title: ~masterurl/default.master does not exist
body: <p>I try to create a custom webpart page. I tried a book example that start with : </p>
  
  <pre><code>&lt;%@ Page MasterPageFile="~masterurl/default.master"
  Inherits="Microsoft.SharePoint.WebPartPages.WebPartPage,
            Microsoft.SharePoint, [full 4-part assembly name]"
  meta:progid="SharePoint.WebPartPage.Document" %&gt;
  </code></pre>
  
  <p>....but no result....
  The page is deployed into _layouts folder but when I try to access it from browser I get : "_layouts/~masterurl/default.master does not exist".
  What I do wrong ?</p>
  
  <p>Thank you in advance !</p>
  
  <p>Solved the problem : read again the book and indeed I did not have to add the page to _layouts folder. Thank you for opening my eyes :). All steps are well explain in the book but I was not concentrating enough. Yes, one down....</p>
