Microsoft.Xaml.Behaviors.WinUI.Managed is not supported on WinUI UWP

[ganesanviji]

Hi Team,

I have faced the issue like the Microsoft.Xaml.Behaviors.WinUI.Managed NuGet package is not installing in the WINUI UWP application. Please find my replication steps as below,

1. First, I have created the WinUI UWP application
2. Then, I have tried to use the Xaml pages from the UWP Template Studio by change the namespace from the Windows.UI.Xaml to Microsoft.UI.Xaml and added the Microsoft.WinUI NuGet package
3. Also, I have used the Microsoft.Xaml.Behaviors.UWP.Managed NuGet package for xaml page behaviors (for Data Grid, Navigation etc..) in the UWP application
4. I have tried to migrate this UWP xaml pages to the WinUI xaml pages. For this, I have googled and find the Microsoft.Xaml.Behaviors.WinUI.Managed NuGet package.
5. Then try to install this in the WinUI UWP application and I have faced the below issue.
   

Please, update me is this NuGet package is supported for the WinUI UWP platform? If still the NuGet package Microsoft.Xaml.Behaviors.WinUI.Managed is not supported for the WinUI UWP, please share the details about when this NuGet package available with the WinUI UWP support.

Thanks,
Ganesan Rengasamy.

Hello, Martin from Windows Template Studio Team.

We are working on WinUI 3 UWP Templates C# and we are also having this problem. I've created an Issue on WimTS repo to follow this issue up.

Having XAML behaviors is a basic requirement at this point. WinUI+UWP can't move forward without it.

This looks like you're trying to install the UWP package in a WinUI 3 package. For WinUI 3 you need Microsoft.Xaml.Behaviors.WinUI.Managed
