When creating a new WinUI project in Visual Studio, it doesn't work

[branislavjuhas]

Describe the bug

When creating a new project, it doesn't build, but just writes, even reinstalling Visual Studio with all of the dependencies doesn't help. In addition, the fun part is that the .NET SDKs listed in the error cannot be downloaded and as of right now the last released version of SDK is 8.0.401, but it requires 402:

Severity Code Description Project File Line Suppression State
Error (active) This version of the Windows App SDK requires Microsoft.Windows.SDK.NET.Ref 10.0.19041.38 or later.
Please update to .NET SDK 6.0.134, 6.0.426, 8.0.109, 8.0.305 or 8.0.402 (or later).
Or add a temporary Microsoft.Windows.SDK.NET.Ref reference which can be added with:

10.0.19041.38

It's really a known issue of unsynchronized release. WASDK 1.6 introduces breaking change in dependency, but released before it gets synchronized into .NET SDK. It's already checked into 8.0.402 but not reaching the release date.

@huoyaoyuan, do you have any idea, how to hotfix this? I'd like to create a WinUI new project, but right now, I am quite stack because of this.

The workaround is shown the error message that add a temporary <WindowsSdkPackageVersion>. Then everything should build.
