.Net Maui Embedding ContentView not showing

[cbdefontenay]

Hi!
I just created a new startup project from the Uno Wizard template with .NET MAUI embedding, I tried to display the given EmbeddedControl.xaml ContentView from the Maui.Controls generated project in C# Markup, following the documentation on how to implement it:

public sealed partial class MainPage : Page
{
    public MainPage()
    {
        this.Content(
            new StackPanel().Children(
                new Grid().RowDefinitions("Auto,*")
                    .Children(
                        new TextBlock().Text("The Maui Embedding view will be displayed here:").Grid(row: 0),
                        new MauiHost().Grid(row: 1).Source<EmbeddedControl>()
                    )
            )
        );
    }
}

But somehow I just get to see the first TextBlock text on the screen but not the Maui ContentView. Does someone has an idea?

Hey @cbdefontenay,

Thank you for reporting this! Could you provide a bit more detail to help me reproduce the issue?

• Are you using the latest Uno 6.0? (You can check the version in your global.json file)
• Are you using Skia or native rendering? (Look in your .csproj file — if you see SkiaRenderer in the UnoFeatures, you're using Skia; otherwise, it's likely native)

Thanks in advance!

Hi @morning4coffe-dev,

Sure, sorry for not providing it beforehand.

Steps to reproduce (.NET 9):

1. Create a new project from Rider (IDE), and choose MAUI Embedding as an option, C# Markup, Skia and not Native, no HTTP, MVVM.
2. In the project Global.json file I am using the latest Version of Uno: "Uno.Sdk": "6.0.67".
3. I checked the .csproj file and I am using SkiaRenderer as wished when creating the project.
4. Just try to display the EmbeddedControl.xaml ContentView like in my first message that the startup project is giving you inside the MainPage.cs in the Uno project part and you'll get exactly my setups.

Target Platforms: Android and Windows 11 Desktop.

Thank you for your reply, and let me know if you'd like more informations.

P.S: I also tried using the C# Markup extension from the CommunityToolkit.Maui.Markup in the .NET MAUI project, and it is throwing errors. It says I have to downgrade the CommunityToolkit packages to be able to install it or Upgrade the Microsoft.Maui.Controls and Microsoft.Maui.Controls.Compatibility nuget packages, but when doing so, the app is unable to build, and I have to downgrade the two Microsoft.Maui.Controls. packages back to their 9.0.51 version (Version of the startup project). But that is irrelevant to the upper problem, I just thought I let you know that issue of mine as well.

Hey @cbdefontenay,

Thank you for providing more details. I was able to replicate the issue with SkiaRendering enabled. As a workaround, you can disable it for now by removing it from UnoFeatures. I’ll check with the team and share more information as soon as it's available.

Here is my sample project with the details: UnoApp1.zip.

Unfortunately, I’m not familiar with the specifics you mentioned regarding MAUI, as I haven’t used it in a while.

I’ve opened an issue here: #20439, where you can track its progress.
