I wish to use XAML island for the C# winform application in .net6.0. Does it support it?

@Vishnu Gopalakrishnan , Welcome to Microsoft Q&A, Does .net6.0 support xaml island? No, based on my test, It will throw the error when I installed the nuget-package Microsoft.Toolkit.Forms.UI.Controls and rebuild the project in .NET 6.0 winform project. Error: If I changed .NET Framework to .net core 3.1, it rebuilds well without the error. Therefore, it is not supported in .net 6.0. Hope this could help you.

No, as the doc says : Using XAML Islands (wrapped controls or WindowsXamlHost) to host UWP XAML controls is supported only in apps that target .NET Core 3.x. XAML Islands are not supported in apps that target .NET, or in apps that target any version of the .NET Framework. There is XAML Islands for .NET 5 , but I did not test it

Thank you.
I followed the same link. My problem is that my user control namespace is not detected in the Winform. The user control is defined in the UWP dll and winform tries to host via XAML Island.

Sorry, I doubted this too.

Using XAML Islands to host WinRT XAML controls in WPF and Windows Forms apps is currently supported only in apps that target .NET Core 3.x. XAML Islands are not yet supported in apps that target .NET, or in apps that any version of the .NET Framework.

So does XAML Island has support in .net 6.0?

@Vishnu Gopalakrishnan ,Sorry for that, after testing, I find that XAML Island has support in .net 6.0. Now I have updated my answer and you could have look. If you want to use it in .NET 6.0, you could submit an issue in the Github.

Thanks for your understanding.
