Gain the skills needed to solve real-world software programming problems to quickly deliver reliable applications that realize the quality goals of Agile development. In this training course, you will identify and apply the most modern of design patterns and architectures available for .NET – from lazy singletons to asynchronous adapters. Following a "separation of concerns" approach, write C# code that is much more maintainable, flexible and resilient.

You Will Learn How To

  • Solve complex programming problems using design patterns
  • Deliver bug-free code using test-driven development in Visual Studio
  • Create layered architectures for reusability and to eliminate functional duplication
  • Apply the S.O.L.I.D. principles for better class design
