When our application is poor in performance can cause slow interactions with the users, our app can be freeze sometimes, our app can reduce battery life or the device can get hot just because of an operation in a loop that’s never ended.Visual Studio 2022 has a refreshed look with new icons and theme that’s improves clarity and consistency, while keeping familiarity. Integrate the App Center SDK for automatic crash reporting.When we talk about code quality and performance we talk about the user’s experience. Collect real-time diagnostics, prioritize and fix critical issue. App Center tracks your builds through every release. Once you’ve beta tested a release candidate, promote the same build directly to Intune, Google Play, or App Store Connect. Promote validated builds to app stores.
Visual Studio Can'T Load Prism For Ios Mac Extension ToWe can improve our application performance in many ways. However, when we talk about quality and performance there is more than just implementing efficient code. If you are looking for the Prism CI Feed to take advantage of the latest Prism build you need to add. That feed provides the Visual Studio Mac Extension to provide the Prism Project & Item Templates as well as several code snippets.What is Xamarin?If your new in this world, just let’s start talking about what is XAMARIN. I’m telling you, this article is going to blow your mind if you work with Xamarin. Some of the downloads may only support certain Visual Studio versions.NET/.NET Core.NET is a free, cross-platform, open-source developer platform for building many different types of applications.What I have here is a recompilation of all of them with some best practices, tools, techniques, and so on. NET Framework on your machine.One of them is Xamarin Traditional (Or Xamarin Classic as some people call it). Xamarain TraditionalWhen we talk about Xamarin we have two approaches that we can follow. Xamarin is an abstraction layer that manages the communication of shared code with underlying platform code.So don’t go too dependency-heavy. If there are going to be databases involved, make sure you’re picking a good repository pattern.If you’re new in the Xamarin Forms world or you have a small project Xamarin.Forms Shell can be a good option because you will have probably all the tools you need to work with.Pick your dependencies wisely. So pick a good MVVM framework like Prism, ReactiveUI, MvvmLight, or just what you like. Performance Brand new app?The first thing is making good architecture choices. Xamarin.FormsOn the other hand Xamarin.Forms is a UI framework that allows developers to build Xamarin.iOS, Xamarin.Android, and Windows applications from a single shared codebase. Publisher for free on mac(For example the name of the page) Reduce unnecessary bindings: Don’t use bindings for content that can easily be set statically. These options are enabled by default but for older solutions, you need to enable them manually. Enable the XAML compiler*, Use compiled bindings*, Use fast renderers*. Already have an app?The architecture that you have is the best choice? If it’s not I wrote an ebook with 7 Tactics to structure your Projects with Xamarin.Forms that you can use today for both new projects and projects already created.In the official Microsoft Xamarin Documentation, there is a section focus on improving Xamarin.Forms app performance. So pick those wisely, and of course test often. Reduce the visual tree size: Reducing the number of elements on a page will make the page render faster. If you are using ListView be sure to Optimize performance with Initialization, Scrolling, and Interaction. Use CollectionView instead of ListView: CollectionView is more flexible, and performant than ListView. Optimize layout performance, Use asynchronous programming and Choose a dependency injection container carefully are specific tips that I recommend you to follow in the guide. Lazy Load Anything You Don’t Need Immediately. Don’t download all your data on startup. Don’t start/register all services right in the beginning, lazyload where possible. Startup PerformanceI know this is list is small but if you think about it I promise you, you will see the results immediately. In the performance section, I gave you some resources you can check.Try to avoid RelativeLayout and AbsoluteLayout as much as you can.Also in the same article, I gave some tips for Visual Studio and some tips to help you choose the best MVVM framework.In the same way, you have their tips for your XAML and C# projects and much more.You can read the complete article here. Creating apps with Xamarin.FormsI wrote an article talking about Examples, and tips for creating applications in Xamarin FormsIn this article, I talk about The three pillars to develop better applications that are:Also, I gave you some general tips and tips for increasing your application’s performance. ![]() Faster Application Startup using Custom Profiles with Startup Tracing. Faster Startup Times with Startup Tracing on Android. Using Custom AOT Profiles with Xamarin.Android. The best android emulator for pc i macA reference to the anonymous method can be stored in a field and used to unsubscribe from the eventJust remember to unsubscribe from events and remember to unsubscribe them before the subscriber object is disposed of. Unsubscribe from events and avoid anonymous delegates to prevent memory leaks Always detach Event Handlers and Dispose Observers LinkI know these things are something you’d hear again and again but trust me, it’s very important to remember these rules. Xamarin.Android Linker Tricks Part 1. Optimizing Xamarin Apps & Libraries with the Linker. So object A maintains a strong reference to object B, but object B maintains a weak reference to Object A.When your loading a page you need to think about user experience. On Xamarin.Android the GC handles that but in Xamarin.iOS we need to be careful.But hey we can Use a weak references to prevent immortal objects.A weak reference is created using the instance of the object being trapped. That is, when you declare a variable of a type that’s not a primitive/value type, you are declaring a strong reference.For example, here object A and object B have strong references to each other, and because of this, this creates what we call an immortal object.Immortal objects are circular strong references. NET, any normal reference to another object is a strong reference. LinkQuality Async/Await and Task best practicesI also wrote a post talking about this topic here.Async/ Await is one of those topics that you feel like you know a lot about but then you don’t. Stop Weak reference: Xamarin Community Toolkit: WeakEventManager. Alexyey Strakh’s Xamarin Show Episodes: Memory Management. Xamarin.Forms Memory Performance Best Practices. Something that I like is defining states like (busy, complete, canceled, etc.) and you can use that with some extra animations.Don’t bind things that can be set statically: if you have two labels, for example, one does describe something and the other one is what actually gets updated with some sort of data, don’t bind the descriptive label to the ViewModel, things like these will improve your app performance. Error handlers and Task wrappersI wrote an article about Global errors handling in Xamarin FormsMany times we may encounter unhandled exceptions that are very difficult to detect and log, and you must do so in order to handle errors in your application.
