C# 7 and .NET: Designing Modern Cross-platform Applications

By: Mark J. Price, Ovais Mehboob Ahmed Khan

Overview of this book

C# is a widely used programming language, thanks to its easy learning curve, versatility, and support for modern paradigms. The language is used to create desktop apps, background services, web apps, and mobile apps. .NET Core is open source and compatible with Mac OS and Linux. There is no limit to what you can achieve with C# and .NET Core. This Learning Path begins with the basics of C# and object-oriented programming (OOP) and explores features of C#, such as tuples, pattern matching, and out variables. You will understand.NET Standard 2.0 class libraries and ASP.NET Core 2.0, and create professional websites, services, and applications. You will become familiar with mobile app development using Xamarin.Forms and learn to develop high-performing applications by writing optimized code with various profiling techniques. By the end of C# 7 and .NET: Designing Modern Cross-platform Applications, you will have all the knowledge required to build modern, cross-platform apps using C# and .NET. This Learning Path includes content from the following Packt products: • C# 7.1 and .NET Core 2.0 - Modern Cross-Platform Development - Third Edition by Mark J. Price • C# 7 and .NET Core 2.0 High Performance by Ovais Mehboob Ahmed Khan

Designing Guidelines for .NET Core Application Performance
Index

Design principles


Developing a clean architecture adhering to the best practices adds several benefits, and application performance is one of them. We have seen many times that the technologies used behind an application are robust and powerful, but the application's performance remains unsatisfactory or poor, which is usually because of bad architecture design and investing less time on the application's design.

In this section, we will discuss a few common design principles that should be addressed when designing and developing applications in .NET Core:

  • KISS (Keep It Simple, Stupid)
  • YAGNI (You Aren't Gonna Need It)
  • DRY (Don't Repeat Yourself)
  • Separation of Concerns
  • SOLID principles
  • Caching
  • Data structures
  • Communication
  • Resource management
  • Concurrency

KISS (Keep It Simple, Stupid)

Writing cleaner code and keeping it simple always helps developers understand and maintain it in the long run. Adding needless complexity in the code does not only make it less understandable, but also hard to maintain and...
