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.

Running tasks asynchronously


First, we will write a simple console application that needs to execute three methods, and execute them synchronously (one after the other).

Running multiple actions synchronously

In Visual Studio 2017, press Ctrl + Shift + N or go to File | Add | New Project....

In theNewProject dialog, in the Installed list, expand Visual C#, and select .NET Core. In the center list, select Console App (.NET Core), type the name as WorkingWithTasks, change the location to C:\Code, type the solution name as Chapter13, and then click on OK.

In Visual Studio Code, create a directory named Chapter13 with a subfolder named WorkingWithTasks, and open the WorkingWithTasks folder. In Integrated Terminal, execute the command: dotnet new console.

In both Visual Studio 2017 and Visual Studio Code, ensure that the following namespaces have been imported:

using System; 
using System.Threading; 
using System.Threading.Tasks; 
using System.Diagnostics; 
using static System.Console;

There will be...
