title: Relative path on unit test project c#
body: <p>I have a solution which has a console application and unit test.</p>
  
  <pre><code>var target = new Validator();
  var targetFile = @"C:\Folder\SubFolder\AnotherSubFolder\Development\DEV\src\UnitTest\TargetFolder\file.xml";
  
  bool actual = target.Validate(targetFile);
  Assert.AreEqual(true, actual);
  </code></pre>
  
  <p>The Validator is located at the console application project, while my file.xml is located at the folder inside the unit test project.</p>
  
  <p>This unit test is passing, however i want to make sure that when i check in this in to my tfs or build server, it can still locate my targetFile.</p>
  
  <p>How am I gonna change the path of the targetFile?</p>
  
  <p>Thanks in advance!</p>
