The C# Programming Training in Finland

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.

• 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

Module 1: Course Introduction

Module 2: Introduction to C#

• The .NET Framework; Compilation; The Common Language Runtime; The Common Type System

• Start using Unit Test

Module 3: Variables and Datatypes

• Comments and identifiers

Module 12: Language Integrated Query (LINQ)

• LINQ syntax
• Projections
• Deferred execution and immediate execution
• Joins and aggregations
