I developed a cross-platform applications with Xamarin.iOS.framework and Xamarin.Mac.framework and Mono.framework. I found some anxious information in https://dotnet.microsoft.com/en-us/platform/support/policy/xamarin . I want to know what's the quickest and most effective way to migrate my project to the latest support architecture? and what's the latest support architecture? Can you give me some document description and sample code to speed up my development. It's an urgent issue for me, If there's no a good solution to resolve the issue, I think it will stop my subsequent work。 I look forward to hearing from you. Thanks!

Hello, I want to know what's the quickest and most effective way to migrate my project to the latest support architecture? Your projects are Xamarin native projects (iOS, MacOS), you can upgrade them manually. (.NET Upgrade Assistant is currently only available for Windows, and only works with Xamarin.Forms projects.) . To upgrade your Xamarin native projects to .NET, you'll first have to update the projects to be SDK-style projects and then update your dependencies to .NET 6+. and what's the latest support architecture? .NET MAUI apps can be written for iOS 11 or higher, using the latest release of Xcode, macOS 10.15 or higher, using Mac Catalyst. Developing MAUI apps requires Visual Studio 2022 17.3 or greater, or Visual Studio 2022 for Mac 17.4 or greater. In addition, the project can target for .NET 6 or .NET 7.

Hello,

I want to know what's the quickest and most effective way to migrate my project to the latest support architecture?

Your projects are Xamarin native projects (iOS, MacOS), you can upgrade them manually. (.NET Upgrade Assistant is currently only available for Windows, and only works with Xamarin.Forms projects.) .

To upgrade your Xamarin native projects to .NET, you'll first have to update the projects to be SDK-style projects and then update your dependencies to .NET 6+.

and what's the latest support architecture?

.NET MAUI apps can be written for iOS 11 or higher, using the latest release of Xcode, macOS 10.15 or higher, using Mac Catalyst. Developing MAUI apps requires Visual Studio 2022 17.3 or greater, or Visual Studio 2022 for Mac 17.4 or greater. In addition, the project can target for .NET 6 or .NET 7. (.NET8 support in progress)

Can you give me some document description and sample code to speed up my development.

You can refer to the following docs:
Upgrade Xamarin.Android, Xamarin.iOS, and Xamarin.Mac projects to .NET - .NET MAUI | Microsoft Learn( When you create a new project for .NET MAC, you can select MacCatalyst or MacOS Application template. It's recommended that you choose MacOS Application template because your Xamarin.Mac application is a Cocoa App, and some features in AppKit are not supported in Maccatalyst )

Q&A is for English users, you can try to edit your extra questions in English. Your .NET App can be published to Appstore. Please see Publish a .NET MAUI Mac Catalyst app for Mac App Store distribution - .NET MAUI | Microsoft Learn

I'm not sure how you run the empty template macOS project, it should run under debug mode. You could share the detailed error message with me or create a new thread for further help.

The compiled file is not an archive package, you can check the final installer package size.

Xamarin native NuGet packages are not compatible with .NET 6+ unless they have been recompiled using .NET TFMs. It's not clear which third-party package you are using, you can look at the Frameworks tab on NuGetfor the package you're using, and check if the compatible frameworks contain net6.0-ios, net7.0-ios/net6.0-macos, net6.0-macos.

Code signing is available in VS for Mac, you can go to Project Properties window then go to Build-> Mac->Bundle Signing to select Signing identity and Provisioning profile. You can also add these settings in csproj file manually.

You can read the MAUI Roadmap- Roadmap · dotnet/maui Wiki · GitHub to see the schedule you want to know.

If you have any other issues, please feel free to post here.

Thanks Wenyan,

Maybe We have some Inconsistencies in understanding about Mac .NET project.

I find out 3 template in VS2022 for Mac, The first one is Mac .NET macOS Application, the second one is Mac .Net Mac Catalyst Application and the third one is Multiplatform .NET MAUI project.

In order to upgrade and migrate my Mac Xamarin native project to Microsoft new .NET architecture.

I have created a new project with .NET macOS Application, It's neither a .Net Mac Catalyst Application or a Multiplatform .NET MAUI Application.

I wonder if it's right to choose Mac .NET macOS Application project to upgrade my Xamarin Mac native application? And How to upgrade to Mac .NET macOS Application project. I think there are minimal changes than other two projects.

Do you give me some more supports or solution in migrating to Mac .NET macOS Application?

I don't have a stable experience in .NET macOS Application project with VS2022 for Mac and ask some questions on Friday.

In your previous reply, some is .NET MAUI project, some is .Net Mac Catalyst Application,

exactly I wonder the reply about .NET macOS Application.

In .NET macOS Application project, I can't find Build-> Mac->Bundle Signing in Project Properties window.

If you can give me other ways to communicate this problem. I want to get a feasible solution as soon as possible.

Thanks a lot!

I noticed that you create a new thread -How to upgrade Xamarin native Mac application project to Mac .NET macOS application project - Microsoft Q&A, let's focus on that.
