SkiaSharp.Views.Mac namespace does not exist

[Andrejf]

Description

If I create a fresh Cocoa project in Visual studio Mac and add SkiaSharp and SkiaSharp.View, everything works ok. By default mac apps are set to "Xamarin.Mac Modern" framework.

But when I edit the project, General, and change "target framework" to "Xamarin.Mac Full", then it can't find namespace.
SkiaSharp.Views.Mac

Is there something I can do to get this working?

Code

// can't find namespace SkiaSharp.Views.Mac;
using SkiaSharp.Views.Mac;

Expected Behavior

It should find the namespace SkiaSharp.Views.Mac

The issue still happens even if I re-add the nuget package.

Actual Behavior

It doesn't find SkiaSharp.Views.Mac.

Basic Information

• Version with issue: v1.68
• Last known good version:
• IDE: Visual Studio for Mac
• Platform Target Frameworks: Xamarin.Mac Full

• macOS: 10.14

The reason this bug shows is that when you select the full framework option, the app actually "transitions" from a "mac app" to a ".net framework app" and NuGet does not know that this particular app is actually both a "mac app" AND a "framework app".

A workaround would be to do one of two things:

• use packages.config and then change the HintPath to the Xamarin.Mac version
• don't reference the SkiaSharp.Views package, and manually add a reference to SkiaSharp.Views.Mac.dll

There has been an issue that has been opened, closed, reopened and eventually locked with a few PRs. But, not to be outdone, I have created a new PR that hopefully gets this in: NuGet/NuGet.Client#2572

This is not the greatest situation right now, but hopefully after this is merged, we can all be happy coders!

I have not had the opportunity to test this, but it seems we have a new option to turn macOS apps into real macOS apps: NuGet/NuGet.Client#2572 (comment)

Basically, you can add <MigrateToNewXMIdentifier>true</MigrateToNewXMIdentifier> in your project.
