title: Will changing an Object signature break a WCF method call using that Object?
body: <p>If I have an object that holds the parameters for my method. I need to change the Object to have an additional property. I have full control over the server, but not over all of the clients. Will this change make those clients break?</p>
  
  <p>I am using a self-hosted service with a binary endpoint.</p>
  
  <p>I am new to WCF so my apologies if this is a silly question.</p>
