
{
public MyDataTemplateSelector ()
{
// Retain instances!
this.templateOne = new DataTemplate (typeof (ViewA));
this.templateTwo = new DataTemplate (typeof (ViewB));
}
protected override DataTemplate OnSelectTemplate (object item, BindableObject container)
{
if (item is double)
return this.templateOne;
return this.templateTwo;
}
private readonly DataTemplate templateOne;
private readonly DataTemplate templateTwo;
}
```
```xml
<ListView DataTemplate=local:MyDataTemplateSelector />
```
DataTemplateSelectors have the following limitations:
- No more than 20 templates per ListView on Android
- The DataTemplateSelector subclass MUST always return the same template for the same data if queried multiple times
- The DataTemplateSelector must not return another DataTemplateSelector
- The DataTemplateSelector must not return new instances of a DataTemplate on each call, instead the same instance must be returned. Failure to do so will effectively disable virtualization and lead to an enormous memory leak. Don't do this.
### Effects ###
Effects provide an easy way to customize the native look and feel of controls without having to resort to a complete Custom Renderer. You can use these to customize the native controls, for example, the following Effect shows how to create a Border effect on iOS that will set a 2 pixel purple outline on the control:
```csharp
// located inside iOS specific codebase
public class BorderEffect : PlatformEffect
{
protected override void OnAttached ()
{
Control.Layer.BorderColor = UIColor.Purple.CGColor;
Control.Layer.BorderWidth = 2;
}
protected override void OnDetached ()
{
Control.Layer.BorderWidth = 0;
}
}
```
To apply this effect, all you have to do is attached it via the `IList<Effect> Effects` collection on Element. This is a much simpler way of fine tuning your user interface with native touches.
### Other Improvements ###
- HasUnevenRows dynamic sizing support;
- ListView Virtualization is now supported on Windows ;
- Generic versions of Create () BindableProperty are no longer supported and deprecated;
- The Entry/Editor updates on WP8 and WinRT are now consistent with other platforms;
