title: Nonsense errors in Visual C# Express
body: <p>I started with programming in C# with XNA framework. I have created new solution, made programm, saved it. Programm was working and no errors where there. At 2nd day when I opened solution I have had a lot of errors in one file. Code seems OK and here it is with errors in comments:</p>
