If you'd prefer to use the older format, you can copy the code from the second example in this article, and continue the tutorial as before. You can imagine that the statements you write are between the open and closing braces in the Main method in the instructions of the tutorial. To follow an existing tutorial, add any new statements to the Program.cs file generated by the template. Local functions can't include any access modifiers (for example, public or protected).īoth top-level statements and implicit using directives simplify the code that makes up your application. They're created as local functions nested inside the generated Main method. You can access args (command-line arguments), use await, and set the exit code. You can add more statements to the program, just like you can add more statements to your Main method in the traditional style. You can look at the code for the new application and imagine that it contains the statements inside the Main method generated by earlier templates, but in the global namespace. The compiler generated class and Main method are declared in the global namespace. The term top-level statements means the compiler generates the class and method elements for your main program. The features that make the new program simpler are top-level statements, global using directives, and implicit using directives. If you want to use the old templates, see Use the old program style later in this article. Convert the new program style to the older style, with a Program class and a Main method.Use the new program style, adding new top-level statements as you add features.You have two options to work with tutorials that haven't been updated to use. You can learn more about the code the compiler generates when you use top level statements in the article on top level statements in the C# Guide's fundamentals section. You don't need to include the other program elements, the compiler generates them for you. The compiler synthesizes a Program class with a Main method and places all your top level statements in that Main method. When you use the newer version, you only need to write the body of the Main method. These two forms represent the same program. Namespace MyApp // Note: actual namespace depends on the project name. NET 5 and earlier versions, the console app template generates the following code: using System The new output uses recent C# features that simplify the code you need to write for a program. NET 6, the project template for new C# console apps generates the following code in the Program.cs file: // See for more information
