Getting Started

Install Visual Studio 2015

VS 2015 is required for developing Xamarin.Forms. If you do not already have it installed, you can download it here. VS 2015 Community is completely free. If you are installing VS 2015 for the first time, select the "Custom" installation type and select the following from the features list to install:

  • C#/.NET (Xamarin v4.0.3)
  • Universal Windows App Development Tools
  • Windows 8.1 and Windows Phone 8.0/8.1 Tools

We also recommend installing Microsoft Visual Studio Emulator for Android as well as Emulators for Windows Phone 8.1. If you already have VS 2015 installed, you can verify that these features are installed by modifying the VS 2015 installation via the Control Panel.

Install Additional Features

After installing VS 2015, you will also need to install the following:

  • Bing Maps SDK for Windows 8.1 Store apps -- you can find this in Tools > Extensions and Updates and searching for "bing" in the Online pane.
  • Android SDKs -- you can install these via Tools > Android > Android SDK Manager.
Solution Configuration

Upon opening the Xamarin.Forms solution, you will find that there are a number of errors and warnings under the Error List pane; you can resolve this by changing the filter of Build + IntelliSense to Build Only. At this point, you should be able to successfully build the solution.

By default, the Xamarin.Forms.Controls project does not have a configuration for various API keys to access certain features on each platform (e.g. maps). When building the solution the first time, a controlgallery.config file will be generated inside that project, which looks like this:


You will have to obtain your own API keys for each of these services, inserted directly after the identifier (e.g. Win8MapsAuthKey:abcdefghijklmnopqrstuvwxyz). You can find out how to obtain each of these as follows:

Due to the way that Android works, the maps API key cannot be injected at runtime. As a result, you will have to add this key to the MapsKey.cs file under Xamarin.Forms.ControlGallery.Android/Properties:

[assembly: Android.App.MetaData("com.google.android.maps.v2.API_KEY", Value = "INSERT_KEY_HERE")]

You can find out how to obtain a Google Maps API key here.

Coding Style

We follow the style used by the .NET Foundation, with two primary exceptions:

  • We do not use the private keyword as it is the default accessibility level in C#.
  • We use hard tabs over spaces. You can change this setting in VS 2015 via Tools > Options and navigating to Text Editor > C# and selecting the "Keep tabs" radio option.
  • Lines should be limited to a max of 120 characters (or as close as possible within reason).
