Run file-based C# apps with the .NET CLI when the user explicitly wants C#/.NET code without creating a project. Use for C# language/API experiments, one-file C# apps, small multi-file C# apps composed with `#:include`/`#:exclude`, or C# file-based apps linked with `#:ref`. Do not use for language-agnostic throwaway scripts, generic computations, Python/PowerShell-style automation, full projects, or existing app integration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# File-Based C# Apps ## When to Use - Testing a C# concept, API, or language feature with a quick file-based app - Prototyping logic before integrating it into a larger project - Building a small utility from one entry-point file and a few helper `.cs` files ## When Not to Use - The user asks for a language-agnostic quick script, throwaway computation, or shell/Python/PowerShell-style automation - The user needs a full project, solution integration, or project references in an existing app - The user is working inside an existing .NET solution and wants to add code there - The app is large enough that project structure, build customization, tests, or publish configuration should live in a `.csproj` ## Inputs | Input | Required | Description | |-------|----------|-------------| | C# code or intent | Yes | The code to run, or a description of what the file-based app should do | ## Workflow ### Step 1: Check the .NET SDK version …

How to install
mdr add dotnet/skills/csharp-scripts@sha256:acc0ea3c023127dbThe line at the top of this page pins the label git:20260629.4975793, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
