title: Difference between form1.cs, form1.designer.cs and program.cs in c#
body: <p>I'm really unexperienced with c# and I'm sorry if this is to easy question, but it will help me to understand my homework better. </p>
  
  <p>I have to make some kind of c# application in Visual studio, and my main question is:
  which part of code is situated in which file: form1.cs,  form1.designer.cs  or program.cs?</p>
  
  <p>I think that Visual studio generates code in Form1.designer.cs and that I shouldn't change it unless it is neccessery, in form1.cs are function that are activated by click on some form element, and in program.cs is the main of the application. </p>
  
  <p>Am I right, and is there anything else that I should know about these files at the beginning?</p>
  
  <p>Thank you very much for your answers.</p>
