title: ConnectionString' is not a member of .My.MySettings' in DataSet.Designer.vb After deleting unused connectionstring
body: <p>I deleted an unused connectionstring and now I have wasted a lot of hours trying to get it back to work. Cause the rest of the program worked like a char and the connectiontring was never used I was working on another database.</p>

  <p>All the errors lead to a code that looks like </p>
  
  <pre><code>Private Sub InitConnection()
      Me._connection = New Global.System.Data.OleDb.OleDbConnection()
      Me._connection.ConnectionString = Global.GIP_Eindwerk.My.MySettings.Default.dbGIPEXConnectionString
  End Sub
  </code></pre>
  
  <p>I've tried removing</p>
  
  <pre><code>&lt;Connection AppSettingsObjectName="MySettings" AppSettingsPropertyName="dbGIPEXConnectionString" ConnectionStringObject="" IsAppSettingsProperty="true" Modifier="Assembly" Name="dbGIPEXConnectionString (MySettings)" PropertyReference="ApplicationSettings.GIP_Eindwerk.My.MySettings.GlobalReference.Default.dbGIPEXConnectionString" Provider="System.Data.OleDb" /&gt;
  </code></pre>
  
  <p>in the <code>dbGIPexdataset.xsd</code>.. Didn't change anything.
  Cleaning the project also changed nothing.</p>
