Preparation for Entry into .NET Bridging Program

Preparation for Entry into .NET Bridging Program In order to be successful in this program, it is important for you to have some theoretical knowledge of many concepts in software development. You should have an idea of what a database is and how it stores data. You should also be able to write a simple SQL statement to retrieve data from a table. For the C# programming part of the course it is important for you to grasp the idea of Object Oriented Programming which this PowerPoint presentation addresses. It is also important for you to know the Microsoft Windows environment and be comfortable with files, folders, copying, moving and very basic knowledge of the Office products.

Object Oriented Programming using C# If you are a complete beginner to the OOP world, please review this entire slide presentation from slide number 4 onwards. You will need to run the presentation in full-screen mode (F5) in order to hear the audio. After the presentation you may follow the links given on slide #3 to view the two videos on the official Microsoft website. For those with some exposure to OOP or to C# itself, please proceed to the videos, you may skip the slides in this presentation.

Microsoft Produced Videos Please go to this url address: http://www.microsoftvirtualacademy.com/training-courses/c-fundamentals-for-absolute-beginners Start with this video (towards the middle of the page): 15 | Understanding and Creating Classes Then watch this video: 16 | More About Classes and Methods Of course you may watch as many as you like, but we will be testing specifically on 15 and 16.
