title: VS 2008 C# Build not showing all the errors?
body: <p>VS2008/C# newbie here.  </p>
  
  <p>If I open our project, have no code files open, and hit Build Solution it'll show about half a dozen errors.  Fine.  When I start double-clicking open the individual code files (or double click on the error line) more errors start to crop up, and not necessarily about the file that I just opened.  It seems like Build Solution is not doing a complete build.  Is this normal behavior?  We've got 4 people working on different code files in the same project and some will see different set of errors than others.  It's annoying.  Is there a setting or something we're missing?</p>
  
  <p>Edit:  Sorry I wasn't more specific. It's a Visual C# Class Library project with 19 CS files with 1 to 3 classes in each file.</p>
