Improving your C# Skills

By: Ovais Mehboob Ahmed Khan, John Callaway, Clayton Hunt, Rod Stephens

Overview of this book

This Learning Path shows you how to create high performing applications and solve programming challenges using a wide range of C# features. You’ll begin by learning how to identify the bottlenecks in writing programs, highlight common performance pitfalls, and apply strategies to detect and resolve these issues early. You'll also study the importance of micro-services architecture for building fast applications and implementing resiliency and security in .NET Core. Then, you'll study the importance of defining and testing boundaries, abstracting away third-party code, and working with different types of test double, such as spies, mocks, and fakes. In addition to describing programming trade-offs, this Learning Path will also help you build a useful toolkit of techniques, including value caching, statistical analysis, and geometric algorithms. This Learning Path includes content from the following Packt products: • C# 7 and .NET Core 2.0 High Performance by Ovais Mehboob Ahmed Khan • Practical Test-Driven Development using C# 7 by John Callaway, Clayton Hunt • The Modern C# Challenge by Rod Stephens

A clean slate

So where do we begin a new application with TDD? Starting with TDD in mind is really no different from beginning any software development project. A developer must have some idea as to the goal of the application. The basic requirements should be understood. Just as we grow our application with tests, the requirements should grow with time.

One bite at a time

How do you eat an elephant? One bite at a time.

It is a massive undertaking to try to define and develop a monolithic application all at once. If you were tasked with creating Facebook you might not know where to begin. But, if you break the application down into logical portions such as Login, User Dashboard, and News Feed, it becomes much more manageable.

Minimum Viable Product

Each definition of work should be broken down into small deliverables. The concept of a Minimum Viable Product can apply to all aspects of our code. As the requirements for the monolithic application are broken down into manageable chunks, it might...
