nuget looking for (old, not mono) Microsoft.NETCore.App.Runtime.maccatalyst-arm64

[spouliot]

This is semi-related to https://github.com/dotnet/sdk/issues/21877 where a .csproj has several target frameworks.

<TargetFrameworks>net6.0-android;net6.0-ios;net6.0-maccatalyst;net6.0-macos</TargetFrameworks>

This leads to the known issues :( but this one seems different.

The main project imports another file that contains

<TargetFramework>net6.0-macos</TargetFramework>
<RuntimeIdentifier>osx-arm64</RuntimeIdentifier>

That's to avoid (some) of the issues with https://github.com/dotnet/sdk/issues/21877

That works well to do a dotnet restore for macOS. However switching to MacCatalyst leads to nuget errors to retrieve the runtime package.

<TargetFramework>net6.0-maccatalyst</TargetFramework>
<RuntimeIdentifier>maccatalyst-arm64</RuntimeIdentifier>

Steps to Reproduce

1. dotnet restore inside a project with multiple framework targets.

$ dotnet restore

  Failed to restore /Users/poupou/git/uno/uno-debug-test/DebugMyApp/DebugMyApp.Mobile/DebugMyApp.Mobile.csproj (in 609 ms).

• Microsoft.NETCore.App.Runtime.maccatalyst-arm64 does not exists (anymore)
• Microsoft.NETCore.App.Runtime.Mono.maccatalyst-arm64 was its replacement.
• Somehow, somewhere, something is still looking for the old/original name.
• The error comes from nuget but I don't think it has the knowledge of the runtime filenames.

Expected Behavior

Successful restore.

$ dotnet restore                                                                                                                         Determining projects to restore...
  Restored /Users/poupou/git/DebugMyApp/DebugMyApp.Mobile/DebugMyApp.Mobile.csproj (in 1.99 sec).

Actual Behavior

Nuget error NU1102.

Also, when switching to iOS dotnet restore works just fine

<TargetFramework>net6.0-ios</TargetFramework>
<RuntimeIdentifier>iossimulator-arm64</RuntimeIdentifier>

Thanks, we will have a look at it!

It does not seems possible to have a project with multiple platforms that target MacCatalyst with arm64 :(

[rolfbjarne]

This error:

error NETSDK1047: Assets file ...

occurs when a project hasn't been restored for the RID in question, and you're passing in --no-restore to dotnet build, so that makes sense.

[rolfbjarne]

This csproj restores just fine for me:

<?xml version="1.0" encoding="utf-8"?>
<Project Sdk="Microsoft.NET.Sdk">
	<PropertyGroup>
		<TargetFrameworks>net6.0-ios;net6.0-maccatalyst;net6.0-macos</TargetFrameworks>
		<RuntimeIdentifier>maccatalyst-arm64</RuntimeIdentifier>
	</PropertyGroup>
</Project>

$ dotnet restore

Can you provide a test project?

@rolfbjarne yes, restore works - but you can't build a maccatalyst-arm64 binary of a default maui template.

dotnet build -f:net6.0-maccatalyst -r:maccatalyst-arm64                                                                                                                                     MSBuild version 17.3.0+92e077650 for .NET

Since you're back to https://github.com/dotnet/sdk/issues/21877 which mix SDK, like Microsoft.iOS.Sdk, and identifiers, like maccatalyst-arm64). The workaround is where the --no-restore is being used.

When I restore independently and build with --no-restore then I hit the above error.

How would you build the maccatalyst-arm64 binary of a default maui template from the command-line ?

[rolfbjarne]

This seems to work for me:

$ dotnet restore /p:RuntimeIdentifier=maccatalyst-arm64
$ dotnet build -f net6.0-maccatalyst /p:RuntimeIdentifier=maccatalyst-arm64 --no-restore *.csproj

@rolfbjarne was your project based on the default MAUI template for all (at least multiple) platforms ?

$ dotnet restore /p:RuntimeIdentifier=maccatalyst-arm64                                                                                                                                                Determining projects to restore...

Try updating to 15.4.447: https://github.com/xamarin/xamarin-macios/releases/tag/dotnet-6.0.4xx-447, where we've done this: https://github.com/xamarin/xamarin-macios/pull/15491

[spouliot]

Thanks! Works for MAUI and likely on my original code (need to remove some workaround to try it). I thought I updated to 447 but I now remember the downloads were failing at the time and forgot to try updating again.
