Prism v7.1.0-pre1 Release Notes

Release Date: 2018-04-02 // about 6 years ago

  • General Notes

    📦 Note that all Prism applications using Unity will need to uninstall Unity due to a change from depending on Unity nuget to Unity.Container. This change reduces the number of Unity assemblies being referenced by 75% and removes an obscure secondary reference to CommonServiceLocator for WPF applications.

    Prism 7.1 is NOT compatible with the Xamarin Forms WPF backend.

    Prism.Core

    • 🚚 #1348: Navigation Alignment - moved all navigation interfaces into Prism Core (currently hidden from WPF)

    Prism.Forms

    • #1348: Navigation alignment
      • Added INavigationParameters
      • Added INavigationParametersInternal
      • Added INavigationResult
      • Convert all methods using NavigationParameters to use the new INavigationParameters BREAKING
      • Changed Task INavigationService.NavigateAsync to Task<INavigationResult> INavigationService.NavigateAsync
      • Changed Task<bool> INavigationService.GoBackAsync to Task<INavigationResult> INavigationService.GoBackAsync BREAKING
    • #1347: ContainerProvider - Allows Declaring Types in XAML that require the Container to Resolve them
    • #1353: NavigationFrom not called when navigate to different Hamburger Menu Page
    • #1354: INavigationAware methods are not called on children of a CarouselPage
    • 💥 #1414: BREAKING Changed from Unity NuGet to Unity.Container

    ContainerProvider

    The Container Provider now allows types like ValueConverters to include Dependency Injection of Types/Services in the ctor, and allows the converter to be declared in XAML

    namespace Contoso.Converters{ public class MyValueConverter : IValueConverter { private ILoggerFacade \_logger { get; } public MyValueConverter(ILoggerFacade logger) { \_logger = logger; } public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { \_logger.Log("Converting value", Category.Debug, Priority.None); return value; } public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { \_logger.Log("Converting Value Back...", Category.Debug, Priority.None); return value; } } }

    This can then be used in XAML using the ContainerProvider as follows:

    \<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"xmlns:ioc="clr-namespace:Prism.Ioc;assembly=Prism.Forms"xmlns:converters="using:Contoso.Converters"x:Class="Contoso.Views.ViewA"\> \<ContentPage.Resources\> \<ResourceDictionary\> \<ioc:ContainerProvider x:TypeArguments="converters:MyValueConverter" x:Key="myValueConverter" /\> \</ResourceDictionary\> \</ContentPage.Resources\> \<Entry Text="{Binding Demo,Converter={StaticResource myValueConverter}}" /\> \</ContentPage\>

    🆕 New PrismApplication Base Class

    The Bootstrapper has been marked obsolete and it is recommended to use the PrimsApplication class going forward. This results in less code to get started, and an easier and more intuitive API.

    ➕ Added new Prism.Ioc namespace to handle DI container abstractions. Interacting with the container is now done via the IContainerProvider and the IContainerRegistry interfaces. The IContainerProvider interface is used to resolve services from the container. The IContainerRegistry is used to register types with the container. Access to the actual DI container can be achieved by using the GetContainer() extension method off of the IContainerRegistry and IContainerProvider interfaces.
