Useful WCF Links for Programmers

If you are a .net professional, having at least an year of experience in application development, you might have heard about Web Services.

Continue reading if you would like to know about WCF.

WCF is a part of .NET Framework that provides a way of building service oriented applications that can communicate between objects across machines.

For example, A WCF service can serve results of a poll, live cricket scores, Stock Information..etc

I do not want to compare the WCF services with a usual web services again. Its done in hundreds of places. Here are few good links

Three Important things to know in WCF

Address - is where we communicate. URL that will be used internally to map requests and responses.

Binding - How we communicate. This is the protocol( a set of rules) that the server and client agrees and understands while communicating.

Contract - is what we communicate. There exists two types of contracts basically.

A Service Contract : specifies the operations a contract exposes, its signature, data-type, location and formats supported for communication.

A Data Contract : defines the structure and types of data exchanged in service messages. Describes the format of data, versioning system to manage changes in data

Real time Push Notifications with SignalR & PNotify (Pines Notify)

Image
In this post, let us build a small proof of concept for SignalR with two basic screens. Users.aspx: A sample user home page.Admin.aspx: This page is for administrator for sending notifications to all Users. What are we doing? Admin can make announcements. Can just post a title, a message and send it simultaneously to all the users who have opened up Users screen at that point of time.
Not a big deal? But, we are going to do that without making the Users screen to refresh to get notifications in any way. No timer is used. Users should see the notification via a live connection .Works like a call over a telephone!
