Properties

Connection	Gets the DbConnection object being used by the current connection support instance.
ConnectionString	Gets or sets a string representation of information required to establish a specified data source connection.
ConnectionTimeout	Gets or sets the amount of time, in seconds, to wait to establish a connection before terminating the attempt and generating a time-out error.
CurrentCommand	Gets the DbCommand object currently being used by the current connection support instance.
CurrentTransaction	Gets the DbTransaction object currently being used by the current connection support instance.
InAsyncMode	Gets a value indicating whether the connection is in an asynchronous mode.
ParentProvider	Gets the current instance of the parent service provider. (Inherited from ServiceProvider)
ProviderObject	Gets the underlying provider object for the specified connection.
ServiceProvider	Gets the global Visual Studio service provider. (Inherited from DataConnectionSupport)
Site	Gets or sets the site. (Inherited from DataSiteableServiceProvider<T>)
State	Gets the state of the data connection.
