Additional context

[jevansaks]

This is intentional behavior. We need to enforce that consuming apps are running in the right compatibility mode when running on the latest OS. Note that your TargetPlatformVersion can be 17763 but you can keep your Minimum version the same.

If retargeting is a problem for you, we'd like to understand why.

There is an escape hatch, you can set the following in your project:

<SkipMicrosoftUIXamlCheckTargetPlatformVersion>true</SkipMicrosoftUIXamlCheckTargetPlatformVersion>

But you may run in to bugs due to running in older compatibility modes in newer versions of Windows.

I'm not sure we're on the same page. Compatible OS'es:

Windows Insider Preview (17135+)
April 2018 Update (17134)
Fall Creators Update (16299)
Creators Update (15063)
Anniversary Update (14393)

My installed OS version is 17134 so I can't set the Target to 17763 unless there's a way to update the SDK some way?

[jevansaks]

You can install it via the Visual Studio Installer (it's in the Individual Components list) or you can use the standalone installer. https://developer.microsoft.com/en-US/windows/downloads/windows-10-sdk has more details.

So the "Supported OS versions" is somewhat outdated I guess. Thanks anyway.

You're saying that it should say 17763? Yes we should probably list the fall creator's update. I'll fix it, thanks!
