Issue with upgrade Xamarin to .Net 6
I decided to try to upgrade the old Xamarin Forms app to .Net 6 and found an issue. Error: error XFVM001: Target Framework Version is currently v6.0 and must be greater than or equal to v9.0 in order to use Material on Android. Also, the output contains next line: warning XA4211: AndroidManifest.xml //uses-sdk/@android:targetSdkVersion '30' is less than $(TargetFrameworkVersion) ''. Using API-31 for ACW compilation. The new project file looks like that: <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <OutputType>exe</OutputType> <TargetFramework>net6.0-android</TargetFramework> <TargetFrameworkVersion>v30.0</TargetFrameworkVersion> </PropertyGroup> </Project> I suppose it is somehow related to Xamarin.Forms.Visual.Material. Any ideas what is wrong? Update: I tried to use the upgrade tool, but it failed too. It was not able to find the nugets for some reason. Update 2: https://github.com/byme8/expXamarin6Can we use Maui.Essentials without Maui UI framework?
Previously Xamarin.Essencials was an independed library that could be used with non-XamarinForms applications. Currently this library was rebranded into Maui.Essentials. Which raises a question, if this library become a part of Maui framework with hard dependency on it, or if it still can be used without this GUI framework. I don't see any references to the Maui framework at the moment except Microsoft.Maui.Graphics. Still, I want to see official confirmation stated somewhere. Use cases: 1. We want to be able to build Avalonia applications and use helpers from Maui.Essentials without referencing whole Maui framework. 2. Same about Uno Platform. It should be possible to use it with Maui.Essentials without Maui framework. 3. I also can imagine applications that are built with "net6-ios/android" targets with native UIs without "Forms" from MAUI. These applications will benefit from Maui.Essentials without unnecessary dependency from Maui framework. Thanks, Max Katsydan.Building OSS projects with C# and .NET

Migrate UWP App to MAUI Windows: Error after update with MSIX
I currently have a Xamarin Forms UWP App in the Microsoft Store. In the next months I want to update it to MAUI. For testing purposes and ensuring that all stored data are still available within the app, I want to simulate the Update of the Xamarin Forms app to MAUI with side loading for Windows. After installing the MAUI-msix-Update, an error appears: Is this a general problem or do I have a specific issue in my manifest? Sample app: https://github.com/reinhardlackner/SampleUpdateMauiApp Debugging is working correctly (I can start the UWP-App "SampleUpdateApp.UWP" in Debug mode... and after closing it I can start the MAUI-App "SampleNewUpdatedApp") - and the saved click-data from the UWP app are shown in the MAUI app: Sideloading-Update does not work: a) SampleUpdateApp.UWP - Right click => Publish... Sideloading Use test certificate Install UWP app appxbundle-file App opens => OK b) Install MAUI App as Update SampleNewUpdatedApp - Right click => Publish... Sideloading Use same certificate Create MSIX x86 publishing profile and version is 1.0.1 (update of Xamarin 1.0.0) Start created msix-Package and click on Update: Error message is shown: App installation failed with error message: Deployment Add operation with target volume C: on Package E965F79B-76C7-47E0-8308-4A503105EDE0_1.0.1.0_x86__ab06nvn9z6x6m from: (SampleNewUpdatedApp_1.0.1.0_x86.msix) failed with error 0x80073CF3. See http://go.microsoft.com/fwlink/?LinkId=235160 for help diagnosing app deployment issues. (0x80073cf3) If the Xamarin app was not installed before, the MAUI App can be installed correctly: Does anybody have an idea why the update installation is not possible? I assume it could be related with the Manifest-File... Manifest UWP: https://github.com/reinhardlackner/SampleUpdateMauiApp/blob/master/SampleUpdateApp.UWP/Package.appxmanifest Manifest MAUI: https://github.com/reinhardlackner/SampleUpdateMauiApp/blob/master/SampleNewUpdatedApp/Platforms/Windows/Package.appxmanifesthow does MAUI handle cross-platform gesture recognition
specifically how is it implemented for each platform and where can i find the code for each platform in regards to this gesture recognition for example, for MacOS i assume there would be some custom NSView implementation with overrides for the following TouchesBeganWithEvent TouchesMovedWithEvent TouchesEndedWithEvent TouchesCancelledWithEvent and for android i assume there would be similar with custom View implementation and OnTouchEvent method override i do not know for windows nor linux as i have not experimented with those platforms yet specifically i assume the gesture API MAUI provides is truely cross-platform and has no platform-dependant behavioural differences (with some exceptions for certain gestures for example a mouse or stylus CANNOT perform a two-finger scroll gesture however would be implemented via the scroll-wheel if present on the mouse on a mobile-device a two-finger scroll gesture does not make sense since it is usually just one finger for scrolling on a trackpad two-finger scrolling makes sense however regardless of HOW it is implemented, the api would provide a platform-independant way of tracking how much the user has scrolled, possibly accounting for some sensitivity setting the user can modify at will similar to pointer-acceleration settings for large and small monitors and high dpi and low dpi monitors
New Product Development : Xamarin forms Vs MAUI
Hi Team, Good Morning! We are working on revamping the UI of our Core Product App, which was built using Xamarin forms, and is now in 5.0.X, and since MAUI is evolving and is not available as a GA, kindly advise on following questions.. 1. Are there any other release for Xamarin planned 2. Until when do we have the support for Xamarin.Forms (Date would be critical) 2. For a enterprise like us, who are looking at investing on revamping the UI of the app, which path would be better to be taken up, if we go ahead with Xamarin way, how good is the support for migrating the app from Xamarin to MAUI planned from Microsoft... If the migration tool is available, approximately, how much manual effort may be needed to convert it 100% to MAUI.. Thanks in advance, the response from your end is going to be very critical in the decision making on the way we are going to forward further.. Thanks, Shri Guru Baskar
