## What it is
ClrMD (Microsoft.Diagnostics.Runtime) is a .NET library for introspecting live processes and crash dumps of .NET applications. It provides APIs to inspect managed heaps, threads, stacks, and runtime state, enabling tools similar to SOS and PSSCOR.

## Use cases
- analyze .NET crash dumps programmatically
- inspect managed heap of a live process
- build custom debugger plugins for .NET
- walk threads and call stacks of a dump
- find memory leaks by examining the GC heap
- write diagnostics tools like SOS commands in C#

## When to choose
- you need programmatic access to .NET process or dump internals
- building custom diagnostic or debugging tooling for .NET
- automating crash dump analysis in C#

## When to avoid
- debugging non-.NET native processes
- you only need simple interactive debugging (use WinDbg/SOS instead)
- targeting runtimes other than .NET/CLR

## Facets
- artifact type: library
- maturity: active
- function: developer-tools
- domain: developer-tools
- platform: windows, cross-platform, dotnet
