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.
Delegates looking to migrate their existing Java and/or C skills to C# should attend the QAJAVCSMIG - Migrating to C# 4.0 for Java and C developers.
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.
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
- 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
- Understand and be able to use delegates
- Understand the event handling paradigm
- Use lambda expressions effectively in C# code
- Use LINQ (Language Integrated Query)
- Efficiently manage resources
- Understand Attributes in .NET.
