title: SSMS version vs SSDT version - This backend version is not supported to design database diagrams or tables
body: <p>When I ****right-click a table and select <strong>Design</strong>, I receive the error
  As seen in the attached screenshot. </p>
  
  <p><img src="https://i.stack.imgur.com/90Wg3.png" alt="SQL Server results"></p>
  
  <p>It seems that the version differs between 'select @@version'(SQl server 2016 SP1 -<strong>13.0.4001.0</strong> and what it displayed when selecting Help/About - version <strong>11.0.5388</strong></p>
  
  <p>I have tried updating SSMS, Updating Visual Studio 2017 and SSDT and nothing seems to fix the issue. If anyone know how to get the versions in sync, it would certainly save me a lot more frustration. Thank you in advance.</p>
