MvvmCross - v3 - Writing a First App

<h1>
    MvvmCross - A CrossPlatform Mvvm Sample</h1>
<h2>
    Introduction</h2>
<p>
    MvvmCross is a truely Cross-Platform Mvvm C# Framework.</p>
<p>
    This series&nbsp;of&nbsp;articles will&nbsp;walk you through the use of MvvmCross to produce&nbsp;a first simple app - a TipCalculator.</p>
<p>
    Beyond this first walkthrough, there are many other things that MvvmCross can do - but this article will just stick to the basics for now!</p>
<h2>
    Background</h2>
<p>
    MvvmCross is now 18 months old.</p>
<p>
    This article is about v3 - code-named Hot Tuna.</p>
<h2>
    Using the code</h2>
<p>
    The code for this article is in: <a href="https://github.com/slodge/MvvmCross-Tutorials/tree/master/TipCalc">https://github.com/slodge/MvvmCross-Tutorials/tree/master/TipCalc</a></p>
<p>
    Setting up MvvmCross v3 is quite awkward at the moment - you need to setup Microsoft SDKs, Xamarin 2.0 products and some strange Portable Class Library (PCL) hacks.</p>
<p>
    This setup is documented on <a href="http://slodge.blogspot.co.uk/2012/12/cross-platform-winrt-monodroid.html">http://slodge.blogspot.co.uk/2012/12/cross-platform-winrt-monodroid.html</a></p>
<p>
    This setup is changing in the next few weeks -&nbsp;official Xamarin PCL support is coming -&nbsp;I will update this article when the new simpler steps arrive</p>
<h2>
    The Target</h2>
<p>
    In this first Model-View-ViewModel project, we&rsquo;ll aim to create a simple single screen cross-platform application for calculating the tip at a restaurant.</p>
<p>
    Here&#39;s a sketch of where we hope to end up:</p>

<p>
    The goals of this first application are all about <strong>introducing</strong>:</p>
<ol>
    <li>
        the general structure of MvvmCross applications</li>
    <li>
        some of the code elements required in all MvvmCross applications</li>
    <li>
        how data-binding support on Xamarin.Android and Xamarin.iOS (the products formerly known as Mono for Android and MonoTouch)</li>
</ol>
<p>
    Within this guide, we won&#39;t attempt to provide any introduction to the Apple, Google, Microsoft, and Xamarin products and platforms - there are plenty of guides available already for all of those. Instead, we&#39;ll focus instead on pure, unadulterated MvvmCross Nirvana.</p>
