title: Check VS version of a C# Project
body: <p>I have a completed C# Visual Studio project but I am not able to open it due to version issue of the Visual Studios. </p>
  
  <p>I have tried using VS2005 and VS2010, but both are unable to open the project.</p>
  
  <p>I met errors while converting the project in VS2010 as well.</p>
  
  <p>Is there any file which I could locate the version of VS used?</p>
  
  <p>__</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>Thank you for the advices.</p>
  
  <p>I have look through my csproj file as advised:</p>
  
  <p><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"&gt;</code></p>
  
  <p>From what I see, the VS ver. used is most likely to be 2003 ver.</p>
  
  <p>Please correct me if I am wrong.</p>
