* Remove extra `[SkipOnHelix]` attribute
- only need the one compiled into Microsoft.AspNetCore.Testing
- update the documentation to reflect this
  - nit: address Markdown warnings that VS Code showed

* Add `SuccessfulTests` to ensure something runs in every non-Helix runs
- #22241
- cleans up hundreds of warnings but leaves a couple for the Blazor tests assembly
  - see comments about xUnit runner command line in the new class

* Add docs on HelixContent property
* Add content on Link and LinkBase attributes

* Quick fix: Simplify devBuilds.yml
  - remove an excess build step

* Quick fix: Move `SetupNugetSources` script invocations above `parameters.beforeBuild`
  - ensure NuGet.config is ready for all internal builds
  - remove now-duplicate `SetupNugetSources` invocations wherever default-build.yml is used

* Quick fix: Clean up SiteExtensions/build.cmd
  - quote all rooted paths
  - check `%ERRORLEVEL%` after every `CALL`
  - nits:
    - add a few more `ECHO` commands
    - wrap long lines

* Quick fix: Ensure `$(BuildNative)` is always set correctly
  - fix problems using `-all` or `/p:BuildAllProjects=true` without `-buildNative`
    - ensure `$(BuildNative)` is `false` where it's not supported
  - move some duplicated settings into eng/Common.props and `<Import />` the new file
  - remove now-duplicated parts of conditions using `$(BuildNative)`

* Quick fix: Consistently use `--build-*`
  - avoid `/p:Build*`  on the command line (except with eng/scripts/ci-source-build.sh)
  - nits:
    - remove now-useless `-buildNative` with `-all`
    - expand and correct a couple of related comments and messages

* Quick fix: Support `-all` together with `-projects`
  - remove need to specify `/p:BuildAllProjects=true`
  - nit: simplify some Boolean logic

* Add documentation for aspnetcore-tooling consolidation

Add short note mentioning the edition flag.

Closes https://github.com/dotnet/aspnetcore/issues/16780

This makes it easier to submit PRs and propose process changes. It also helps consolidate our documentation in the `docs/` folder.

I also updated the area list to include all of my team's areas.

* Mark AspNetCore projects that aren't packaged explicitly
- avoid NU5104 warnings due to confusing versioning
- `$(IsShippingPackage)` was semantically incorrect in any case

* Remove redundant `$(IsShippingPackage)` settings in `$(IsAspNetCoreApp)` projects
- default is `true` for all implementation projects

* Use `$(IsPackable)` when deciding how `$(IsAspNetCoreApp)` projects are handled
- remove all use of `$(IsShippingPackage)` for shared framework composition
- update documentation to match these changes

nits:
- remove odd default for `$(IsPackable)` in Directory.Build.targets
  - no longer relevant since all `$(IsAspNetCoreApp)` projects are `$(IsShippingPackage)` too
- include more information in docs/ProjectProperties.md

* Add direct System.Text.Json references
- avoid MSB3277 warnings

Also address Markdown warnings in BuildFromSource.md
- surround bare URLs with angle brackets
- add languages to code blocks
- fix missing blank lines and style inconsistencies

Except aspnet/AspNetCore-Internal.

- remove references to PatchConfig.props
- delete the file itself

Fixes https://github.com/aspnet/AspNetCore/issues/14257

- #11924
- change ci.yml to use stages and post-build.yml
  - add use of publish-build-assets.yml and post-build.yml
  - create manifests and push to artifacts in last build step of each job
    - pass more MSBuild properties into those builds
    - use Arcade to publish installers
  - use distinct `$(AssetManifestFileName)` values per job
    - set global property to override what's hard-coded in Publish.proj
- change codesign-xplat.yml to use empty.proj and normal Arcade signing and publication process
  - remove XPlatPackageSigner.proj
- change default-build.yml to use job.yml
  - remove unused parameters e.g. `matrix`, `poolName`, `variables`
  - use `enableMicrobuild` and `enablePublishTestResults` to eliminate duplicate build steps
- add .dll's and .exe's as files to sign w/ Microsoft400
  - add signcheck exclusions
- remove custom manifest generation i.e. the `GenerateBuildAssetManifest` target and related artifacts
- update docker infrastructure to use same paths in and out of the container
  - avoids problems adding to artifacts from within the builds
- correct typo in build.sh
- use `$env:DOTNET_INSTALL_DIR` in `DotNetCommands`
  - relax expectations that an arch-specific folder exists under (say) `$env:DOTNET_HOME`
  - avoids need to define `$env:DOTNET_HOME` in all jobs on CI
- update dependencies from dotnet/arcade build '20190908.2'
  - upgrade to eg. Arcade SDK '1.0.0-beta.19458.2' package version
  - pick up dotnet/arcade@dd593acc8b08 fix
    - enable use of `%(PublishFlatContainer)` metadata and correct signing validation issues
- use `$(DotNetFinalVersionKind)` in preparation for servicing builds
  - set `$(IsStableBuild)` for use in Arcade infrastructure
- disable signing validation for now (see #13864)

nits:
- upload logs in first artifact
- remove attempts to package non-existent VSIX
  - follow-up to 29cf7ecb
- respect verbosity setting in build.sh
- add more information to Artifacts.md
- enable test signing in internal PRs

Update debian arm64 Helix queue image

* Revert "Revert "Improve components infrastructure (#12145)" (#12679)"

This reverts commit e2d57e28. The improvement to components infrastructure is now reinstated with the following changes:

* Check in release JS artifacts and use them as a fallback when it's not possible to build npmproj.
* Dont' build nodejs in source build.

* Revert "Improve components infrastructure (#12145)"

This reverts commit e149f9c0.

* Update JS file

* Remove generated Web.JS javascript files files

* Build NodeJS project referenced by managed projects by default

* Build Web.JS before other CI jobs

- We can't build Web.JS on Linux Musl for example

* Make BuildAll not override explicit BuildJava/NodeJS/Native/Managed settings

* Capture CodeCheck logs for debugging

* Skip NodeJS projects when generation ref assemblies

* Do not build dependent projects if NodeJS is not built

* Make build fail immediately if BuildNodeJS is true but NodeJS is not installed

* Do not build nodejs in installer builds

Add common error 'Unable to locate the .NET Core SDK' to Build.Errors.md and BuildFromSource.md (closes #3035)

* Add Microsoft.AspNetCore.Mvc.Api.Analyzers to baselines
* also improve PreparingPatchUpdates.md
  - document changes to dependencies.props
  - reflect changes in how Templating is handled
    - e.g. use EF Core examples
  - nit: adjust indentation to avoid markdown warnings
