	Class	Description
	GlobalResourceManager	The Global Resource Manager (GRM) uses resource names to locate resources and instantiate sessions to the resources. It resolves any overlapping functionality between vendor-specific VISA.NET implementations according to user-defined criteria (with reasonable defaults). It also provides methods for parsing resource names into their constituent data items. For more information, see Resource Managers and the GRM.
	GpibControllerInChargeEventArgs	Provides additional data about a Gpib controller in charge (CIC) event.
	IOTimeoutException	A VISA.NET I/O timeout has occured.
	NativeErrorCode	The NativeErrorCode class defines constants for each of the standard VISA error status codes that may be returned by an underlying VISA C implementation.
	NativeVisaException	An error related to the underlying VISA native C implementation has occurred. The status code indicates the type of error that occurred.
	ParseResult	The detailed information derived when VISA.NET parses a resource descriptor.
	PxiInterruptEventArgs	Provides additional data about a PXI interrupt event.
	TypeFormatterException	The type formatter has encountered an error while trying to format or parse an enumeration value.
	UsbInterruptEventArgs	Provides additional data about a USB interrupt event.
	VisaConstants	VisaConstants provides access to commonly used constants.
	VisaEventArgs	Provides additional data about a VISA event.
	VisaException	VISA.NET has encountered an error.

	Interface	Description
	IGpibInterfaceSession	The session interface for a GPIB interface.
	IGpibSession	The session interface for a GPIB instrument.
	IMemoryMap	IMemoryMap is the interface that exposes memory mapped operations for register based sessions.
	IMessageBasedFormattedIO	The IMessageBasedFormattedIO interface includes methods that format and parse data to/from instrument formats, and manage the formatted I/O read and write buffers needed to do it efficiently. It correctly handles line termination and buffer flushing. When writing to an instrument, Formatted I/O makes it possible to easily send complete and correct instrument commands. When reading from an instrument, Formatted I/O makes it possible to easily read and parse complete responses. For more information, see Formatted I/O.
	IMessageBasedRawIO	The IMessageBasedRawIO interface includes methods that read and write data to/from a device without trying to format or parse it. It also is capable of performing asynchronous I/O reads and writes with a flexible set of mechanisms for notifying the calling program that the asynchronous I/O operation is complete. For more information, see Raw I/O.
	IMessageBasedSession	IMessageBasedSession is the base interface for VISA.NET message-based resources. For more information, see Resources and Sessions.
	INativeVisaEventArgs	Provides additional data about an event fired from an underlying native C event.
	INativeVisaSession	INativeVisaSession allows access to vendor-specific VISA C attributes and events. For more information, see The Native Access API.
	IPxiBackplaneSession	The session interface for a PXI backplane.
	IPxiMemorySession	The session interface for PXI memory access (MEMACC).
	IPxiSession	The session interface for a PXI instrument.
	IPxiSession2	The session interface for a PXI instrument.
	IRegisterBasedSession	IRegisterBasedSession is the base interface for VISA.NET register-based resources. For more information, see Register I/O.
	IResourceManager	The interface for finding, enumerating, and creating VISA.NET I/O resources. All VISA.NET vendor-specific resource managers derive from this interface. The VISA.NET Shared Component's resource manager doesn't derive from this interface, but provides all the members available in this interface. For more information, see Resource Managers and the GRM.
	ISerialSession	The session interface for a Serial instrument.
	ITcpipSession	The session interface for a TCP/IP instrument.
	ITcpipSession2	The session interface for a TCP/IP instrument with Secure IO.
	ITcpipSocketSession	The session interface for a TCP/IP socket session.
	ITcpipSocketSession2	The session interface for a TCP/IP socket session with secure IO.
	ITypeFormatter	The ITypeFormatter interface includes methods that perform custom conversions of supported .NET types to and from a string. It also provides a method for determining whether a particular type is supported.
	IUsbSession	The session interface for a USB instrument.
	IVisaAsyncResult	The interface that is used to communicate information about the progress and results of an asynchronous operation. The object that implements this interface specific to, and identifies, that particular operation.
	IVisaSession	IVisaSession is the base interface for VISA.NET I/O resources. It support capabilities for all resource types, specifically the lifetime management, locking, and identification. For more information, see Resources and Sessions.
	IVxiBackplaneSession	The session interface for a VXI backplane.
	IVxiMemorySession	The session interface for VXI memory access (MEMACC).
	IVxiSession	The session interface for a VXI instrument.

	Delegate	Description
	VisaAsyncCallback	The delegate for an asynchronous I/O callback argument use in the BeginRead() or BeginWrite() method calls.
