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

How releasing builds increases performance


Release and debug builds are two build modes provided in .NET applications. Debug mode is mostly used when we are in the process of writing code or troubleshooting errors, whereas release build mode is often used while packaging the application to deploy on production servers. When developing the deployment package, developers often miss updating the build mode to the release build, and then they face performance issues when the application is deployed:

The following table shows some differences between the debug and release modes:

Debug

Release

No optimization of code is done by the compiler

Code is optimized and minified in size when built using release mode

Stack trace is captured and thrown at the time of exception

No stack trace is captured

The debug symbols are stored

All code and debug symbols under #debug directives are removed

More memory is used by the source code at runtime

Less memory is used by the source code at runtime
