title: Available Prism Region controls
body: <p>I'm new to Prism, and I tend to just do as in the samples I see; place the Regions inside an <em>ItemsControl</em>. I have read that more controls can be used for defining region, but not all. However, I haven't seen an overview on what controls can be used to define Prism regions and not. Is there a rule or a list to it? </p>
  
  <pre><code>&lt;ItemsControl x:Name="MainRegion" Regions:RegionManager.RegionName="MainRegion" /&gt;
  </code></pre>
