title: Documentation generation for nullable types
body: <p>There was a question about the generation of documentation by C# compiler.</p>
  
  <p>Source code:</p>
  
  <pre><code>public class SomeClass {
      /// &lt;summary&gt;
      /// Do some work
      /// &lt;/summary&gt;
      /// &lt;returns cref="Nullable{Boolean}"&gt;
      /// Some stuff
      /// &lt;/returns&gt;
      public bool? SomeMethod() {
         return false;
      }
  }
  </code></pre>
  
  <p>Compiler generated XML documentation fragment for method SomeMethod:</p>
  
  <pre><code>&lt;member name="...." &gt;
   ....
    &lt;returns cref="T:System.Nullable`1"&gt;SomeStuff&lt;/returns&gt;
  &lt;/member&gt;
  </code></pre>
  
  <p>Is there any way to force it to produce</p>
  
  <pre><code>&lt;member name="...." &gt;
   ....
    &lt;returns cref="T:System.Nullable{System.Boolean}"&gt;SomeStuff&lt;/returns&gt;
  &lt;/member&gt;
  </code></pre>
  
  <p>instead.?</p>
