# Pull Requests Tagging If you need to tag folks on an issue or PR, you will generally want to tag the owners (not the lead) for [area](#areas) to which the change or issue is closest to. For areas which are large and can be operating system or architecture specific it's better to tag owners of [OS](#operating-systems) or [Architecture](#architectures). ## Repos This list is for this **dotnet/runtime** repo. The **dotnet/aspnetcore** repo has [its own list](https://github.com/dotnet/aspnetcore/blob/main/docs/area-owners.md). ## Areas Note: Editing this file doesn't update the mapping used by `@msftbot` for area-specific issue/PR notifications. That configuration is part of the [`fabricbot.json`](../.github/fabricbot.json) file, and many areas use GitHub teams for those notifications. If you're a community member interested in receiving area-specific issue/PR notifications, you won't appear in this table or be added to those GitHub teams, but you can create a PR that updates `fabricbot.json` to add yourself to those notifications. See [automation.md](infra/automation.md) for more information on the schema and tools used by FabricBot. | Area | Lead | Owners (area experts to tag in PRs and issues) | Notes | |------------------------------------------------|----------------------|-----------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | area-AssemblyLoader-coreclr | @agocke | @agocke @elinor-fung | | | area-AssemblyLoader-mono | @agocke | @agocke @elinor-fung | | | area-Build-mono | @lewing | @akoeplinger | | | area-Codeflow | @dotnet/dnr-codeflow | @dotnet/dnr-codeflow | Used for automated PRs that ingest code from other repos | | area-Codegen-AOT-mono | @steveisok | @kotlarmilos | | | area-CodeGen-coreclr | @JulieLeeMSFT | @BruceForstall @dotnet/jit-contrib | | | area-Codegen-Interpreter-mono | @vitek-karas | @BrzVlad @kotlarmilos | | | area-Codegen-Intrinsics-mono | @steveisok | @fanyang-mono | | | area-Codegen-JIT-mono | @steveisok | | | | area-Codegen-LLVM-mono | @steveisok | | | | area-Codegen-meta-mono | @steveisok | | | | area-CrossGen/NGEN-coreclr | @steveisok | @dotnet/crossgen-contrib | | | area-crossgen2-coreclr | @steveisok | @dotnet/crossgen-contrib | | | area-Debugger-mono | @tommcdon | @thaystg | | | area-DependencyModel | @ericstj | @dotnet/area-dependencymodel | Included: | | area-Diagnostics-coreclr | @tommcdon | @tommcdon @dotnet/dotnet-diag | | | area-Diagnostics-mono | @tommcdon | @tommcdon @mdh1418 @thaystg | | | area-EnC-mono | @tommcdon | @mikelle-rogers @thaystg | Hot Reload on WebAssembly, Android, iOS, etc . @lambdageek to consult | | area-ExceptionHandling-coreclr | @mangod9 | @janvorli | | | area-Extensions-Caching | @ericstj | @dotnet/area-extensions-caching | Consultants: @mgravell, @sebastienros | | area-Extensions-Configuration | @ericstj | @dotnet/area-extensions-configuration | Consultants: @eerhardt | | area-Extensions-DependencyInjection | @ericstj | @dotnet/area-extensions-dependencyinjection | Consultants: @halter73, @benjaminpetit | | area-Extensions-FileSystem | @jeffhandley | @dotnet/area-extensions-filesystem | | | area-Extensions-Hosting | @ericstj | @dotnet/area-extensions-hosting | Consultants: @halter73, @tratcher | | area-Extensions-HttpClientFactory | @karelz | @dotnet/ncl | | | area-Extensions-Logging | @ericstj | @dotnet/area-extensions-logging | Consultants: @brennanconroy | | area-Extensions-Options | @ericstj | @dotnet/area-extensions-options | Consultants: @eerhardt, @brennanconroy | | area-Extensions-Primitives | @ericstj | @dotnet/area-extensions-primitives | | | area-GC-coreclr | @mangod9 | @Maoni0 | | | area-GC-mono | @mangod9 | @mangod9 | @BrzVlad to consult | | area-Host | @agocke | @jeffschwMSFT @vitek-karas @vsadov | Issues with dotnet.exe including bootstrapping, framework detection, hostfxr.dll and hostpolicy.dll | | area-HostModel | @agocke | @vitek-karas | | | area-ILTools-coreclr | @JulieLeeMSFT | @BruceForstall @dotnet/jit-contrib | | | area-Infrastructure | @agocke | @jeffschwMSFT @MichaelSimons | | | area-Infrastructure-coreclr | @agocke | @jeffschwMSFT | | | area-Infrastructure-installer | @MichaelSimons | @NikolaMilosavljevic | | | area-Infrastructure-libraries | @ericstj | @dotnet/area-infrastructure-libraries | Covers:
