title: Where to find "Enable Debugging of Unmanaged Code" to be able to edit the code while the system is running?
body: <p>In an older version of Visual Studio (Like the one at home, guess 2013), I am able to edit my code while the system is running but I can't continue (and I don't want to continue). While <em>step-ping</em> through my code, I just want to start typing and once I finish editing then to recompile.</p>
  
  <p>The advantage is that while typing I can hoover my mouse and watch values/structures of the variables and edit according. It's a nice guide sometimes, like a reminder or notes.</p>
  
  <p><strong>Why my Visual Studio 2015 prevents me from editing my code</strong>? saying:</p>
  
  <blockquote>
    <p>Changes are not allowed when unmanaged debugging is enabled</p>
  </blockquote>
  
  <p><strong>P.S</strong> my <em><a href="https://msdn.microsoft.com/en-us/library/7yty6a48.aspx" rel="noreferrer"><strong>Edit and Continue</strong></a></em> option is enabled as suggested everywhere on the internet. And there is no <em>Enable Unmanaged debugging option</em> for 2015 like suggested here for 2010 <a href="https://msdn.microsoft.com/en-us/library/tdw0c6sf(v=vs.100).aspx" rel="noreferrer"><strong>How to: Enable Debugging of Unmanaged Code</strong></a></p>
  
  <p><strong>Edit</strong>: It's a C#/C++ application. I didn't start the project from scratch and it's a huge one. I start it as Debugger and sometimes Release. Doesn't work on both (I don't care about the Release)</p>
  
  <p>How my settings under <code>Tools -&gt; Options -&gt; Debugging -&gt; General</code> look like:</p>
