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.

Prerequisites

  • Delegates must understand the fundamentals of programming

Target Audience

  • This intensive course is intended for developers who will use VB.NET to write .NET Framework applications and who are relatively new to the VB.NET programming language.
  • This is a course for developers.

Please note:

  • Those delegates who are attending via either virtual or extended classroom will be required to provide either dual monitors or single monitor plus a tablet device.
  • Before attending this class delegates must have a Microsoft account (signing up one is free). The instructions on how to set up a Microsoft account can be found here.

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
