Building Your First Mobile App With C# Net And Xamarin

So for cross platform we have React Native , Flutter , Xamarin (using C#). Xamarin.Essentials provides developers with cross-platform APIs for their mobile applications. Android, iOS, and UWP offer unique operating system and platform APIs that developers have access to all in C# leveraging Xamarin. Xamarin.Essentials provides a single cross-platform API that works with any Xamarin.Forms, Android, iOS, or UWP application that can be accessed from shared code no matter how the user interface is created. Xamarin.Forms also provide different functionalities and fast developments of mobile applications.

The library was born from a desire to share build processes from one app to the next without having to copy and paste a bunch of build scripts each of which could easily end up out of date. It is undoubtful that the Xamarin community is much smaller than those of iOS and Android. So, it would be really hard to find an experienced Xamarin developer. Although, this is growing every day with the support of Microsoft. Considering the stats from various sources, Xamarin community accounts for only 10 percent of the global mobile development society.Even with this number of Engineers, Xamarin provides extensive support to them.

You are really integrating the build systems across Visual Studio, Android, Xamarin, and XCode. We’ve already seen the Title property – this is a text field that specifies the title of the page. When the button is tapped, the login command will be run.

The developers do that by executing different code strategies such as portable class libraries and shared projects of the Xamarin app development services. Over the years this grew from the scripts I kept re-writing to scripts that I included out of the box with the Prism Quickstart templates. These features had nothing to do with Prism however, and I started looking at how these could be re-used for any Xamarin application. Over the years it has grown and had so many features added that I ultimately realized I better start writing a docs site as it has a solution for pretty much every problem I encounter when developing mobile apps. Xamarin is one of the solutions to it which actually is meant for cross-platform mobile app development where you can build Android, iOS, and Windows native application using a single codebase. The apps developed using Xamarin performs almost similar to the native Platform applications.

Creating A Simple Azure Mobile Apps Backend¶

The ListView has two built in DataTemplates for you to use, TextCell and ImageCell. Though the tutorial screen might not seem like much it has a pretty important job to do. You might be the kind of guy that instantly skips it and doesn’t pay any attention to it, but not all of your users are created equal. Creating a good tutorial screen is definitely worth your time and effort to get as much users as possible on board. Because the tutorial screen tells the user how to use your app it is also the place where you can highlight the features that separate this app from the rest of the pack.

  • For example, Xamarin.iOS not only includes support for mobile iOS, tvOS, watchOS, and macOS but also allowed developing for Beta iOS 13 months before the official stable release.
  • Right-click the TaskList.iOS project and select Build.
  • It also identifies the performance issues with your app before its release.
  • Below is an example of a simple UI created using XAML.
  • When not writing apps for fun she can be found speaking around the UK or Europe on her two favourite Microsoft technologies, Xamarin and Cognitive Services.

First, wouldn’t it be nice to write some code and get something working? Microsoft Azure has a great first-steps tutorial that takes you via the quickest possible route from creating a mobile backend to having a functional backend. I would like to take things a little slower so that we can understand what is going on while we are doing the process. We will have practically the same application at the end. The primary reason for going through this slowly is to ensure that all our build and run processes are set up properly.

Is Mobile App Mandatory For Your Business In 2022?

Xamarin makes use of both .NET and C# to give you a familiar and common platform for the creation of mobile apps which can run on different platforms. It does not mean that the write once and run anywhere formula is applicable. The code is in C# but the controls and properties are different. I tend to create a new App Service Plan for each mobile application. This is because the App Service Plan lives inside the Resource Group that you create. The process for creating an App Service Plan is straight forward.

We would be writing the logic of the app in the MainPage.xaml.cs file. The app is one wherein a user can click on any of the mood they are currently in and can get a quote that would address those feelings. So a user opens our app, sees a list of the moods, clicks on any of the mood and it displays an alert with the quote to address the mood — maybe elevate the feelings of someone that is sad. If you would rather develop code on your mac, the next sectiom is for you – it gets into the nitty gritty of developing the exact same app, but using Visual Studio for Mac instead. If you have got through the entire process outlined in this Chapter and built the application for each platform, then congratulations.

Enables quick building and managing of ‘good-enough’ internal apps to address specific business issues. Maintenance also means keeping up with each platform’s versions and updates, and here Xamarin has got you covered, too. For example, Xamarin.iOS not only includes support for mobile iOS, tvOS, watchOS, and macOS but also allowed developing for Beta iOS 13 months before the official stable release. Native UI. Xamarin.Forms takes advantage of standardized, guide-compliant controls and GUI elements, while dedicated iOS and Android options can be employed for unique visualizations or anything platform-specific.

