 - Fix version numbers used in Blazor WASM SDK

 - Address feedback from peer review

 - Remove workaround in dotnet-watch tests

 - Testrunner to 5.0 and adding workarounds

 - Try props.in

 - net50

 - Fixup KnownFrameworkReference for integration tests

 - Resolve a few comments
- don't use repo-specific properties in shipping file
- pass `$(DefaultNetCoreTargetFramework)` into template files used in tests

 - Update src/Components/WebAssembly/Sdk/src/targets/Microsoft.NET.Sdk.BlazorWebAssembly.Current.targets

 - Update KnownFrameworkReference for template tests

 - Use DefaultNetcoreTFM

 - Undo change to props.in

 - Update src/ProjectTemplates/test/ProjectTemplates.Tests.csproj

 - Update GenerateTestProps.targets

- this is where `$(KnownAppHostPackOrFrameworkReferenceTfm)` is needed

 - Update src/ProjectTemplates/test/ProjectTemplates.Tests.csproj

- additional template input not needed here

 - Other file changes

 - Rename the one net5.0 directory in the repo

 - Fixup rebase remnants

 - Use runtime and ref/ assemblies matching repo in Helix testing
- add Directory.Build.*.in files based on project template test infrastructure
- use files as import boundary where the project doesn't create its own Directory.Build.* files
- ensure `dotnet-watch` tests also use the latest runtime and ref/ assemblies

 - Switch Directory.Build.*.in files in Helix content
- ensure item manipulation is done after base items exist

nit: Fix *.in exclusion

 - Update TFM workaround to reference 5.0 instead of 3.1 (dotnet/aspnetcore#26991)

 - Make some Directory.Build.*.in settings override-able
- that is, move some properties to Directory.Build.props.in

also
- fix `Condition`s that resulted in empty Directory.Build.targets
- separate Directory.Build.empty.in
- ensure RunTests project is _not_ affected by root Directory.Build.* files

 - Update SDK

 - Set `$(DefaultNetCoreTargetFramework)` in Helix root Directory.Build.props
= `dotnet-watch` tests otherwise fail with "The TargetFramework value '' was not recognized"

 - Extend Helix Directory.Build.* workarounds
- generate Directory.Build.* files when restoring any projects
- include generated files in Helix runs needing the latest runtime
- copy generated files when testing `dotnet-watch` locally
- include generated content in Microsoft.NET.Sdk.BlazorWebAssembly.IntegrationTests test assets
  - remove duplicate settings from existing Directory.Build.* files
- ensure shared framework and targeting packs are laid out under .dotnet/ before test assets restore

 - !fixup! Remove extra end tags

 - !fixup! Don't build GenerateFiles.csproj in desktop `msbuild`

 - !fixup! Arcade uses different test targets

 - Disable `crossgen` when building for Helix runs
- make `$(CrossgenOutput)` property override-able
- use override in CI jobs that submit to other platforms
  - for now, leave the ARM64 Helix jobs alone (build on Ubuntu, run in Debian)

nits:
- correct condition for `$(GenerateCrossgenProfilingSymbols)`
- set `$(ASPNETCORE_TEST_LOG_DIR)` in every step of the Helix build jobs

 - Ensure ReadRequest type can be loaded on server. Fixes dotnet/aspnetcore#26882 (dotnet/aspnetcore#26931)

 - Enable debugging when using embedded PDBs (dotnet/aspnetcore#27107)

* Fix debug using embedded PDBs.

* Check for either debugBuild or referenced PDBs
