The VB.NET Programming Language

Microsoft's .NET Framework presents developers with unprecedented opportunities. From web applications to desktop and mobile platform applications - all can be built with equal ease, using substantially the same skill-set. But to make the most of this potential, developers must have a thorough grasp of core language skills and OO programming concepts.


It concentrates on the programming language itself, to prepare delegates fully in readiness for exploring the .NET Framework. No Object-Orientated knowledge is assumed - the course provides a suitable OO primer. From basic procedural syntax to sophisticated object-oriented programming techniques, delegates will learn how to write .NET applications with code that is robust and maintainable.


The course is presented as a mixture of lectures, demos and hands-on exercises. Practical sessions follow all main topics, designed to reinforce the points covered. Additional information is provided in appendices to extend the learning experience after the course has been completed.


Delegates will learn how to


·       Write code that includes sequence, selection and iteration constructs

·       Create and use classes and structures (types), including fields, properties and methods

·       Use Private, Friend, Protected and Public visibility modifiers

·       Use exception-handling to create robust applications

·       Create derived classes that inherit from custom-written or .NET Framework classes

·       Create interfaces and apply techniques of polymorphism effectively and appropriately

·       Work with generic types

·       Leverage the power of VB.NET features

·       Use delegates

·       Understand the event handling paradigm

·       Use lambda expressions in code

·       Use LINQ (Language Integrated Query)

·       Efficiently manage resources
