title: What is the difference between .aspx and .aspx.cs?
body: <p>I'm not new to programming but am new to Visual Studio, MVC, C#, ASP.NET, and EXT.NET, i.e. all of the tools I am trying to use. </p>
  
  <p>I am trying to create an Ext.Net 2.0 MVC4 project and was given a similar (in functionality) non-MVC project for reference. </p>
  
  <p>I see that this non-MVC project has .aspx and .aspx.cs files. It seems like the .aspx file basically maps to the "View" in MVC that I want to make... And the .aspx.cs file has the functions that relate to the .aspx file - so is that like the "Controller"? Though the .aspx file also has some functions that seem to not be entirely view-related...</p>
  
  <p>Could someone give me a quick overview or a place to start with this?</p>
