Analyzing .NET performance
Traces, dumps and allocation analysis, from the team that builds the runtime.
Installation
$ npx skills add dotnet/skillsThe CLI's unit is the repository, so this installs everything in dotnet/skills, not analyzing-dotnet-performance alone. It writes into whichever agent directories it finds — Claude Code, Codex, Cursor, Copilot, Windsurf, Zed.
Summary
Traces, dumps and allocation analysis, from the team that builds the runtime.
- Reach for it when a .NET service with a memory profile or GC pattern that needs real tooling, not guesses.
- Sits in Operate & maintain — production reality: debugging, performance, instrumentation, and writing down why the system is the way it is.
- Assumes .net.
- Published by .NET team, who ship the thing it is about — a stronger claim than a well-regarded engineer having written something good.
- Installing pulls the whole dotnet/skills repository: this catalogue lists 4 other entries from it, and the repo may hold more.

The full text lives with its publisher and changes when they change it. Read it there rather than here — a mirrored copy of somebody else's procedure goes stale silently, and this page would have no way of telling you.
