Let's give it a try! Open Visual Studio and create a new Blank Xamarin.Forms project. If you've updated to the latest versions of Visual Studio and are working on new projects, Hot Reload is mostly 'there'. Hot Reload allows us to avoid the expensive roundtrip of building and deploying the app to test UI tweaks, lettings us preview it directly on a device (which is the best method for testing our UI work).Īs changes made to XAML files are instantly updated in the running app, in practice Hot Reload makes the simulator a kind of real-time previewer. The XAML Hot Reload feature takes changes to a XAML file and instantly updates it in our running app. Let's take a look at them! XAML Hot Reload XAML Previewer: is a tool built to Visual Studio XAML editor, that allows us to have instant insight on the UI that you're working.XAML Hot Reload: allows us to make changes to change XAML code and have it updated on a running instance of your app, either on a simulator or a real device.Lucky as Xamarin.Forms developers, we have some great tools to facilitate this jobs: Commonly you do several roundtrips between edits to test every dynamic and interactive aspect of the interface. Writing a complex UI is for the most part a trial and error exercise. As developers we think of UI elements as dynamic components and interactive components. Drawing UI from an application framework is not like composing it on a tool like Photoshop by drawing and styling primitives (although its possible through shapes). Its hard to write UI code without seeing its actual output. This allows developers to have full control over the rendering of the interface and split it into reusable components, but comes with drawbacks. The most established front-end development workflows are based on transcribing designs based on static images to the components that actually render that screen at runtime.įor the Xamarin.Forms developers, UI's are written entirely in code, either through XAML or C#. Modern apps tends to use complex designs and need to adapt to the growing number of device sizes and form-factors. Building UI's has always been a hard job.
