Build Xamarin apps with VS Code to M1 Macs, iPhones & Android by The First Prototype Dev Genius
So, first in this Xamarin Tutorial, I am going to assume that you are using Windows 10 and have a flavor of Visual Studio 2015 installed on your machine. Even under that assumption, we need to make sure that you have the Xamarin tools installed. Now that we have the basic definition and understanding of what Xamarin is, we can put that behind us and make sure that we have the tools necessary to start developing. For this, my plan is to stick with as many Microsoft technologies as possible.
With portable class libraries, the code is compiled separately and referenced in each project like any normal class library. The big difference here is that you have access to a subset of .NET that is compatible with all the target platforms. So, for example, you could use System.Net.Http, but trying to access hardware, such as, the camera API is not available. You could, however, use a generalized interface that uses dependency injection. Visual Studio will start creating your Xamarin solution. However, since we are targeting Universal Windows Platform applications in our project, you will be prompted for your Target and Minimum versions of Windows.
Build Your First for iOS & Android App with Xamarin and Visual Studio
The platform gets even better for faster app development and minimum maintenance because you can create a shared logic between different app versions for platforms like Android, iOS, and UWP. Start using Xamarin to code, test, and debug in one familiar IDE, Visual Studio.

We have hardcoded the values of the message for corresponding mood, but we could extend it to talk to maybe videos APIs or other external APIs. Also, instead of displaying just an alert we could send the user to a new page. Finally, check the https://wizardsdev.com/en/news/new-mobile-course/ properties of the json file and change the Build Action to Embedded Resource. We want that when a user clicks the button, we get the text of that button , then we load the json file where we have a list of the mood and corresponding quotes.
- Another dialog prompting for the type of cross-platform project will be displayed.
- However, there is a high demand for Xamarin developers because the supply is very low.
- The entire world is now surrounded by billions and trillions of mobile Tech which is inevitable.
- The Xamarin.Forms project template in Visual Studio for Windows will use a .NET Standard library instead of a Portable Class Library for its core library project.
- Select the Startup Project and Proceed to deploy the application on either your Emulator, iOS or Android Device.
- There are a few requirements that must be adhered to when developing for iOS in Visual Studio.
There is splash_screen.xml which is used for defining a style called “MyTheme.Splash” in values/styles.xml. 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. For us to build our iOS project, we will need to connect your Visual Studio iOS project to a Mac. To do this for the first time, all you do is attempt to build the project.
Check the Backend
For more information, seeDevelopment Mode and Update Your Data Model. A. The EditItemViewModel ViewModel is used to both create new items and to modify existing items. When creating or modifying an item, the user needs the UI to set the Priority of an item. The app uses a single model, Item, which implements IRealmObject. We have three views, one for logging in , another for viewing Items , and a third for editing and creating new items.
You should see the Visual Studio iOS Simulator with your application. Next, you will be prompted for your username and password. Select Projects, then Solution, then select your new PCL from the list. You will also probably see the following dialog while it is creating the solution.

It is always advisable to test on a minimum target platform, e.g., API 10 Android 2.3 so as to ensure your App works across all Android platforms. In our case, we name it “helloWorld” and save it in the default location provided. Next, click the OK button for the new “helloXamarin” project to load.
