IChannelReceiver Interface

Provides required functions and properties for the receiver channels.

Namespace:  System.Runtime.Remoting.Channels
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
<ComVisibleAttribute(True)> _
Public Interface IChannelReceiver _
	Inherits IChannel
'Usage
Dim instance As IChannelReceiver

The receiving side of channels must expose the IChannelReceiver interface.
