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

Creating a project in VS Code


Now that your VS Code IDE is properly installed with the C# extension enabled, you are ready to create your first project.

With VS Code open, choose Open Folder from the File menu. Choose a location that is easily accessible. Many developers will create a Development folder on the root of their drive. Whatever convention you're used to will be fine. You now need to create an MSTest project.

Create a new folder named Sample. Open the Integrated Terminal window from the View menu or by using the shortcut keys (Ctrl + `). From within the Terminal window, type dotnet new mstest and hit Enter. Now, you need to restore your packages by typing dotnet restore into the Terminal window and hitting Enter.

You should now see a file named UnitTest1.cs within the Sample folder. If you open the file, it should look something like this:

using Microsoft.VisualStudio.TestTools.UnitTesting;

namespace Sample
{
  [TestClass]
  public class UnitTest1
  {
    [TestMethod]
    public...
