Summary

  • Hot reload now skips an edited method or getter of a non-partial type, with a reason, when its body uses an internal member of a type the reload was not given in a place the patched method cannot reach. That covers a bare name, a lambda, local function, anonymous method, query, iterator or async method, and a body that runs through a delegating shim.
  • Before, such a body was reported as Patched and then threw MethodAccessException or FieldAccessException on the first call. A bare name failed the whole file instead.
  • This extends fix: Hot reload now patches partial-type bodies that use an internal member of a type the reload was not given #3194, which applied the same rule to partial types. The partial-type rule does not change.

User Impact

  • Before: the response said the edit was live, and the first call threw from the shim assembly. A bare inherited name failed the file's shim compile, so none of the file's edits were applied.
  • After: only that method is Skipped. Its reason names the type the member is internal to and says what to do: qualify a bare name, or run uloop compile. The file's other methods are still patched.
  • Unchanged: uses that run inside the patched method keep being patched on a non-partial type, as before:
    • a field, property or method call written with its receiver;
    • a method passed as a delegate;
    • an event subscription;
    • a member named in an object initializer or a property pattern.
      The last four are now pinned end to end.

Behaviour change

Measured on the integration branch head before this change (aee6702) unless marked inferred.

(a) Bodies that broke and are now Skipped

Form Before
Lambda: static method, instance method, or next to a read of the type's own private field Patched, then MethodAccessException from the lambda's closure class (<>c or display class) in the shim assembly
Local function Patched, then MethodAccessException from the local function (g__Read)
Anonymous method Patched, then MethodAccessException from <>c.<DerivedValue__shim0>b__0_0
Iterator (3 forms) Patched, then MethodAccessException from the state machine's MoveNext
Async method Patched, then MethodAccessException from <AsyncValue__shim0>d__0.MoveNext
Getter that also has a lambda reading a private member (runs through a delegating shim) Patched, then MethodAccessException from get_DerivedProperty__shim0
Method that raises its own event (runs through a delegating shim) Patched, then MethodAccessException from RaiseDerivedEvent__shim0, called by the patched method. Measured with the plain-type branch of the guard removed (mutation m1 below), which is the old behaviour
Lambda that calls a method on an internal member's result Patched, then MethodAccessException
Lambda parameter inferred from an internal member's result Patched, then FieldAccessException
Query clause using the member; query over its result The worker emitted the body (measured). The exception is inferred: a query clause compiles to a lambda
Inherited internal method by bare name File Failed: CS0103: The name 'InternalInstanceValue' does not exist in the current context
Lambda next to a name nothing declares The worker emitted the body (measured). The file then fails in the shim compile on the unresolved name (inferred)

(b) Intended regressions: bodies that work today and are now Skipped

The worker cannot tell these from the forms in (a).

  1. A closure that works with a value whose type the worker could not resolve, even when the closure touches only public members. Measured examples:

    • var seed = new HotReloadInternalMemberHost().InternalField; Func<int> read = () => seed + 100; was Patched and returned 103.
    • Array.Exists(HotReloadInternalMemberHost.InternalHosts(), host => host.<public field> > 0) was Patched and returned 1.

    A lambda parameter inferred from such a value, and a query over it, fall in the same group. Declaring the local with its type (int seed = ...) keeps the body patched.

  2. An internal member in a query's first from source expression (or an inner join source). Measured: (from host in HotReloadInternalMemberHost.InternalHosts() select 1).Count() was Patched and returned 1. The source expression runs in the method itself, but the worker treats the whole query as a closure.

  3. A compile-time constant inside a closure, iterator, async or delegating body. Measured:

    • nameof(HotReloadInternalMemberHost.InternalField).Length in a lambda was Patched and returned 13.
    • An internal const read in a lambda was Patched and returned the edited value.

    nameof in the method's own statements is still patched (InternalFieldInsideNameof).

  4. A bare internal static name in a file that also imports the inherited type with using static. Measured: InternalStaticValue() + 100 was Patched and returned 101. Without the using static, the same body fails the file with CS0103. Qualifying the name keeps it patched. No test: this needs a fixture file of its own.

