WCF includes predefined bindings for most common communication protocols such as SOAP over HTTP, SOAP over TCP, and SOAP over Message Queues, etc. Interaction between WCF endpoint and client is done using a SOAP envelope. SOAP envelopes are in simple XML form, which makes WCF platform-independent.
It operates over TCP and UDP port 3702 and uses IP multicast address 239.255.255.250 or ff02::c. As the name suggests, the actual communication between nodes is done using web services standards, notably SOAP-over-UDP. Various components in Microsoft's Windows Vista operating system use WS-Discovery, e.g. "People near me".
The .NET Remoting runtime hosts the listener for requests to the object in the appdomain of the server application. On the client end, any requests to the remotable object are proxied by the .NET Remoting runtime over Channel objects, that encapsulate the actual transport mode, including TCP streams, HTTP streams and named pipes.
The WCF service has the concept of endpoints. A WCF service provides endpoints which client applications can use to communicate with the WCF service. The answer to these above questions is what is known as the ABC of WCF services and in fact are the main components of a WCF service. So let's tackle each question one by one. Address: Like a ...
WCF programming model unifies Web Services, .NET Remoting, Distributed Transactions, and Message Queues into a single Service-oriented architecture model for distributed computing, where a server exposes a service via an interface, defined using XML, to which clients connect. WCF runs in a sandbox and provides the enhanced security model all ...
Distributed Component Object Model (DCOM) is a proprietary Microsoft technology for communication between software components on networked computers.DCOM, which originally was called "Network OLE", extends Microsoft's COM, and provides the communication substrate under Microsoft's COM+ application server infrastructure.
It is not enabled by default in the pre-Service Pack 1 version of Windows Vista, but enabled in SP1 and Windows Server 2008. It uses a different algorithm to modify the congestion window – borrowing from TCP Vegas and TCP New Reno. For every acknowledgement received, it increases the congestion window more aggressively, thus reaching the peak ...
WSE 3.0 is wire-level interoperable over HTTP with Windows Communication Foundation (WCF) and supports the same version of the WS-* specifications as WCF (WS-Security 1.1, SOAP 1.2, MTOM). [4] WSE stopped receiving updates, as the latest version (WSE 3.0) was supported [1] with the Lifecycle of .NET Framework 2.0 (whose support ended on July 12 ...
