title: Problems with my code after converting from Visual studio 2013 to Visual studio 2017
body: <p>I have a project that is working correctly on Visual studio 2013 Ultimate.
  Now we have installed Visual studio 2017 Enterprise.
  When I compile and run my project on VS2017 , on several lines of code I receive a strange error message :</p>
  
  <pre><code>"Cannot obtain value of the local variable or argument because it is not
   available at this instruction pointer, possibly because it has been optimized away." 
  </code></pre>
  
  <p>What can I do  , because on VS2013 I had no problems at all.</p>
  
  <p>Thank you !</p>
