C# 9 - Top-Level Statements

C# requires a lot of boilerplate code even for simple console applications. We need a namespace, a Program class, and even a static Main method. How brilliant would it be if we could create a new file and start writing our code? C# 9 introduces top-level statements. Top-level statements allow us to write C# statements without explicitly creating a namespace, a class, and a static Main method as an entry point to our program. Top-level statements make C# feel simpler, and they help create short example programs to demonstrate language features. Also, it should be more comfortable for beginners to learn all the language features one-by-one. Top-level statements are essentially a compiler feature. That means that even if we don't write the boilerplate code ourselves, the compiler does the work for us, and we end up with the same old structure. The only limitation I experienced while working with top-level statements is that you can only have top-level statements in a single file. Top-level statements are a compiler feature introduced in C# 9. Top-level statements allow us to write short and concise C# programs. We can either use them to demonstrate specific language features or make it simpler to get started with C#. 00:00 Introduction 00:38 Top-Level Statements 02:40 Generated IL Code 03:15 Using command-line arguments 03:52 Working with Types 04:32 Limitations 04:55 Conclusion 🔥 C#/.NET Bootcamp: The Fundamentals & more (Code FRIENDS10 for 10% OFF)* https://claudiobernasconi.ch/dotnet-c... 📌 .NET Developer Roadmap https://claudiobernasconi.ch/learn-do... 📌 YouTube Playlists: The FREE Blazor Crash Course:    • The FREE Blazor Crash Course (.NET 5) | Ge...   C# Programming:    • How to Create Modern C# Console Applications   📌 Install and Use C# 9 in Visual Studio 2019:    • Install and Use C# 9 in Visual Studio 2019...   📌 SharpLab: https://sharplab.io/ ✅ SUBSCRIBE FOR MORE VIDEOS Subscribe: 🔔 https://claudiobernasconi.ch/Subscribe 🚀 CONNECT & SUPPORT Twitter:   / chbernasconic   Blog: https://claudiobernasconi.ch Newsletter: https://claudiobernasconi.ch/newsletter CREDITS 🎵 https://www.bensound.com/ 🎵 https://www.streambeats.com/ Affiliate Link: I earn a small commission at no additional cost
