title: Data reader is incompatible... member does not have corresponding column in data reader
body: <p>Using VS 2008, SQL Server 2008 and WPF 3.5, I've made some changes to my schema and updated the model.  It compiles and runs fine, until the client app calls for a specific entity and I get the following (actual names replaced):</p>
  
  <pre><code>The data reader is incompatible with the specified '&lt;Model&gt;.&lt;ViewBasedEntity&gt;'. A member of the type, '&lt;Property&gt;', does not have a corresponding column in the data reader with the same name.
  </code></pre>
  
  <p>I've searched through the services app for related entity and property names, tried renaming properties in the Table Map, Seems to be a number of others out there reporting the same error, but can't seem to find a timely answer....</p>
  
  <p>...Does anyone know how to track this down, and if so, is there a fix or methodology to follow to avoid in the future?</p>
