title: Get relative path of XML File located in another project but Same Solution
body: <p>I have found many Articles and Questions about finding an XML file but all of them are for Same Project. </p>
  
  <p>Suppose I have my Project structure as shown below:</p>
  
  <pre><code>ABC       &lt;------ Solution
  |--ABC.Data         &lt;------ Project
  |  |--XMLFiles      &lt;-------Folder
  |     |--AA.xml
  |
  |--ABC.Client      &lt;------ Project
  |  |--ViewModels   &lt;-------Folder
  |     |-MainViewModel.cs
  </code></pre>
  
  <p>Now I would like to load AA.xml file in MainViewModel.cs using <code>XDocument.Load(....path.....)</code>.</p>
  
  <p>So, how can I get <code>path</code>?</p>
