title: Why Visual Studio 2015 freezes crashes hangs on Designer view?
body: <p><strong><em>Everytime</em></strong> I go to the designer Visual Studio freezes(Not Responding) for 30+ seconds and once I click on any element/widget after that, it freezes again for 30+. Does that for 5 times maybe then I will be able to edit and design. </p>

  <ul>
  <li>Visual Studio in Safe Mode couldn't open most of my files. Saying this:</li>
  </ul>

  <ul>
  <li><p>I was not able to open any of the old versions in Safe Mode (for this same application) due to the same above error "<em>Unsupported</em>"</p></li>
  <li><p>I was able to create a new project in Safe Mode, and it worked fine.</p></li>
  <li><p>I was able to create a new project in Normal Mode, and it worked fine.</p></li>
  <li><p>I faced the same freezing issue when I copied/pasted the whole project into another device. So, it is something unique to my project I guess.</p></li>
  <li><p>I forgot to mention that some of the times that I go to the designer, it says <code>Invalid Markup</code> and blocks me from seeing the View until I remove these lines from the XAML:</p>
  
  <pre><code>    &lt;dxg:TableView.ColumnMenuCustomizations&gt;
          &lt;dxb:RemoveBarItemAndLinkAction ItemName="{x:Static dxg:DefaultColumnMenuItemNamesBase.ColumnChooser}" /&gt;
      &lt;/dxg:TableView.ColumnMenuCustomizations&gt;
  </code></pre></li>
  </ul>
  
  <p>It compiles and runs fine even if I keep these lines in XAML, but I can't view without removing them. And this is how one of my Views looks like if I keep them:</p>

  <p>And the underlined warning which "<em>invalidate the Markups</em>", is: </p>
  
  <blockquote>
    <p>The property "ColumnMenuCustomizations" does not have an accessible setter</p>
  </blockquote>
