Use dotnet run and pass option values to the app instead of to the run command by including them after -, as in the following example: dotnet run -file Run the dotnet build command, and then open a command prompt in the scl/bin/Debug/net6.0 folder to run the executable: dotnet build You can use any of the following ways to test while developing a command-line app: Specifies that ReadFile is the method that will be called when the root command is invoked: rootCommand.SetHandler((file) =>ĭisplays the contents of the specified file when the root command is invoked: static void ReadFile(FileInfo file) ForEach(line => Console.WriteLine(line)) Ĭreates an option named -file of type FileInfo and assigns it to the root command: var fileOption = new Option( Return await rootCommand.InvokeAsync(args) Var rootCommand = new RootCommand("Sample app for System.CommandLine") Replace the contents of Program.cs with the following code: using System.CommandLine ĭescription: "The file to read and display on the console.")

Run the following command: dotnet add package System.CommandLine -prerelease Run the following command: dotnet new console -framework net6.0 NET 6 console app project named "scl".Ĭreate a folder named scl for the project, and then open a command prompt in the new folder.
