title: How to load a module and navigate to the module? Prism
body: <p>I have two modules: <code>ModuleLogging</code> and <code>ModuleItems</code>.
  My <code>Shell</code> has declaration:</p>
  
  <pre><code>&lt;Grid&gt;
     &lt;DockPanel LastChildFill="True"&gt;
      &lt;ContentControl  DockPanel.Dock="Top" prism:RegionManager.RegionName="{x:Static inf:RegionNames.TheUpperRegion}" Margin="5" /&gt;
      &lt;ContentControl prism:RegionManager.RegionName="{x:Static inf:RegionNames.TheBottomRegion}" Margin="5"/&gt;                     
     &lt;/DockPanel&gt;
  
      &lt;ContentControl prism:RegionManager.RegionName="{x:Static inf:RegionNames.TheWholeRegion}" Margin="5"  /&gt;
  &lt;/Grid&gt;
  </code></pre>
  
  <p>The <code>ModuleLogging</code> is loaded at first. Then if user is authenticated, I would like to load <code>ModuleItems</code>.
  As I understood correctly, I should instantiate</p>
  
  <p>My bootstrapper class:</p>
  
  <pre><code>protected override IModuleCatalog CreateModuleCatalog()
  {
     ModuleCatalog catalog = new ModuleCatalog();
     catalog.AddModule(typeof(ModuleLogging));
     //I've not added ModuleItems as I want to check whether the user is authorized
     return catalog;
  }   
  </code></pre>
  
  <p>What I've tried to call <code>ModuleItems</code> from <code>ModuleLogging</code>:</p>
  
  <pre><code>Uri viewNav = new Uri("ModuleItems", UriKind.Relative);
  regionManager.RequestNavigate(RegionNames.TheUpperRegion, viewNav);
  regionManager.RequestNavigate(RegionNames.TheBottomRegion, viewNav); 
  </code></pre>
  
  <p>But my <code>LoggingView</code> of <code>ModuleLogging</code> is not replaced by the <code>ToolBarView</code> of <code>ModuleItems</code> and <code>DockingView</code> of <code>ModuleItems</code>. I just see  <code>System.Object</code> and  <code>System.Object</code> respectively in ContentControls instead of controls as <code>LoggingView</code> is transparent.</p>
  
  <p>Yeah, I know that there is no object in memory such as <code>ModuleItems</code> .</p>
  
  <p>How to load module on demand and navigate to the views?</p>
