title: Suppress "CAxxxx" warnings in VS2015 not working?
body: <p>I'm using Visual Studio 2015 and working in C#. I want to suppress compilation warnings for the warning type <a href="http://msdn.microsoft.com/library/ms182187.aspx" rel="noreferrer">CA1303</a>, so I've set this in project <strong>Properties -> Build -> Suppress Warnings</strong>:</p>
  
  <p><a href="https://i.stack.imgur.com/mGdfJ.png" rel="noreferrer"><img src="https://i.stack.imgur.com/mGdfJ.png" alt="enter image description here"></a></p>
  
  <p>However, after cleaning the project and building again, I can still see the warnings of this type in the Error List. Do I need to do anything else to suppress warnings of a particular type?</p>
