Remarks

Server-activated object types can be either single call or singleton. If an object type is single call, a new instance of it is created each time a call from the client comes in. All calls to a singleton object are handled by one instance of that object.

Any client that knows the URI of this object can obtain a proxy for this object by registering the channel it prefers with ChannelServices and activating the object by calling new or Activator.GetObject.

It is important to note that the remote object itself is not created by the registration process. This only happens when a client attempts to call a method on the object or activates the object from the client side.

For a more detailed description of server-activated objects and remote object activation, see Activation of Remote Objects.

Constructors

WellKnownServiceTypeEntry(String, String, String, WellKnownObjectMode)	Initializes a new instance of the WellKnownServiceTypeEntry class with the given type name, assembly name, object URI, and WellKnownObjectMode.
WellKnownServiceTypeEntry(Type, String, WellKnownObjectMode)	Initializes a new instance of the WellKnownServiceTypeEntry class with the given Type, object URI, and WellKnownObjectMode.

Properties

AssemblyName	Gets the assembly name of the object type configured to be a remote-activated type. (Inherited from TypeEntry)
ContextAttributes	Gets or sets the context attributes for the server-activated service type.
Mode	Gets the WellKnownObjectMode of the server-activated service type.
ObjectType	Gets the Type of the server-activated service type.
ObjectUri	Gets the URI of the well-known service type.
TypeName	Gets the full type name of the object type configured to be a remote-activated type. (Inherited from TypeEntry)

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns the type name, assembly name, object URI and the WellKnownObjectMode of the server-activated type as a String.
