title: "Expression not supported" when debugging lambda expressions
body: <p>I'm trying to <a href="https://blogs.msdn.microsoft.com/visualstudioalm/2014/11/12/support-for-debugging-lambda-expressions-with-visual-studio-2015/" rel="nofollow noreferrer">debug lambda expressions with Visual Studio 2015</a> while in debug mode on an Android device. If I put</p>
  
  <pre><code>this.customerList.Where(p =&gt; p.LastName == "Doe").ToList()
  </code></pre>
  
  <p>in the <em>Watch</em> or <em>Immediate Window</em> I get</p>
  
  <blockquote>
    <p>Expression not supported.</p>
  </blockquote>
  
  <p>I'm doing this after the debugger stopped at the breakpoint. If I don't use the breakpoint I get</p>
  
  <blockquote>
    <p>The expression cannot be evaluated while in run mode. </p>
  </blockquote>
  
  <p>What I'm doing wrong?</p>
  
  <p>The options stated in <a href="https://stackoverflow.com/questions/36559399/lambda-expressions-in-immediate-window-for-vs2015">lambda expressions in immediate window for VS2015</a> are grayed out and not ticked, while in debug mode.</p>
  
  <p><strong>Edit</strong></p>
  
  <p>I tried the example code from <a href="https://stackoverflow.com/questions/42975603/expression-not-supported-when-debugging-lambda-expressions?noredirect=1#comment73047349_42975603">Tatranskymedved</a> with the same result:</p>

  <p>My guess is that debugging lambda expression is not possible with Xamarin. I tried it on device and on simulator and both are showing the same result. Another possibility would be that I have to change some debugger settings. Here I tried to disable <code>Use Fast Deployment (debug mode only)</code> and <code>Use Shared Runtime</code> without success.</p>
