    text
    copied!<p>I'm giving a MVVMCross a spin, to see if it will be of use in some bigger projects coming up, and it's great. I like the navigation, viewModel location and general cross-platform approach, which is just what I need. However, I'm a bit stuck on splitting out some of the dependency injection depending on the platform.</p> <p>So, we have the basic application, with a shared portable library, that initialises the service references when starting up:</p> <pre class="lang-java prettyprint-override"><code> public TwitterSearchApp() { InitaliseServices(); } private void InitaliseServices() { this.RegisterServiceInstance&lt;ITwitterSearchProvider&gt;(new TwitterSearchProvider()); } </code></pre> <p>Fine. That defines the service implementations that will be used across all the platforms. But what about the situation where I will need different implementations on different platforms - for instance perhaps storage/caching, where the core requirement is the same, but needs to be handled differently on a phone than on a tablet.</p> <p>I thought it might go in Setup somewhere:</p> <pre class="lang-java prettyprint-override"><code>public class Setup : MvxBaseWinRTSetup { public Setup(Frame rootFrame): base(rootFrame) { } protected override MvxApplication CreateApp() { var app = new TwitterSearchApp();//set platorm specific IoC here maybe? return app; } protected override void AddPluginsLoaders(Cirrious.MvvmCross.Platform.MvxLoaderPluginRegistry loaders) { // or perhaps here? loaders.AddConventionalPlugin&lt;Cirrious.MvvmCross.Plugins.Visibility.WinRT.Plugin&gt;(); base.AddPluginsLoaders(loaders); } } </code></pre> <p>but I'm not sure. I've seen the references to replacing the ViewModel locator, but is there are similar way of replacing the other IoC services?</p> <p>thanks, great job on the framework in general, I really like how it works (apart from this bit, which I don't understand properly yet)</p> <p>Toby</p>
