High-Performance Programming in C# and .NET

By: Jason Alls

Overview of this book

Writing high-performance code while building an application is crucial, and over the years, Microsoft has focused on delivering various performance-related improvements within the .NET ecosystem. This book will help you understand the aspects involved in designing responsive, resilient, and high-performance applications with the new version of C# and .NET. You will start by understanding the foundation of high-performance code and the latest performance-related improvements in C# 10.0 and .NET 6. Next, you’ll learn how to use tracing and diagnostics to track down performance issues and the cause of memory leaks. The chapters that follow then show you how to enhance the performance of your networked applications and various ways to improve directory tasks, file tasks, and more. Later, you’ll go on to improve data querying performance and write responsive user interfaces. You’ll also discover how you can use cloud providers such as Microsoft Azure to build scalable distributed solutions. Finally, you’ll explore various ways to process code synchronously, asynchronously, and in parallel to reduce the time it takes to process a series of tasks. By the end of this C# programming book, you’ll have the confidence you need to build highly resilient, high-performance applications that meet your customer's demands.

Setting up our in-memory sample data

You will be studying LINQ performance, therefore, you are going to need a collection to work with. You will work with a collection of Person objects. Each person will be named from the Greek alphabet. A Person object will consist of a FirstName, LastName, and FullName property. The FullName property will be an interpolated string that combines the first and last name of the person.

Let us now begin coding our LINQ coding combined with benchmarking, so that we can measure the performance of our LINQ statements:

  1. Create a new .NET 6.0 console application called CH07_LinqPerformance.
  2. Install the NuGet package BenchmarkDotNet.
  3. Add the following Person struct:
    public struct Person
    {
          public string FirstName { get; set; }
          public string LastName { get; set; }
          public string FullName { get { return 
         &...
