Description

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 course is intended for developers who will use C# to write .NET Framework applications and who are new to the C# programming language. This includes those currently working with Visual Basic 6.0, C or Java.

This four-day workshop concentrates on the C# programming language itself, to prepare delegates fully in readiness for exploring the .NET Framework. 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 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 and should have some existing knowledge of object oriented programming concepts. 
                                                                                                                                                                                This is a course for developers. Good Windows keyboard skills and an ability to ‘leave the mouse alone’ are an absolute necessity.

Skills

Delegates will learn how to:
                                                                                                                                                                               write efficient procedural 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
build exception-handling into methods, to create robust, user-friendly 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
define and use C# indexers
understand the role of delegates in event handling
recognise the huge role of (generic) delegates in the .NET FCL beyond event handling
use lambda expressions effectively in C# 3.0 code
make use of the major C# 3.0 feature – LINQ (Language Integrated Query)
version assemblies and know how .NET searches and loads the correct DLL’s (Appendix)
efficiently manage resources (Appendix)
see the role of Attributes in .NET as metadata that can be ‘reflected’ upon (Appendix)
