C# 14 New Feature: Script Directives

C# 14 introduces new directives that transform C# into a true scripting language. In this video, Ian Griffiths explains how the .NET 10 SDK now lets you run a single C# source file directly—no project file required.

• The shebang (#!) directive for Unix/Linux script execution
• The new #: directive for adding NuGet packages and build properties
• How these features build on the low-ceremony entry points introduced in C# 9
