Blog post text follow-up to the build conference video announcement posted here two days ago.

We are super excited to introduce a new feature that was released as part of .NET 10 Preview 4 that makes getting started with C# easier than ever. You can now run a C# file directly using dotnet run app.cs. This means you no longer need to create a project file or scaffold a whole application to run a quick script, test a snippet, or experiment with an idea. It’s simple, intuitive, and designed to streamline the C# development experience, especially for those just getting started.

In upcoming .NET 10 previews we’re aiming to improve the experience of working with file-based apps in VS Code, with enhnanced IntelliSense for the new file-based directives, improved performance, and support for debugging. At the command line we’re exploring support for file-based apps with multiple files, and ways to make running file-based apps faster.
