As you work programmatically with Integration Services packages, you may want to determine which roles are available to apply to packages, or to determine or set the roles applied to an individual package. The Application class of the Microsoft.SqlServer.Dts.Runtime namespace provides a variety of methods to satisfy these requirements.
Roles apply only to packages stored in the SQL Server msdb database. For more information about package roles, see Integration Services Roles (SSIS Service).
All the methods discussed in this topic require a reference to the Microsoft.SqlServer.ManagedDTS assembly. After you add the reference in a new project, import the Microsoft.SqlServer.Dts.Runtime namespace by using a using or Imports statement.
The methods of the Application class for working with the SSIS Package Store support only ".", localhost, or the server name for the local server. You cannot use "(local)".
