Cursor rules for .NET
.NET rules tell Cursor your target framework, minimal-API vs MVC controllers, dependency-injection setup, and EF Core conventions. They keep generated C# matching your project structure and nullable-reference-type settings.
Every .cursorrules and .mdc file below targets .NETand is quality-scored from automated signals — freshness, schema completeness, and review activity — not star counts you can game. Each listing carries its real GitHub author and SPDX license, so you know exactly what you're pasting into your repo and under what terms. That's the difference between this and an awesome-cursor-rules link dump: here a stale or broken .NET rule sinks to the bottom instead of sitting at the top because someone starred it in 2024.
Top .NET Cursor rules by quality score
No .NET Cursor rules published yet during beta — but the catalog is filling fast. The install guide below works for any .NET rule, and you can be the first to publish one:
How to install a .NET .mdc rule
1. Pick a rule above
Open the highest quality-scored .NET listing and read the preview — make sure its conventions match your stack before you copy it.
2. Choose a location
Project-wide rules go in .cursorrules at your repo root. Scoped rules go in .cursor/rules/dotnet.mdc and attach to file globs.
3. Paste and scope it
Drop the contents in. For a .mdc file, set the frontmatter globs (e.g. globs: "**/*.ts") so Cursor auto-attaches it only for .NET files.
4. Reload Cursor
Reload the Cursor window so the rule is loaded, then confirm it appears under Settings → Rules in your active context.
# Project-wide rule
cp dotnet.cursorrules ./.cursorrules
# Or a scoped .mdc rule (auto-attaches by glob):
mkdir -p .cursor/rules
cat > .cursor/rules/dotnet.mdc <<'EOF'

EOF.NET Cursor rules — frequently asked
What's the best Cursor rule for .NET?
The best .NET Cursor rule is the one that encodes your project's conventions — not a generic one-size-fits-all file. On RuleSell, .NET rules are ranked by quality score (freshness, schema completeness, and review signals), so the top of this page is a defensible starting point. Open the highest-scored listing, then trim it to match your stack.
Where do .NET .cursorrules files go?
Put a project-wide rule in a .cursorrules file at your repo root. For scoped rules, create .cursor/rules/dotnet.mdc and attach it to the relevant file globs (for example **/*.ts) so Cursor only loads it when you're editing matching .NET files. Commit both to git so your whole team gets the same context.
Do these .NET rules work in Windsurf or Claude Code too?
Often, yes. A plain-markdown .NET rule frequently works as-is in Windsurf (rename to .windsurfrules) and as project context for Claude Code (paste into CLAUDE.md). RuleSell dual-tags listings that are verified compatible across environments.
Are these .NET Cursor rules free?
Yes — every listing is free to download during beta. Each .NET rule keeps its original GitHub author attribution and SPDX license, so you always know the provenance. Paid publishing with creator payouts opens after beta.