Tutorial: Get Started With Xamarin In Visual Studio

In Visual Studio, UnderMyAwesomeXamarinApp.iOSopen the Info.plist file and select the Application tab. Here adjust the “Signing & Capabilities” settings of iOS by selecting your Apple developer account. Then select your target device and hit the “Run” button. If you have https://wizardsdev.com/ the Visual Studio Android Emulator installed, testing the Android version of your Xamarin app is simple. In the Visual Studio toolbar, pick the HelloWorldApp.Droid project and choose an Android device to emulate. Then, click the green Play button to start the emulator.

If Visual Studio hasn’t done so already, the missing NuGet packages for Azure Mobile Apps will be downloaded. If there are, check the typing for any changes you made. At this point, Visual Studio will create your backend project. If you open it up, you will see that it is very simple as for this view there isn’t any special events that are needed right now. Future posts in this series will cover data binding and the Model-View-ViewModel design pattern.

These layouts are StackLayout, AbsoluteLayout, RelativeLayout, GridLayout, ContentView, ScrollView and finally Frame. In this article I am going to highlight the main three that you will be more likely use whilst getting started creating mobile apps with Xamarin Forms. Do your apps require an appealing yet fairly standard GUI? A cross-platform GUI library for Android and iOS , Xamarin.Forms is currently one of the simplest ways to build cross-platform user interfaces that are compliant with the guidelines.

With all its flaws and limitations, Xamarin remains one of the most robust, extensive, and productive cross-platform app development platforms. With Microsoft’s strong backing and regular powerful updates, as well as a growing community of developers, the flaws are being taken care of, and the future is bright for this multifaceted ambitious project. Still, despite all that, Xamarin is rarely a mobile game developer’s first choice. Games, with all their interactive UI elements, simply don’t make room for meaningful code sharing and productivity gains. For the time being, ‘write once, play everywhere’ still remains Xamarin developers’ dream. Probably the biggest disadvantage of all hybrid app development products is the community, or rather its absence.

These services can help you throughout the development but it comes at an additional fee. XAML is another “language” that will be used to build user interface with Xamarin. With the Xamarin Native approach, each platform’s UI is written separately. So iOS still uses Storyboards, Android uses AXML, and UWP uses XAML.

Testing Your Xamarin App On Android

It is now an open source technology that has Xamarin SDK along with the libraries, runtime, and command line tools. Xamarin being an open source ensures that all tools are available with the MIT license . I’ve written a ton of XAML and it’s still confusing at times. Some things that should be simple are way more complicated than you’d expect.

Xamarin

Click the Local Machine button in your command bar to run the application. Right-Click the TaskList.UWP project again, then select Build. We are using the ReadAllItemsAsync() method to get a list of items, then we copy the items we received into the ObservableCollection`. This means that the value in the view-model drives the value in the UI. There is nothing within the UI that you can do to alter the state of the underlying property.

Its primary function is to display lists of data that normally require scrolling. Examples of a ListView in mobile apps would be your contacts list in your phone, text messages list, Twitter or Facebook feeds, maybe even a products page. For designers not used to programming markup, the syntax may seem rather strange, but the takeaway here is BOTH the XAML markup above and the C# code below produce the exact same UI. Xamarin Forms works by mapping the UI elements you create from your shared PCL UI code to their corresponding native equivalent on Windows, Android and iOS. So this means that your applications are completely native!

Click the Target server box and select the logical server you created earlier. Once the deployment has completed, you can move on to creating and linking a database. You can check the status of the deployment by clicking on the icon that looks like a bell in the top banner. Creating a Test Database through the App Service Data Connections allows you to create a free database. This option is not normally available through other SQL database creation flows.

This technique allows us to mock the backend service, as we shall see later on. Mocking the backend service is a great technique to rapidly iterate on the front end mobile client without getting tied into what the backend is doing. Xamarin allows us to build iOS applications directly from Visual Studio. This could be anything mobile course from a MacBook Air/Pro, to a Mac Mini in a drawer or closet in the office, or maybe even a Mac in the cloud. The Xamarin tools use SSH to connect to the Mac, which must be configured to build iOS apps from Visual Studio. I like to start on Android because emulators are available locally on both Windows and macOS.
