title: What is the exact role of "AspNet_SqlCacheTablesForChangeNotification"
body: <p>We have a .NET 4.5 Azure Webrole with Azure (colocated) Caching enabled. We use Entity Framework 5.0 talking to an Azure SQL database.</p>
  
  <p>We did some cleanup on our staging/testing and I noticed that the entity framework edmx file complains that </p>
  
  <p><code>Entity type 'AspNet_SqlCacheTablesForChangeNotification' is not mapped.</code></p>
  
  <p>We had also briefly experimented with SQL Sync. We don't know if it's SQL Sync or Azure caching that added that table (and any other elements?) to our database</p>
  
  <p>What installs and uses <code>AspNet_SqlCacheTablesForChangeNotification</code>? Is it safe to remove it? Finally, any extra items that ride along with that table that we should cleanup?</p>
