@persskog you're on WindowsAppSDK 1.6.X, so your issue is not related to my original report - which is about WindowsAppSDK 1.5.X. I recommend you opened a new issue to not confuse matters. Thanks
The recent Windows SDK projection update did add some Windows namespace types to address another issue. Most of those overlapping types were duplicate types between the Microsoft and Windows namespaces and the Windows namespace ones were unused in WinUI scenarios. But there were a couple that are used like TextDecorations which when explicitly used will run into this issue. We have addressed this in WinAppSDK 1.6, which was built with the new Windows SDK projection update, by declaring those types as forwarded to the Windows SDK projection.
If you are able to move to WinAppSDK 1.6, that should address this issue. Otherwise, if you want to stay on 1.5, you can use the older Windows SDK projection version (.34) by specifying the below property in your csproj or in a common props file which should keep things working. Once you are able to move to 1.6, you should remove the property.
<PropertyGroup>
<WindowsSdkPackageVersion>10.0.19041.34</WindowsSdkPackageVersion>
</PropertyGroup>

This has been addressed in the latest Windows SDK projection update which should be available in next month's .NET SDK release. If you want to try it out earlier, you can specify the WindowsSdkPackageVersion property to the appropriate version based on TFM listed here.

@manodasanW, the above issue occurs in latest VS2022 stable version[17.11.5] and VS2022 preview version[17.12.0 Preview 5.0]. Currently we could not able to update WindowsAppSdk version to latest version.
Is there any specific .NET SDK release version or date to fix this issue?
@SubashiniMahendran If you can't yet update to the latest WinAppSDK version, the recommendation is to lock your Windows SDK projection version to the version before those types were added to it. You just need to add something like the below to your csproj or a common props file assuming you are targeting 19041 in the target framework. When you move to WinAppSDK 1.6, you can remove it.
<PropertyGroup>
<WindowsSdkPackageVersion>10.0.19041.34</WindowsSdkPackageVersion>
</PropertyGroup>
