Install and use Telnet Client on Windows

This a a brief video about Telnet, a computer network communication software shipped by default with all versions of Microsoft Windows OS.
In the first section of my online [Udemy] course titled "TCP/IP Socket Programming in C# .Net for Corders & Students"  I use Telnet to connect to a TCP/IP socket server which we code as a part of the course. 
The Telnet is used only in the first section just to make things easier. Afterwards, we start working with out own custom developed client software.
This video will both explain & demonstrate how to install and run Telnet client real quick. 
You may take the course at a 50% discount through coupon code "HALF". It's a good course with hundreds of reviews and thousands of students. I got feedback from a student of distributed programming university course saying that the course had been very helpful to get him through his assignments.

Your first windows service Project

This video shows a practical example of how to create a Windows Service Project. Its taken from first section of my online [Udemy] course titled "Windows Service Programming in C# .Net For Coders & Students".

Visual Studio 2015 enterprise edition on Windows 10 is used in this example. You can do the same with older version of VS like Visual Studio 2013 or even 2010. I also show you how to rename the main service class file and explain various details. Once we build the thing successfully, we move towards next video where I show you how to add installer and other things to the Windows Service.

Differences WindowsServices Console Applications

In this video, I am going to show you the key differences between an ordinary console application and a Windows Service. The purpose of this exercise is to get you a little comfortable with the idea of Windows Services. This will make you life easier when you will need to debug these beasts as a developer, on your full time job.
I hope you're going to enjoy the video and find it useful.

What are windows services

This video attempts to explain what in the hell are Windows Service. I will also try to explain where these things are used(enterprise, banks, backed heavy lifters). I have got an extensive experience in creating Windows Services from scratch and maintaining the [dirty] code bases created by others.
When Udemy came along and my first course on TCP/IP socket programming in C# .Net took off, I thought well I know my way around Windows Services and I believe many other people will like to learn what I learned the hard way. 

That's when I started the pursuit of this course. Months of hard work based on years of industry experience is all yours for as little as $10. Grab it now!

What is a port in computer networking?

A port is like an inlet or outlet from a computer connected to a computer network, formerly known as "Host". A PC has got more than 65 thousand ports. Even your favorite smart phones be it iPhone or Android sports ports for connecting with the outer world.
Our most beloved browsers connect to the websites using http protocol through port 80. It's a standard port and it belongs to an ancient fraternity of ports known as "System Ports". No ordinary program shall use a port belonging to system ports, as long as it's not a renegade working against the system.
The apartments build example shown in this video was conceived by yours truly. I hope watching the video will give you a better understanding of how ports are used in a TCP/IP based client/server distributed system.

Windows Services and Event Logs

Short video demonstrating event viewer events created by installing and running a Windows Service.
The course can be seen here "Windows Service Programming in C# .Net For Coders & Students".

Point in showing the Windows event viewer here is to give the student a general sense of how Windows Services operate. The exercise also prepares them for debugging in future, where they might get stuck in a production scenario looking desperately for clues.
If anybody has got any questions on the subject, I'm always available to answer those.

Just by a stroke of sheer luck, I have done a lot of work on Windows services on my full time job. I show how to do it using C# .Net in this course but as a matter of fact I've created Windows Service applications using C++ as well.
That was for a thing that acted as an intermediary between NEC NEAX telephone exchange and Avaya handsets. Our thing would allow users to invoke a call recording web service from their IP phones.
