Wpf Net5 and MSIX

[easly1989]

Hello, I'm trying to setup a Continuous Integration action, based on the ci.yaml provided in this repository. I'm using net5 for my Wpf application, and visual studio 2019 preview. Locally I'm able to build and deploy without problems, but on the github action I receive this error

D:\a\weekly_diet_organizer\weekly_diet_organizer\DietOrganizer.Wap\DietOrganizer.Wap.wapproj : error NU1201: Project DietOrganizer is not compatible with uap10.0.16299 (UAP,Version=v10.0.16299). Project DietOrganizer supports: net5.0-windows7.0 (.NETCoreApp,Version=v5.0) [D:\a\weekly_diet_organizer\weekly_diet_organizer\DietOrganizer.sln]

Can someone help me? Is there something I can do to make it work?

Thank you in advance

I see 2 issues:

VS 2019 Preview

1. GitHub Actions runners do not use VS 2019 Preview (v 16.9). the windows-latest runner uses VS 2019 16.8.

This is why it works locally for you, but not on GitHub Actions build

2. Target Framework I see that your WPF project's TFM is set to Windows 7

<TargetFramework>net5.0-windows7.0</TargetFramework>

As far as a solution goes, I'm not exactly sure how you can use a UWP packaging project for a Windows 7 TFM, I know MSIX works downlevel via a special package manager install. Try setting the WPF project's TFM to

<TargetFramework>net5.0-windows10.0.19041.0</TargetFramework>

Maybe try multiple TFMS

<TargetFrameworks>net5.0-windows10.0.19041.0;net5.0-windows7.0</TargetFrameworks>

In the project the targetframework it is set to

net5.0-windows

I'll try all your suggestions and let you know! Thank you

[LanceMcCarthy]

Oh! Maybe windows7.0 was defaulted by the SDK. Try setting it to just net5.0-windows10.0.19041.0
