Perform structured code reviews of C# source code covering naming conventions, performance, security, readability, and .NET best practices. Trigger phrases include "review this C# code", "check my C# for best practices", "analyze this C# class", "find issues in my C# code".

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

# Review C# Code for Best Practices

Perform a structured code review of C# source code. Identify issues related to naming conventions, performance, security, readability, and .NET best practices. Produce a prioritized report with actionable suggestions.

## Gather Context

Before reviewing, determine:

1. **Code to review** — the C# file, class, or snippet. If the user points to a file, read it. If they paste code, use it directly.
2. **Review focus** — what to prioritize:
   - `all` (default) — full review across all categories
   - `naming` — naming conventions only
   - `performance` — performance and memory only
   - `security` — security vulnerabilities only
   - `readability` — clarity, structure, and maintainability only
3. **Target framework** — the .NET version. Default to .NET 8 if not specified. Auto-detect from `<TargetFramework>` in `.csproj` if accessible.
4. **Severity threshold** — `all` (default), `warnings-and-above`, or `critical-only`.

**If context is missing:** Default to `all` focus, .NET 8, and `all` severities. Don't block the review to ask — just state your assumptions at the top of the report. Only ask if you genuinely have no code to review.

How to install

The exact contents, by fingerprint
mdr add pnp/copilot-prompts/code-review-csharp@sha256:642a8e6cb5dba3c9

The line at the top of this page pins the label git:20260218.376726b, 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.
