title: Unable to update EntityFramework models from MySQL database in Visual Studio 2015 RC
body: <p>My organization upgraded from Visual Studio 2013 to Visual Studio 2015 RC a couple months ago, and we only just now attempted to update some of our existing &quot;db-first&quot; EntityFramework models from our MySQL database. When doing so, we received the following error.</p>
  <blockquote>
  <p>An exception of type 'System.ArgumentException' occurred while attempting to update from the database. The exception message is: 'Unable to convert runtime connection string to its design-time equivalent. The libraries required to enable Visual Studio to communicate with the database for design purposes (DDEX provider) are not installed for provider 'MySql.Data.MySqlClient'.</p>
  </blockquote>
  <p>A quick SO search for this error produced <a href="https://stackoverflow.com/questions/19983270/unable-to-convert-runtime-connection-string-to-its-design-time-equivalent">this result</a> from November of 2013 (specifically in reference to VS 2013)...</p>
  <blockquote>
  <p>Apparently MySql and Visual Studio 2013 don't work together yet.</p>
  <p>Here is a link on the MySql forums: <a href="http://forums.mysql.com/read.php?174,594798,600466#msg-600466" rel="noreferrer">http://forums.mysql.com/read.php?174,594798,600466#msg-600466</a></p>
  <p>You'll probably need to wait for the next release of the MySql connector.</p>
  </blockquote>
  <p>Does that mean this is likely a comparable issue, and we just have to wait it out until a new MySql.Data client is available that is compatible with VS 2015? Or is it possible that some other cause is to blame (perhaps a bug in VS 2015 RC)?</p>
  <p>We're on the latest stable versions of Entity Framework (6.1.3), MySql.Data (6.9.6) and MySql.Data.Entity (6.9.6).</p>
  <p>Especially curious to hear if anyone else has stumbled across this issue with VS 2015 RC in particular.</p>
