title: Changing autogenerated code in a C# Windows Forms Application project
body: <p>When you open a new C# Windows Forms Application project in Visual Studio 2008, you get a lot of autogenerated code (AssemblyInfo.cs, Resources.Designer.cs, Settings.Designer.cs, Form1.Designer.cs, Form1.resx, Program.cs).</p>
  
  <p>Beside adding components from the Toolbox to Form1.cs[Design] and code to Form1.cs, what files can you change? And how? And what files should be left as they are?</p>
  
  <p>PS: This is a vast subject, as far as I can tell. I don't expect an exhaustive answer. Any information you care to share will do. I also want to mention that I'm a C# beginner and only want the most basic information.</p>
  
  <p>PPS: In case you're thinking about answering "Search the internet" or something like that, don't. I have searched the internet and will do so again and again until I find the answers I'm looking for. I have found some useful information, but I feel I need more. I think it's likely I will get that at stackoverflow.com.</p>

  <p>Update 1: This question has been answered. I've marked the answer from sh_kamalh as accepted. I would like to mark the answers from David and Hans Passant as accepted as well, but I don't think you can mark more than one answer as the accepted one. Or can you?</p>
  
  <p>From what I can dedcue from the answers, you should never change the autogenerated code in a C# Windows Forms Application project in Visual Studio 2008. I don't understand everything in the answers, though, and may have overlooked something.</p>
  
  <p>If you don't agree with the summary right above or the answers below, feel free to add a contradictory answer. Or if you have an answer that supplement the answers below, feel free to add that answer. I'm sure there's more to be said on this subject.</p>

  <p>Update 2: It seems you can also write your own version of a C# Windows Forms Application project (see Davids answer below, which I forgot about when I wrote "Update 1"). It also seems you should start from scratch if you do.</p>
