Just like our last projects, we are going to set up another IoC container using Autofac. Let's first add the Autofac nuget packages to all projects in the solution. We can then copy the IoC folder from the Stocklist.Portable project in Chapter 5, Building a Stocklist Application. Make sure you include both the IoC.cs and IModule.cs files.

Now let's hop over to the native projects, add the Modules folder in the iOS and Android projects, and implement IOSModule.cs and DroidModule.cs:

public class IOSModule : IModule 
    { 
        #region Public Methods
        public void Register(ContainerBuilder builder)
        {
           builder.RegisterType<SQLiteSetup>().As<ISQLiteSetup>().SingleInstance();
           builder.RegisterType<SQLitePlatformIOS>().As<ISQLitePlatform>().SingleInstance();
        }
        #endregion 
    }

and the DroidModule,

public class DroidModule : IModule
    {
        #region Public Methods
        public void Register(ContainerBuilder builder) 
        {
            builder.RegisterType<SQLiteSetup>().As<ISQLiteSetup>().SingleInstance();
            builder.RegisterType<SQLitePlatformAndroid>().As<ISQLitePlatform>().SingleInstance();
        }
    #endregion 
}

Inside both of the aforementioned modules we are registering the SQLiteSetup and SQLitePlatformIOS/Droid objects so the SQLiteStorage implementation can use these items inside the FileStorage.Portable project.

Before we get back to finishing off the SQLiteStorage implementation, we are going to set up a useful logging approach that can be used in all cross-platform applications.
