title: How to make two users interact in ASP.NET WebForms in real time
body: <p>I'll need to develop a simple system (in it's essence):</p>
  
  <p>We'll have a bunch of users, the users will have their demands. Each user will create a demand and will specify what user is responsible for the demand. When the demand sent is completed, the user that received the demand will notify this to the one who created it. Basically, it's it.</p>
  
  <p>So, for a better understanding, lets pretend there are two users (A and B): 
  <br /> </p>
  
  <ul><li>A will create a demand for B; </li><li>
  At the moment that A clicks the button to create the demand, B receives it right in his screen (without posting back the page or loading from DB in a time interval); </li><li>
  Then, B will see A's demand, will work at it and, when finished, will notify A that the demand is completed. </li></ul>
  
  <p>Is there any way to do this <b>without MVC</b>? If so, what's the name of the plugin, method or any other technology that could be used?</p>
