installing WindowsAppSDK can lead to project errors

[vsfeedback]

This issue has been moved from a ticket on Developer Community.

[severity:It’s more difficult to complete my work]
Create a console app
Install nuget package WindowsAppSDK

You will get a brown error:

The project ‘myproject’ ran into a problem during the last operation: A numeric comparison was attempted on “$(TargetPlatformVersion)” that evaluates to “” instead of a number, in condition “‘$(TargetPlatformVersion)’ < ‘10.0.18362.0’”. C:\Users\username.nuget\packages\microsoft.windowsappsdk\1.3.230724000\buildTransitive\Microsoft.InteractiveExperiences.Common.targets You may need to reload the solution after fixing the problem.

And also an error while loading the project properties editor

Setting the following does not help…

net7.0-windows

That just generates a new error…

The project ‘myproject’ ran into a problem during the last operation: A numeric comparison was attempted on “$(TargetPlatformVersion)” that evaluates to “” instead of a number, in condition “‘$(TargetPlatformIdentifier)’ == ‘Windows’ and
‘$(TargetPlatformVersion)’ >= ‘8.0’”. C:\Users\usernam.nuget\packages\microsoft.windowsappsdk\1.3.230724000\buildTransitive\Microsoft.UI.Xaml.Markup.Compiler.interop.targets You may need to reload the solution after fixing the problem.

This is all a bad experience. And it’s not clear what I need to do when this happens other than search online for xaml code (or look in another project I have going) that might help the situation and manually insert it. I think this is configuration that could be automated generally.

I don’t see the solution on any of these pages…

[MSLukeWest]

Can the targets be updated to avoid this comparison when TargetPlatformVersion isn't set?

[kmgallahan]

Create a console app
Install nuget package WindowsAppSDK

@duncanmacmichael Wrong repo:

[MSLukeWest]

Looks like this has been known for a while, see #2338

Closing as Duplicate given Luke's comments.

[ramiz272]

replace this line in file : C:\Users\username.nuget\packages\microsoft.windowsappsdk\1.3.230724000\buildTransitive\Microsoft.InteractiveExperiences.Common.target

Line to replace:
<Ixp-UAPTargetVersion Condition="'$(TargetPlatformVersion)' &lt; '10.0.18362.0'">uap10.0.17763</Ixp-UAPTargetVersion>
TO:
<Ixp-UAPTargetVersion Condition=" '$(TargetPlatformVersion)' != '' And '$(TargetPlatformVersion)' &lt; '10.0.18362.0'">uap10.0.17763</Ixp-UAPTargetVersion>

WILL RESOLVE THIS ISSUE :)
