Advanced C# Programming

Overview

In this course participants will apply C# extended features, including definitive coverage Language Integrated Query (LINQ), to streamline the use of C# as both an object-oriented and a first-class data-manipulation language.

Objectives

At the end of Advanced C# Programming training course, participants will be able to

  • Streamline data-centric applications with C# extended features and the Entity Framework (EF)
  • Integrate Microsoft Core with .NET Framework applications for high-performance data access
  • Exploit LINQ keywords and full-stack capabilities including queries, grouping and joins
  • Generate dynamic enumerations in developer-written generic classes
  • Perform Data Driven Testing in Cucumber

Prerequisites

  • Knowledge at the level of Programming in C#
