Creating Xamarin.Forms Solution

In this post, we will see how to create a simple Xamarin.Forms application. We will be using Xamarin Studio as our IDE of choice; the initial setup is almost identical using Visual Studio. There is one cavate when determining your developer environment, Mac OS X is required to compile iOS applications and Windows is required to compile Windows applications (thanks Google for playing nice). In a later blog post, I will cover how to add a Windows application to an existing project created on Mac OS X using a Windows virtual machine.

To get started, first open Xamarin Studio on a Mac. From the menu bar, select File > New > Solution. The following dialog will appear. This dialog will allow you to select which project template to use for your solution. Select Multiplatform > App > Forms App and then click Next.

You will then see another dialog to configure the main settings for your Forms App.

In the App Name textfield, put the name of your application. If the name of the application is more than one word,  Xamarin Studio will add dashes to the complete package name. This can have unintended consequences later on when using advanced features such as intent filtering. My recommendation is to not add any spaces using this dialog and we will fix the display name after the solution has been created (iOS: Open Info.plist > Update Application Name textfield to the desired display name | Android: Right Click on Android Project > Select Android Application > Update Application Name textfield to the desired display name).

In the next textfield, type your organization’s identifier such as a company name. It is customary to prefix the name of your organization with “com.”; the organization identifier and app name will be concatenated to make your applications’ package name (e.g. com.MyCompany.HelloForms).

Next, select which platforms you intend to target. Notice that only Android and iOS are available, this is due to the fact that we are using a Mac. We will add Windows to the solution in a later blog post.

Under the Shared Code section you have the option between using a Portable Class Library (PCL) or a Shared Library. There are pros and cons to using either option. For this example, we will use a PCL since it is the simplest of the two and is the preferred method.

Lastly, you will have the option to use XAML for building your User Interface (UI). This option does not prevent you from using C# to create some or even all your views, it simply indicates your preference. If you are not familiar with XAML, it stands for Extensible Application Markup Language and is an XML based language used to create UIs. XAML is not unique to Xamarin; Microsoft actually developed it and is used with a multitude of technologies such as SilverLight and WPF. For this demo, leave XAML left checked. Then click Next.

In the final dialog, you will configure your main project settings.

In the Project Name textfield, put the name of your application. This will be used as the name of your PCL project and the prefix to your Android and iOS projects (e.g. HelloForms.Droid and HelloForms.iOS).

In the Solution Name textfield, put the name of your solution. This does not have to match your project name.

Location indicates where on the file system your new solution will be located.

Version Control instantiates a local git repository inside the solution directory. We will not be using git for this demo.

Leave Xamarin Test Cloud unchecked for this demo. Click Next.

We now have a fully functioning application. In the next blog post, we will go over the structure of the solution in detail.
