Global Usings at The Top of Your C# File But that’s just C# sugar, we actually care in this blog post about the two using directives. It also uses a C# 9.0 target-typed new expression to create the Employee instance. It uses C# 9.0 Top-Level Statements, so there’s no Main method. Note that there is also a using directive for the System namespace that contains the Console class. To use this class in the Program.cs file, you need to add a using directive for the EmployeeManager.Model namespace like you see it in the codesnippet below. Let’s say you have created the following Employee class in a Console application, and you defined this Employee class in an Employee.cs file (Note also the nice file-scoped namespace in the code-snippet below. In this blog post you learn about another C# 10.0 feature that is called global using directives.Ĭ# 10.0 allows you to define using directives globally, so that you don’t have to write them in every file. In the previous blog post you learned about C# 10.0 file-scoped namespaces.