(c) A brought-back sibling file's getter gets the out-of-reach reason

This applies to every form above. For getters, the body guard runs before the sibling guard, so the getter now gets the out-of-reach reason instead of the brought-back-file reason.

  • The old reason told the user to pass the file. That does not help here: the use would still run as code of the shim assembly.
  • Methods keep the sibling reason. A partial type's sibling getter already behaved this way.
  • One test pins it: Skip_PlainSiblingBroughtBack_GetterUsingInternalMemberInsideALambda_SaysTheMemberIsInternal.

(d) Files with no baseline

The worker has no baseline for a file when:

  • there is no compile snapshot of its text, or
  • a method key appears twice in the snapshot or in the current text.

Then every existing method of the file is treated as edited and reaches the guard, so this rule can skip unedited bodies too. Inferred from the rule, not measured (no run without a baseline was made): before, those bodies were re-patched and would throw on the call; now they keep their compiled behaviour and show up as Skipped.

Why partial and plain types skip different forms

Changes

  • UnpassedInternalMemberUse records two more facts about a use. CanBePatchedInPlace keeps its value.
    • Whether it may run outside the patched method: a closure, an async or iterator body, a delegating shim, or a closure over a value the worker could not resolve.
    • Whether it is a bare-name lookup (CS0103).
  • The body guard now also runs for plain types.
    • On a plain type it skips only those two kinds of use. Every other unresolved name goes to the shim compile as before, including an internal member of another assembly reached through InternalsVisibleTo.
    • The partial-type branch is unchanged: the same CanBePatchedInPlace decision, the same reason when a name is not such a member, and the same diagnostic order.
    • A separate, rename-only commit renames the guard from PartialTypeBodyGuard to UnresolvedBodyNameGuard.
  • Reference docs:
    • The out-of-reach row of the Skipped table now covers every type. The row for a delegate, an event, and a member named in an object initializer or a property pattern stays partial-only.
    • The mechanism page now says that an internal member of a type the reload was not given cannot be rewritten to accessor delegates.
    • The generated .claude and .agents copies are regenerated.

Input space

Rows describe an edited existing method of a plain type. Getters behave the same unless noted. "Base" is aee6702.

Verification (local)

Pull requests to the integration branch do not trigger the main PR CI, so these checks were run locally.

Build and Red

  • uloop compile: 0 errors.
  • Red on aee6702, with the fixtures and tests only (before the guard change):
    • Worker: 13 failed as predicted. 12 …CannotReachIt_SaysWhy cases had the body emitted, and the sibling getter had the sibling reason. The emit pins (5 cases), the unresolved-name pin and all existing tests passed.
    • End to end: 13 failed as predicted, with the exceptions in (a). The var case passed (Patched, 103), and the 5 delegate, event, initializer and pattern cases passed.
  • Added in review: the query clause, the query over the result, the own-event method (plain and partial), and 3 look-alike forms in a test of their own. Their base was taken with the plain-type branch removed (m1): all were emitted, and the own-event end-to-end case threw as shown in (a).

Green

  • TransformWorkerPartialTypeTests 85/85 and HotReloadUnpassedInternalMemberE2ETests 67/67.
  • Both were run after the review additions and again after the rename.
  • After review, the end-to-end helpers await the async fixture method instead of blocking on it. The class passed 67/67. With m1 applied, the same 14 cases failed, and the async case failed with MethodAccessException from <AsyncValue__shim0>d__0.MoveNext(). It did not pass silently.

Mutations
Mutations ran on the code before the docs and rename commits; those commits do not change behaviour. Each mutation was applied to the committed tree, the class was run, and the file was restored with git checkout. git status was empty after each. End-to-end runs were done for m1 and m4 only. No mutation survived.

