I created a Prism Unity App (from the prism extension pack - really nice), added 2 new views and set up basic navigation between the views. This all worked fine without any hiccups.
What I really want is to use DryIoc (company policy). So I proceeded to remove the unity packages (Unity and Prism.Unity.Forms) and installed the DryIoc Packages (DryIoc and Prism.DryIoc.Forms). Fixed the App.xaml to use the correct namespace (xmlns:prism="clr-namespace:Prism.DryIoc;assembly=Prism.DryIoc.Forms") and alos fixed all the other references to use DryIoc and not the Unity References.
This all compiles and runs without any exceptions. But when I debug it is clear that the AutoWireup does not work as expected (at least as I expect it to). The breakpoint in the ViewModel's constructor (or any other place) is not hit and the Title bindings does not pull through.
Is there a Configuration/Setup or reference that I am missing?
My Code: App.xaml:
<?xml version="1.0" encoding="utf-8" ?><prism:PrismApplication xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:prism="clr-namespace:Prism.DryIoc;assembly=Prism.DryIoc.Forms"
x:Class="XamFormsPrism.App"></prism:PrismApplication>
App.xaml.cs:
public partial class App : Prism.DryIoc.PrismApplication
{
public App(IPlatformInitializer initializer = null) : base(initializer) { }
protected override void ConfigureContainer()
{
base.ConfigureContainer();
}
protected override void OnInitialized()
{
this.InitializeComponent();
this.NavigationService.NavigateAsync(NavigationLinks.MainPage);
}
protected override void RegisterTypes()
{
this.Container.RegisterTypeForNavigation<MainPage>();
this.Container.RegisterTypeForNavigation<ViewA>();
this.Container.RegisterTypeForNavigation<ViewB>();
}
}
MainPage.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:prism="clr-namespace:Prism.Mvvm;assembly=Prism.Forms"
prism:ViewModelLocator.AutowireViewModel="True"
x:Class="XamFormsPrism.Views.MainPage"
Title="MainPage"><StackLayout HorizontalOptions="Center" VerticalOptions="Center">
<Label Text="{Binding Title}" />
<Button Text="{Binding NavigateText}" Command="{Binding NavigateCommand}" /> </StackLayout></ContentPage>
MainPageViewModel.cs:
public class MainPageViewModel : BindableBase, INavigationAware
{
private INavigationService navigationService = null;
private string _title = "Jose Cuervo";
public string Title
{
get { return _title; }
set { SetProperty(ref _title, value); }
}
public DelegateCommand NavigateCommand { get; private set; }
public MainPageViewModel(INavigationService navigationService)
{
this.navigationService = navigationService;
this.NavigateCommand = new DelegateCommand(this.navigate, this.canNavigate);
}
private void navigate()
{
this.navigationService.NavigateAsync("ViewA");
}
private bool canNavigate()
{
return true;
}
public void OnNavigatedFrom(NavigationParameters parameters)
{
}
public void OnNavigatedTo(NavigationParameters parameters)
{
if (parameters.ContainsKey("title"))
Title = (string)parameters["title"] + " and Prism";
}
}
As seen above I use the standard naming convention of PageName & PageNameViewModel with the AutoWireUp set to True.
This all worked fine with Unity but I am missing something in DryIoc...but what escapes me.
I have searched the entire project, there is no reference or trace left of Unity.
Any help is much appreciated.
