title: How to properly delete and re-add Entity Data Model
body: <p>newbie to Entity Framework here.  Using VS 2010 and SQL Server 2008 express DB.</p>
  
  <p>I was having trouble refreshing an Entity Data Model after adding new tables.  So, I followed a suggestion I found here to just delete and regenerate the model.</p>
  
  <p>I get to the "Choose Your Data Connection" section of the Entity Data Model Wizard and "Save entity connection settings in Web.config as:" is checked.  However, my existing name has a 1 appended to it.  For example MyDatabaseEntities is now MyDatabaseEntities1.  Of course, I don't want the "1" appended.  I killed the existing connection string in Web.config and removed all references to that name in my solution.  Yet when I try to continue I'm presented with the following error:  </p>
  
  <p>"'MyDatabaseEntites' conflicts with an existing property name in the Application Settings.  Please choose a different name"     </p>
  
  <p>I can't find a reference to that name anywhere in the solution.  I can uncheck that option and it will continue, but it STILL won't add two of the tables in the database.  Next, I completely shut everything down, rebooted, and tried again.  This time I didn't get the error above, but two of my three new tables still do not get added to the edmx model.</p>
  
  <p>Any ideas are appreciated.  Also this seems like it's still pretty buggy even in VS2010/.NET 4.  Help restore my faith...I feel like abandoning Entity Framework at this point.  Based on my experience so far and some of the other issues posted here, I feel like I'm going to spend more time chasing Entity Framework strangeness than writing useful code.</p>
  
  <p>UPDATE:  I found a resolution.  The designer doesn't display errors.  You have have to look in the native XML (edmx file) to see the errors.
