Weird Regression in .net 8 Maui Project: "Unable to find package Microsoft.AspNetCore.App.Runtime.win-arm"

[dgerding]

Hi All,
Using the hot of the presses preview. Can't get around a build error that cropped up in the last steps of migrating a .net 7 maui solution to .net preview latest.

NU1102 Unable to find package Microsoft.AspNetCore.App.Runtime.win-arm with version 8.0.0-preview.6.23329.11

I've manually uninstalled and reinstalled the Preview SDK and done same with Visual Studio. Currently only have 2023 17.7.6 installed and still no luck.

Any ideas or just work arounds appreciated.

Just a follow up that no matter what I try, I can't seem to get around the following build error on this machine. I've removed all VS and .net sdk instances, restarted a couple of times and then installed today's (preview 6).

---csproj : error NU1102: Unable to find package Microsoft.AspNetCore.App.Runtime.win-arm with version (= 8.0.0-preview.6.23329.11)

It might help to include sources from https://github.com/dotnet/maui/blob/main/NuGet.config. Just once to get the dependencies. It helped me once. Maybe it will help, maybe not.

Thanks, @MartyIX, that worked for one build and then failed again. Found a different solution, see below.

Hi All,
It turns out that the problem was an old explicit package include in the csproj file for

<PackageReference Include="Microsoft.WindowsAppSDK" Version="1.4.230628000-preview1" />

Removing the explicit package reference for Microsoft.WindowsAppSDK in csproj fixes the problem, presumably by permitting upstream dependencies to now "auto include" this reference as needed.

Hope this helps someone else.
