Locating source for 'e:\\Builds\\EntLib\\Latest\\Source\\Blocks\\Data\\Src\\Data\\Sql\\SqlDatabase.cs'. Checksum: MD5 {43 28 d1 1d 5d 3b a6 a8 15 e d3 6b 52 f5 4d 89} The file 'e:\\Builds\\EntLib\\Latest\\Source\\Blocks\\Data\\Src\\Data\\Sql\\SqlDatabase.cs' does not exist.

The debug source files settings for the active solution indicate that the debugger will not ask the user to find the file: e:\\Builds\\EntLib\\Latest\\Source\\Blocks\\Data\\Src\\Data\\Sql\\SqlDatabase.cs.

  <connectionStrings>
    <add name="ApplicationServices"
         connectionString="Data Source=version;Initial Catalog=database;Persist Security Info=True;Connect Timeout=300;User ID=myusername;Password=mypass"
         providerName="System.Data.SqlClient" />
  </connectionStrings>
