Migrate Mobile Blazor Bindings From Preview 1 to Preview 2
Important
This project is an experimental release. We hope you try out Experimental Mobile Blazor Bindings and provide feedback at https://github.com/xamarin/MobileBlazorBindings.
This article explains how to update an existing Mobile Blazor Bindings Preview 1 project to Mobile Blazor Bindings Preview 2.
Update NuGet packages to 0.2.42-preview
In each project file (.csproj
) update the Microsoft.MobileBlazorBindings
package reference's Version
attribute to 0.2.42-preview
.
Update App.cs to use new host and set MainPage
In the shared project edit the App.cs
file to have this constructor code:
...
public class App : Application
{
public App()
{
var host = MobileBlazorBindingsHost.CreateDefaultBuilder()
.ConfigureServices((hostContext, services) =>
{
// Register app-specific services
//services.AddSingleton<AppState>();
})
.Build();
MainPage = new ContentPage();
host.AddComponent<HelloWorld>(parent: MainPage); // Change 'HelloWorld' to your app's main UI page
}
...
}
...
Note
If you have made other modifications or renamed content, adjust the code as appropriate. The critical changes are to use the new MobileBlazorBindingsHost
, setting the MainPage
to a ContentPage
, and passing in the parent: MainPage
parameter.
Update main .razor file to use a ContentView
In the shared project edit your app's main UI page (for example, HelloWorld.razor
) so that the top-level component is a <ContentView>
(instead of a <ContentPage>
):
<ContentView>
...
</ContentView>
