 - Fixup

 - Fixup

 - Remove dotnetcliruntime, fix extension

 - Make sure dotnetcliruntime is set

 - !fixup! Remove extra `?` from URI

 - Download Runtime correlation payload

 - Move from alpine 3.9 to 3.14

- revert "Revert "Use new Hosted build pools (#36110)" (#36613)"
- this reverts commit eb6705fc

- back port of #36824 and #37077

Get `dotnet` cores on Linux / macOS (#36824)

  - follow up to 0d0103b4
  - `COMPlus*` variables were uppercased and `dotnet` ignored them on Linux / macOS
  - only upload dumps in `failed()` jobs
    - use scripts to avoid more YAML complications and avoid empty artifacts

Remove unused parameter and add requested comments (#37077)

  - `parameters.buildScript` was only ever set to its default value
  - add comments explaining the `parameters.steps` expansion
    - see https://github.com/dotnet/aspnetcore/pull/36824#pullrequestreview-764795624

- backport of #36898

Don't clear NuGet caches at all (#36898)

  - `$use_global_nuget_cache` and `$useGlobalNuGetCache` have default values in our pipelines
  - therefore, cache is always within `$(System.DefaultWorkingDirectory)` and should not exist at job start

This reverts commit f4cc3c00.

- backport of #36419
- avoid yellow builds due to `PublishBuildArtifacts@1` warnings
- always include a small file

Co-authored-by: Doug Bunting <6431421+dougbu@users.noreply.github.com>

Capture dotnet dumps
- backport of #36385
- capture `dotnet` dumps
  - builds are failing soon after `dotnet msbuild` launch
- do not upload dumps twice

nit: Remove disabled explicit component detection job

* Updates npm dependencies to their latest versions.
* Standardizes build process for our JS dependencies on webpack 5 with babel, etc.
* Updates dependencies for the auth packages to their latest versions.
* Fixes test assets so that they can be run locally.

* Clean out Ubuntu 16.04 testing
- use Ubuntu 18.04 agents for testing in Docker containers on Helix

nits:
- clean up a few old mentions of Centos and Fedora testing
- fix `%(Platform)` metadata for OSX `@(HelixAvailableTargetQueue)` items
- don't mention unused internal queues in `$(TestDependsOnPlaywright)` update of `$(SkipHelixQueues)`
- sort remaining queues alphabetically in `$(SkipHelixQueues)`

* Update branding to 2.1.28

* Bump `$(MicrosoftNETCoreAppPackageVersion)`
  - version flows into `$(MicrosoftNETCoreApp21PackageVersion)` automatically
  - cherry-picked from #30729 internal branch

* Get tests and archives working after rebranding
  - skip `SharedFxTests.BaselineTest(...)` between rebranding and baseline updates
    - previous runtime is not available in this window
  - reduce retries in `RetryHelper`
    - download will usually fail repeatedly if it fails even once
    - previous maximum duration (105 min.) was greater than the job timeout
  - avoid NETSDK1023 warnings
    - eng/targets/CSharp.Common.props adds packages removed from project
  - create archives based on one that actually exists between rebranding and baseline updates
  - mostly cherry-picked from #30729 internal branch

  nit: remove unused `GetTotalRetriesUsed()` method

* Use Ubuntu 18.04 build agents
  - set locale consistently on all platforms
    - default locale on newer agents is unloved `C.UTF-8`

* Stop using Ubuntu 14.04
  - run `locale-gen` to avoid "setlocale: LC_ALL: cannot change locale" and similar
    - needs `locales` package
  - move to still-supported Ubuntu 18.04 image
    - image needs slightly-newer `libicu60`, `clang` and `lldb` packages
    - rename Dockerfile to match
  - cherry-picked from #30729 internal branch for Ubuntu image update

  nit: set locale-related environment variables to match Python default

* Avoid KoreBuild issues when using dockerbuild.sh
  - avoid MSB4011 warnings (about repeated Directory.Build.targets imports)
    - place `$DOTNET_HOME` beside repo root, not under it
  - cherry-picked from #30729 internal branch for image update

  nits:
  - use current Docker image for 2.1 alpine
  - set `$LANGUAGE` with other locale-related environment variables

* Remove obsolete Groovy code

* Pick up latest EF sources
  - minor change shouldn't affect submodule build but best to keep up

* Improve the CDN tests
  - apply efe9b95b to similar template test
  - add debug output to CDN tests
  - back-port test reliability fix
    - based on  @javiercn's 3368ea6f / #13646 fix
    - avoid `TimeSpan` arithmetic and did not match refactoring done in 'release/3.1'
      - do not have recently-added `TimeSpan` operators in 2.1
  - skip `CdnScriptTaghelperTests` on .NET Framework
    - failures appear specific to that platform
    - leave src/Templating/test/Templates.Test/CdnScriptTagTests.cs unchanged
      - test project does not target .NET Framework

- get `buildArgs` parameter to default-build.yml template working
    - nothing uses this at the moment (now that pr-validation-temp.yml is no more)
    - but, it's documented and can be useful
- remove unused `buildScript` parameter
- remove unused project-ci.yml template

* Try some internal props

* Pass envs to dockerbuild

* Fix job name

* Re-pin

* Set env vars

* Set defaults

* Add initial support for Apple Silicon

- Add osx-arm64 runtime dependency
- Add osx-arm64 to supported rid identifiers
- Update vmImage to macOS-10.15
- Use XCode 12.2 for all macOS builds
- Add build and sign macos arm64 to CI scripts

This should build aspnetcore for osx-arm64, however
the native dependencies libuv and libe_sqlite3 will
need to be updated to have full functionality.  These
are provided by separate repos.

Enabling at this point unblocks effort to create the initial
osx-arm64 SDK.

* PR Feedback

- go back to main VS2019 queues

This reverts commit 407b623c.

- was still running in every job where explicit CD build step did not execute
    - caused consistent errors in Linux MUSL x64 (Alpine) jobs
      - error was ignored but made build failure diagnosis more difficult
    - totally redundant in test jobs

* Skip component governance for linux musl x64

* Use parameters

* jazz

- #22243
- ignore a number of artifacts/ folders that cause task warnings but don't add value
- separately, correct overuse of `$(BuildDirectory)` variable
