* Improve build reliability
- ensure `ResolveCustomReferences` target executes before packages are used
- `ResolveAssemblyReferences` and `ResolveAssemblyReferencesDesignTime` targets run too late
- e.g. failed builds of Microsoft.AspNetCore.WebUtilities or Microsoft.AspNetCore.Hosting when building from root
- add `GetReferenceProjectTargetPathMetadata` for ease of use as well as reliability
- avoids extra work to get existing metadata (ref/ projects execute no tasks in this target)
nit: rename `@(ReferenceProjectMetadata)` -> `@(ReferenceProjectTargetPathMetadata)`
* Ensure `GetTargetPathMetadata` target runs with `$(TargetFramework)` set
- ref/ projects all multi-target and otherwise no-op this target
* Revert "Fix various "Type or namespace not found" errors (#20736)"
- change is no longer needed with other fixes in this PR
This reverts commit 8218d6e0e7.
* Fix use of precedence in endpoint routing DFA
Fixes: #18677Fixes: #16579
This is a change to how sorting is use when building endpoint routing's graph of
nodes that is eventually transformed into the route table. There were
bugs in how this was done that made it incompatible in some niche
scenarios both with previous implementations and how we describe the
features in the abstract.
There are a wide array of cases that might have been impacted by this
bug because routing is a pattern language. Generally the bugs will involve a
catch-all, and some something that changes ordering of templates.
Issue #18677 has the simplest repro for this, the following templates
would not behave as expected:
```
a/{*b}
{a}/{b}
```
One would expect any URL Path starting with `/a` to match the first
route, but that's not what happens.
---
The change supports an opt-in via the following AppContext switch:
```
Microsoft.AspNetCore.Routing.UseCorrectCatchAllBehavior
```
Set to true to enable the correct behavior.
---
The root cause of this bug was an issue in how the algorithm used to be
build the DFA was designed. Specifically that it uses a BFS to build the
graph, and it uses an up-front one-time sort of endpoints in order to
drive that BFS.
The building of the graph has the expectation that at each level, we
will process **all** literal segments (`/a`) and then **all** parameter
segments (`/{a}`) and then **all** catch-all segments (`/{*a}`). Routing
defines a concept called *precedence* that defines the *conceptual*
order in while segments types are ordered.
So there are two problems:
- We sort based on criteria other than precedence (#16579)
- We can't rely on a one-time sort, it needs to be done at each level
(#18677)
---
The fix is to repeat the sort operation at each level and use precedence
as the only key for sorting (as dictated by the graph building algo).
We do a sort of the matches of each node *after* building the
precedence-based part of the DFA, based on the full sorting criteria, to
maintain compatibility.
* Add test
* Added some kestrel event counters
- Connection queue length - This is the amount of connections accepted and queued in the thread pool.
- Connection count - The number of connections
- Total connections - The total number of connections ever connected.
- Connection Rate - Connections per second
* Added TLS counters
- Current TLS handshakes
- Total TLS handshakes
- Failed TLS handshakes
- TLS handshake per second
* Added HTTP/2 queue length counter
* Improve the event information
- Add TLS version to handshake events
- Add HTTP version to request queue events
- Renamed HTTP/2 request queue length to http request queue
Contributes to #4769
ServerComponentRenderingTest.CanDispatchAsyncWorkToSyncContext is quarantined but since it's not running on Helix there isn't any history available for it. With all the moving
parts in the server test, it's unclear if it's a product vs test setup issue.
Authoring a more simplified test so we can track test history. Note that it's starting off as quarantined because there's no evidence that the product code isn't broken

* Improve CSharpLanguageCharacteristics.MapKeyword performance
The razor typing perf test profile I'm looking at has 156 ms of CPU cycles spent in this method, mostly in Enum.ToString()
\n\nCommit migrated from e821a4642e
* Add a scenario for measuring navigating between components
* Apply suggestions from code review

In the razor perf typing test, Accept was showing 27 ms allocating enumerators. Additionally, modified ReadWhile to only allocate if it would return a non-empty collection (and to not use the complexity introduced by using yield enumerators)\n\nCommit migrated from 27a14af36a
The razor perf test shows about 70 ms CPU of WithSpanContext is in allocation. GetAnnotation similarly is showing about 60 ms in allocation (of which this only partly improves)\n\nCommit migrated from a060f129ff
Our razor typing test measured 153 CPU ms in this method. Optimized by fewer calls to CurrentCharacter, not checking '<' twice, and uswing a switch stmt.\n\nCommit migrated from c601c2f11e
* Several changes targeted to improving perf of RazorSyntaxTree.Parse
1) Modify ParserHelpers.IsNewLine to use a switch instead of Array.IndexOf
2) Modify Tokenizer.CreateToken to take in an array of RazorDiagnostics rather than an IReadOnlyList as that was causing a ToArray call on an empty diagnostics very often (during a SyntaxFactory.Token call)
3) Modify TokenizerBackedParser.Putback to allow an IReadOnlyList as a parameter to not require creation of a reverse enumerator.
4) Cut down allocations in HtmlMarkupParser.GetParserState by:
a) Using an IReadOnlyList instead of IEnumerable to get rid of the allocations from the .any calls
b) Don't allocate while reading initial spacing
c) Inline the IsSpacingToken code so cut down on code executed and need to allocate a separate Func
5) Modify CSharpCodeParser.IsSpacingToken to now be a set of methods instead of a single method that allocates a Func. This is a very high traffic method.
6) Implement a fairly rudimentary Whitespace token cache, as they can be reused. This was based off Roslyn's SyntaxNodeCache, but simplified significantly. It's probably worth investigating whether you should more fully embrance token caching outside of whitespace.
* PR feedback and added one more optimization in LocateOwner that's been bugging me for years. Assuming all chidlren are contained within a nodes span, we can short-circuit the DFS this code was doing significantly cutting time in this method which is important as it's exercised on the main thread during typing.
* missed a space
* StringTextToSnapshot's switch to IsNewLine needed to use start as the index to begin the search, not zero.\n\nCommit migrated from 45411f7526
Wthout that fix following error on clean cmd without MBuild on path
```
eng\tools\RepoTasks\RepoTasks.csproj : error : Version 5.0.100-preview.5.20251.2 of the .NET Core SDK requires at least version 16.5.0 of MSBuild.
