Even though I have an error, the message in the status bar in the bottom left reports “Rebuild All succeeded” – both can’t be right surely?.

I eventually noticed a couple of things that seemed a bit bizarre: The error reports “ The name ‘InitializeComponent’ does not exist in the current context.” Getting rid of the error CS0103 – ‘InitializeComponent’ does not exist in the current context Unfortunately my attempt to compile the project out of the box showed an error in the UWP project and a bunch of warning messages for the Android project.

Tip: Prepare to wait a while when building the solution for the first time – it needs to download a lot of NuGet packages. Compiling the solution led to multiple warnings and errors I’ll run through some of the symptoms of problems I encountered trying the things above, and how I fixed them.

Run the application in an Android Emulator.

Run the application in a Windows Phone Emulator.

Compile the application without error or warnings.

Things I wanted to do that didn’t work out of the box for me were: And now for the gremlins ex machinaĪfter this point, I hit a few snags. I normally just click OK here.Īt this point, you’ll have a simple Xamarin solution in Visual Studio 2017, which contains 4 projects – one for iOS, one for Android, one for UWP, and one shared project.Īlso notice that there is one file open in VS2017 after you create the solution – in the shared project. (I don’t have a Mac and I’d need Visual Studio Enterprise to use this anyway, so I normally click on the “Don’t show this again” box in the bottom left corner).įinally you’ll be prompted for the versions of Windows that you want the UWP flavour of your project to target. When you click OK, the project and files will be created, and a window like the one below will appear with instructions for setting up the Mac Agent.

I also chose to create a Shared Project because I only expect my code to be used in my application, rather than shared with other developers as a Portable Class Library (you can read more about the differences between Shared Projects and Portable Class Libraries here). I chose to use Xamarin.Forms (which allows developers to create cross platform user interfaces). Select File -> New Project to open the dialog below, and choose a name for the project:Īfter clicking OK on the dialog above (which chooses a Cross Platform App project type), the dialog will close and open a new project.

With Visual Studio 2017, it’s very easy just open up the setup wizard, select the Xamarin tools (as shown below) and just wait for it to install. Installing Xamarin tools for Visual Studio 2017 So instead of writing and managing three different codebases for three different platforms, developers can just write their code once and deploy it to different app-stores. With Xamarin tools built into Visual Studio, developers can create native applications in C# for Windows, Mac and Linux devices. Before we begin – what’s Xamarin and why should I use it?

If you’re on a different version of Windows, you might have different experiences to me (you can check your version by going to Windows Settings -> System -> About).

I use Windows 10 (and have installed the Creator’s Update) – this allows me to use Xamarin.Forms. Since I’ve recently started using Xamarin for cross platform development, I thought it would be nice to share with the community how I’ve got past some of the issues which tripped me up for a while when I was becoming familiar with it. This isn’t really a normal “getting started with Xamarin” tutorial – there’s lots of them already out there already, like this one – but hopefully anyone starting off with Xamarin will find it useful.
