0xC000027B exception in store UWP app (Windows.UI.XAML)
<p>I've an C#/UWP-app in beta-release in the Microsoft App-Store. Most of the users have no problems with the App, but for one user the app is crashing on startup. You can't even see the Splash-Screen (it should be displaying a logo or color, however it is white).</p>

<p>In the eventlog this genreic event is logged:</p>

<blockquote>
  <p>0xc000027b (Windows.UI.XAML)</p>
</blockquote>

<p>The only difference is, that his Windows-10 Build differs from the other users (10.0.10240 vs 10.0.10586). However, I've collected the crashdumps ("minidumps") and tried to follow <a href="https://blogs.msdn.microsoft.com/ntdebugging/2014/01/13/debugging-a-windows-8-1-store-app-crash-dump/" rel="nofollow">this</a> tutorial.
If i try this command:</p>

<pre><code>dt &lt;Parameter[0]&gt; combase!_STOWED_EXCEPTION_INFORMATION_HEADER*
</code></pre>

<p>Windbg gives me this:</p>

<blockquote>
  <p>Memory read error (at Parameter[0])</p>
</blockquote>

<p>Actually I've integrated the hockey-sdk for automatic crash-reports, but it doesn't report me that specific crash in the dashboard.</p>

<p>How can I trace down this crash?</p>

<p><strong>Update:</strong>
I've managed to get the Call-Stack with PDE:</p>

<p>This would mean, that I've somewhere an incorrect binding?</p>
