Building WinUIGallery.DesktopWap gives NETSDK1005 error

[rcohn]

Hello -

I downloaded the WinUIGallery sources and attempted to build WinUIGallery.DesktopWap. I'm getting this error:

1>------ Build started: Project: WinUIGallery.DesktopWap, Configuration: Debug x64 ------ Failed to restore C:\Users\rcohn\Downloads\WinUI-Gallery-main\WinUI-Gallery-main\WinUIGallery\WinUIGallery.DesktopWap.csproj (in 11 ms). Failed to restore C:\Users\rcohn\Downloads\WinUI-Gallery-main\WinUI-Gallery-main\WinUIGallery\WinUIGallery.DesktopWap.Package.wapproj (in 58 ms). NuGet package restore failed. Please see Error List window for detailed warnings and errors. 1>C:\Program Files\dotnet\sdk\6.0.307\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets(267,5): error NETSDK1005: Assets file 'C:\Users\rcohn\Downloads\WinUI-Gallery-main\WinUI-Gallery-main\WinUIGallery\obj\WinUIGallery.DesktopWap\project.assets.json' doesn't have a target for 'net6.0'. Ensure that restore has run and that you have included 'net6.0' in the TargetFrameworks for your project. 1>Done building project "WinUIGallery.DesktopWap.csproj" -- FAILED.

As near as I understand it, this is some kind of NuGet package error. I attempted to do a "Restore NuGet packages", but that failed.

I'm using Visual Studio 2022 17.2.5 on Windows 11. Could you please give some advice here?

Thanks very much.
Robert

Solution found by @rcohn:

However, since my last comment, it seems I have found a solution. There were some suggestions in: https://stackoverflow.com/questions/56558843/local-source-of-nuget-packages-doesnt-exist, one of which helped:
dotnet new nugetconfig
followed by:
dotnet restore WinUIGallery.DesktopWap.csproj

So now I am able to build WinUIGallery.DesktopWap and publish it. The dotnet restore, by itself, did not work until I did the dotnet new command. For some reason project.assets.json had an empty "targets" field before the nuget commands. Now, "targets" is filled in and targeted to net6.0-windows10.0.18362.

Did you install the Windows App SDK extension? I also ran into an issue restoring the packages and installing the extension fixed this issue for me.

Great to hear that you were able to get the project compiling! Would you like to post your comment as top level answer so it can be marked as solution?

[rcohn]

Yes, that would be fine. Is there a way I can do that, or do you do that as moderator?
Thanks.

Since you asked the question, you can also mark your answer as the solution. Otherwise, I would also be more than happy to do that for you if it doesn't work.

I'm not seeing a way to mark my reply as the answer. I see only the one "mark as answer" button in one of your previous comments. There doesn't seem to be a way to mark a comment within a thread as the answer. But anyway, I pressed the button and people can read further to get the actual answer.

Unfortunately, you cannot mark a comment to an answer as solution, that's why I suggested posting your comment as a top level answer. Anyways, I've updated my comment to show the solution you found.
