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 language skills and object oriented programming concepts (OOP).

This course concentrates on the C# programming language itself, to fully prepare delegates in readiness for using the .NET Framework/Core. No Object-Orientated knowledge is assumed. From basic procedural syntax to sophisticated object-oriented programming techniques, delegates will learn how to write .NET 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.

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

  • Write code that includes sequence, selection and iteration constructs
  • Create and use classes and structures (types), including fields, properties, methods and delegates
  • 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 classes
  • Create interfaces and apply techniques of polymorphism effectively and appropriately
  • Work with generic types
  • Leverage the power of C# features
  • Use delegates
  • Use lambda expressions in C# code
  • Use LINQ (Language Integrated Query)

In addition to the above, the following practice is introduced during the course:

  • Test-Driven Development using XUnit

Delegates must understand the fundamentals of programming. Delegates can gain this level of knowledge by attending QA's 'Programming Foundations' (QAPROGFOU) course

Please note:

  • Delegates attending this course via Extended Classroom will be required to provide dual monitors.
  • Before attending this course, 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.
