Session Integrator provides a COM and a .NET Framework interface to grant programmatic access to an SNA network using LU0 and LU2 protocols. The following tables describe the relationships between the COM and the .NET Framework interfaces.

LU0 Interfaces

COM	.NET	Description
IcomLU0	`Microsoft.HostIntegration.SNA.Session.SessionLU0`	The primary interface for connecting, sending, and receiving information over an LU0 session.
	`Microsoft.HostIntegration.SNA.Session.SessionConnectionLU0`	Represents the LU0 connection. `SessionLU0` uses `SessionConnectionLU0` to contain the relevant connection and initialization information.
	`Microsoft.HostIntegration.SNA.Session.SessionLU0Data`	Encapsulates the information you want to send and receive over LU0. `SessionLU0` uses `SessionLU0Data` in the `Send` and `Receive` methods to send and receive data.
	`Microsoft.HostIntegration.SNA.Session.SessionLU0InitType`	Contains initialization information. `SessionLU0` uses this class during the initialization process to pass initialization information to the host.
	`Microsoft.HostIntegration.SNA.Session.SessionLU0ReceiveIndication`	Represents the current state of a session associated with a receive call.
	`Microsoft.HostIntegration.SNA.Session.SessionLU0SendIndication`	Contains values used by the `Send` method of `SessionLU0`.

LU2 Interfaces

COM	.NET	Description
	`Microsoft.HostIntegration.SNA.Session.SessionDisplay`	Provides the connection interface for the `SessionDisplay` class.
	`Microsoft.HostIntegration.SNA.Session.ScreenPosition`	Provides access to a position on the LU2 screen.
	`Microsoft.HostIntegration.SNA.Session.ScreenCursor`	Provides access to the cursor on the screen.
	`Microsoft.HostIntegration.SNA.Session.ScreenPartialField`	Provides access to a part of a screen field.
	`Microsoft.HostIntegration.SNA.Session.ScreenField`	Provides access to a particular area of the LU2 screen including the data and attributes.
	`Microsoft.HostIntegration.SNA.Session.ScreenFieldCollection`	Contains a collection of `ScreenField` classes.
	`Microsoft.HostIntegration.SNA.Session.ScreenPartialFieldCollection`	Contains a collection of `ScreenPartialFields` classes.
	`Microsoft.HostIntegration.SNA.Session.ScreenFieldAttributeData`	Provides all of the attributes about the `ScreenField` data.
Icom3270	`Microsoft.HostIntegration.SNA.Session.SessionDisplay`	Primary interface for accessing the network over a 3270 connection.
	`Microsoft.HostIntegration.SNA.Session.ScreenData`	Provides access to a particular area of the raw 3270 data representations.
	`Microsoft.HostIntegration.SNA.Session.SessionDisplayScript`	Enables users to take a script created in the Host Integration Server 3270 client and play it programmatically.
	`Microsoft.HostIntegration.SNA.Session.SessionDisplayVariableCollection`	Used with the `SessionDisplayScript` class to provide variables that can be replaced in the script.
