title: C# resx file error
body: <p>I'm getting a weird error with my .resx files:</p>
  
  <p>"Invalid Resx file. ResX input is not valid. Cannot find valid "resheader" tags for the ResX reader and writer type names.  C:\Documents and Settings\Users\My Documents\Visual Studio 2010\Projects\dock\WinForms\Dock\strings.resx"</p>
  
  <p>What I did was replace some files in an existing VS 2010 solution with some older ones from VS 2008 solution, most of the files work fine but I get this error and I don't know how to fix it. If it makes a difference, <a href="http://pastebay.com/146205" rel="noreferrer">here</a> is the source code of that file.</p>
  
  <p>I'm using NET WinForms 4.0, if that matters.</p>
