How to install dotnet script

dotnet script enables you to run C# scripts (.CSX) from the .NET CLI. The only requirement is to have .NET 6 or newer installed on your machine.

You can use the following command to install dotnet-script globally:

dotnet tool install -g dotnet-scriptCode language: Bash (bash)

Then to execute a script file you simply call dotnet script <file_path> like in the example below:

dotnet script startdebugging.csxCode language: Bash (bash)

How to initialize a new dotnet script

If you are just getting started and you want to create a new dotnet script file you can use the init command to scaffold a script project.

dotnet script init startdebugging.csxCode language: Bash (bash)

This will create your script file along with the launch configuration needed to debug the script using VS Code. Note that the file name is optional and will default to main.csx if you don’t specify it.
