Frequently Asked Questions about dotnet-run-file

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run C# code without creating a project file?▼

Run C# code directly using dotnet run file.cs, which executes scripts without requiring a project structure. This approach supports top-level statements and run-file directives like #:package and #:sdk to manage dependencies and build settings inline.

Can I pipe C# scripts into dotnet run from stdin?▼

Yes, dotnet run accepts stdin input via the dash operator: echo 'Console.WriteLine("Hello");' | dotnet run -. This enables one-liner execution and heredoc multi-line input for quick scripting workflows.

What run-file directives does dotnet run support?▼

Run-file directives include #:package to add NuGet dependencies, #:sdk to specify the .NET SDK version, and #:property to configure build properties. These directives must appear at the top of the file and tailor the build without a project file.

How do I convert a C# run file into a full project?▼

Convert a run file to a complete project by extracting the script content and directives into a proper .csproj structure with separate source files. This transition is needed when moving from quick prototyping to maintainable project workflows.

Does dotnet run file support project references?▼

Yes, the Skill manages project references through run-file directives and component support, allowing scripts to reference external assemblies and dependencies defined in the build configuration.
