Overview



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.

This intensive course is intended for developers who will use C# to write .NET Framework applications and who are relatively new to the C# programming language. It concentrates on the C# 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.

The course provides a starting point for delegates wishing to undertake Microsoft exam 70-483 - Programming in C# although further study is likely to be required before sitting the exam.




Prerequisites



Technical pre-requisites

Delegates must understand the fundamentals of programming
This is a course for developers


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, internal, 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 C# features
Use delegates
Understand the event handling paradigm
Use lambda expressions in C# code
Use LINQ (Language Integrated Query)
Efficiently manage resources
