We migrated our app from xamarin to MAUI on .NET 8 and are now on .NET 9. Initially everything was a big pain. Now things are kinda smooth, comparable to how they were on xamarin. We are not using Shell! But this is just for our project, I see some other people still struggle more. Generally you still need to work around a lot of smaller quirks, but that was already the case in xamarin. My biggest pain is that the performance on Android is terrible. Regarding rider it works quite fine now. There is some issues for me still where builds will randomly fail and debugging/hot reloading will not work and I need to clean the project and delete .idea files, this is a pain sometimes. MAUI is not great but it does its job for the most part. I would still be hesitant to recommend anyone using it because of all the quirks, performance issues and instabilities. |

As far as I know, Xamarin support will end in May 2024, right? For me there is no question about MAUI team regarding the MAUI issues, the guys give the best of themselves. But what I keep asking myself is if c-suite from Microsoft is still alive on this planet earth? Because how can you remove support from Xamarin when MAUI is not yet mature (even if it was released 2 years ago)? Maybe Microsoft also hopes that there will only be programmers in this year 2025 and after that no more because AI will take over everything (Mark Zuckerberg)? pc |

To be fair it seems we are going back rather than going forward. I hope things will get better but for now I'm not very confident about it. |

@phillippschmedt Could you try #27259 if it fixes your performance issue? Any feedback there is tracked by the MAUI team, so it's useful to present there any positive impact, if any. |

Well, my main issue nowadays is regarding tooling. Still an awful experience, either using Rider, or Visual Studio for Windows, (rider is better though). The classic clean, delete bin/objs, fonts not being rendered, etc, hot reload stopping to work. On the positive side, my experience so far has been good regarding the framework itself. Not that many issues regarding performance ( thgough previous knowledge from Xamarin helps a lot, Visual Tree, simplification of xaml, some controls in pure c#, MVVM, less packages). One thing people keep forgetting - debug is WAY slower in MAUI rather than xamarin. but like 4/5 times slower. If you go to a release version the app seems like another one. Still, there is a long road ahead, with many critical bugs, (or just simple ones) to be fixed, but things are going forward at least |

I'm aware about the debug and that's fine... it's the release that I'm complaining about. Everything is slow without reason. I used a syncfusion calendar component for one of my client's app but it was too slow and I had to rewrite it from scratch to make it decent so it's not how I write code. I loved Xamarin and love C# but this team need more resources to do something good |

#27042 seems to improve perf considerably for all platforms. See the perf impact section. There is much more that can be achieved with this approach. But even with this PR, a big group of apps might turn from slow to okay performance-wise. One can even somehow download nugets for that PR to check it out now, but I'm not sure how at the moment. |

With MAUI I only use Blazor and don't really experience these performance problems. I have the impression that the majority of MAUI problems are caused by XAML, but can @MartyIX please clarify this because you are dealing with it? Thanks. |

More in-depth reasons are mentioned in the PR. But in short: MAUI on Windows/Android/etc. requires interop calls to propagate virtual views changes to platform views. These are costly, #27042 reduces significantly the number of such calls. Personally, I don't think that XAML is the issue. |

the nugets are on Generally speaking, I have to say that the performance in release mode is now great if you have the resources and the will to optimize your code and xaml |

Does this already contain #27042?
Not sure about the comment about optimizing code and xaml..
Is this related to this build or a generic comment?

That is my own general opinion regarding performance at the moment, even without #27042 It helps a lot to create ViewModels in background threads and only set the ViewModel in the view as a BindingContext when all properties have their value. Especially IsVisible properties. And of course don't create unnecessary controls and then hide them with IsVisible="false". |

@marcojak I was talking about some general considerations ( most of them are pointed in the performance section of MAUI). Keep the Visual Tree as slim as possible. One of the advantages or disadvantages of XAML is that you can have the same layout constructed in different ways ( VerticalStacklayouts, grids, etc): I tend to use as many Grids as possible. Regarding the VMs, the same comment as @baaaaif , background whenever possible, async awaits, offload from MainThread whenever possible ( see ConfigureAwaits in your HTTP Requests and other possible tasks) |

OK, I overlooked one thing - for me this is only the case on iOS and Android if UseInterpreter=False(iOS) / RunAOTCompilation=True(Android) are set. |

These are all great suggestions but unfortunately, MAUI is for some reason slower than Xamarin Forms. This is true especially for iOS where X.F. was really smooth on iOS and really slow with MAUI. In addition to this, I see some strange behaviours in one of my sporting from XF to MAUI (but I still have to investigate them so I haven't opened any issues yet), where some controls just disappear from my CollectionView and others are not properly updated. I'm not saying it's all bad, but just that there is a lot of room for improvements |

I think in 2025 we should continue to accelerate the resolution of bugs and optimize the logic at the same time. By using AI analysis to improve the code, the problem of maui being slow may be improved. |

Just as an update. I've published my client latest app yesterday, both on Android and iOS. |

Personally, I had to create a customised Calendar with a custom cell for each day. Also getting rid of the CarouselView, replaced by another control made by other developers, solved almost all problems, we went from more than 400 crashes in 1 day to just 1 today. I really hope the team will get rid of the CarouselView and replace it with another component. Regarding Blazor, unfortunately, I have no real experience with it (I've done a few tests to see if it was mature enough) so I cannot say. My feeling anyway is that Blazor shouldn't have the same performance issues |

It's a pull request, so one can download nugets for the PR. It's not in the nightly feed because it was not merged. And it is a good question if it will be ever merged because @albyrock87 presented #27259 which seems to be an even better implementation of what I wanted to achieve. You can check out the perf improvements of his PR1. Footnotes

Many older discussions stem from the rocky transition period of the past few years. But what’s MAUI’s current state?
I work with MvvmCross but am considering making a relatively simple MAUI app, without much media or other UI-heavy tasks.
Side question: Is Rider’s support for MAUI any good?
