Throw Away Bash Scripts: The Era of File-Based Apps in .NET 10

For years, Python and Bash ruled the world of DevOps scripts and quick tools. C# required a solution file, a project file, and a build process just to print "Hello World." In .NET 10, this ceremony vanishes.

This session introduces the "File-Based App" model in .NET 10. We will show how to write single-file C# programs that can reference NuGet packages, utilize the full .NET runtime, and launch instantly.

We will build:

A data migration tool using EF Core in a single .cs file.

A robust DevOps script replacing complex PowerShell logic.

A micro-web server for testing, contained entirely within app.cs.

Find out why C# is finally ready to become your favorite scripting language.
