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

Without a clear understanding of the problem that they are attempting to solve, it can be difficult to get started. At the very least, it is ill-advised to begin without some kind of plan.

The sooner you start to code, the longer the program will take.

– Roy Carlson, University of Wisconsin

Have you ever started a craft project without any objective in mind? How did you know what it was you were making? Did the project turn out well? If it did, you more than likely picked a direction at some point and set out to achieve a goal. You may have even had to start over or make adjustments along the way in order to complete the project.

Now, imagine starting the same craft project with the desired result defined ahead of time. Perhaps you wanted to make a drawing. Maybe you developed a set of plans. It isn't until a...