# Mutation Failed
m1 Plain types return early (the old behaviour) Worker 18: all 14 SaysWhy cases, the 3 look-alike cases, the sibling getter. E2E 14: every form in (a)
m2 Drop the bare-name check BareName
m3 Drop the outside-the-method check 13 SaysWhy cases (all but BareName), the 3 look-alike cases, the sibling getter
m4 Plain types use the partial rule (CanBePatchedInPlace) Worker 4 (delegate, event, initializer, pattern). E2E 5
m5 Skip a plain-type unresolved name that is not such a member The nothing-declares pin. E2E InternalsVisibleTo (plain)
m6 Decide a bare-name lookup by "no receiver" Initializer, pattern
m7 Drop the closure-over-an-unresolved-value check 4 plain SaysWhy cases, 1 look-alike case, and 6 existing partial and sibling tests
m8 partial types use the plain rule partial MethodPassedAsDelegate
m9 The getter path stops calling the guard 3 partial getter tests, the sibling getter, the plain getter case
m10 A delegating shim no longer counts as outside the method The getter-with-lambda and own-event cases, plain and partial

Performance
The guard adds one GetDiagnostics(span) per edited existing body of a plain type. The input was a temporary plain type with 200 methods (return n;), compiled, then every body changed to return n + 1;.

  • Method used: the Editor's worker request for that edit was captured. Two workers were built from the same response file, this change and this change with the plain-type branch removed; only the guard source differs. Both were started with --serve, given 3 warm-up requests each, then 20 interleaved pairs, with the order flipped every pair.
  • Result (two rounds):
    • Paired difference median: 26.8 ms and 22.9 ms.
    • With the guard: median 73.5 and 73.7 ms. Without: median 46.1 and 45.8 ms.
    • Both workers wrote identical output: 200 entries, 0 skipped.
    • That is about 0.12 ms per body.
  • Why not the response's Timing.AnalysisMs: it could not separate this difference on a machine under load (1-minute load 10–19).
    1. The same bytes applied twice in a row do not run the worker again (AnalysisMs 0), so every run needs --revert-all first.
    2. Switching worker builds restarts the resident worker, which adds a cold start to the first run after every switch.
    3. Even in warm blocks, the Editor-side phases moved by seconds between blocks. Two head/without pairs of blocks gave −16 ms and +497 ms, while the patch and total phases of both builds doubled.

Regression and static checks

Not covered

  1. InternalsVisibleTo members and internal extension methods in a closure: an internal member of another assembly reached through InternalsVisibleTo, and an internal extension method, are still patched and can still throw, as before.

  2. Internal constructors and indexers: their diagnostics are outside the guard's IDs.

  3. Introduced types: unchanged.

  4. Delegates, events, and initializer or pattern member names on partial types: they stay skipped there.

  5. Brought-back sibling files keep the stricter partial rule.

  6. Reason text: it lists "a method passed as a delegate", which does not apply to plain types. On a plain type the reason appears only for closure, async, iterator, delegating-shim and bare-name uses, so the text is unchanged.

  7. Internal overload behind a public overload: an internal overload hidden behind a public overload of the same name is reported with a diagnostic outside the guard's IDs (inferred: CS1503 or CS1501; a Patched response shows no diagnostic). Measured with public int Overloaded(int) and internal int Overloaded(string), calling host.Overloaded("x"):

    • In the method's own statements it is Patched and the internal overload runs.
    • Inside a lambda it is Patched, then MethodAccessException from the lambda.

    This is the same before and after this change. On partial types it is inferred to be the same; only a plain type was measured.

  8. Constants (intended regression 3): these could be reopened by treating nameof operands and constant reads as reachable. That is a possible follow-up, not part of this pull request.

  9. Nullable receiver of ?.: a nullable value type reached with ?. (S? s = ...; s?.InternalField, where S is a struct of the target assembly). The guard's receiver lookup returns nothing for a Nullable<T> receiver, so it finds no use and the body is emitted as before. Inside a closure it is inferred to be Patched and then throw on the call (the same mechanism as the measured lambda cases; this shape was not run). On a partial type the body is skipped with the generated-part reason. This is the same before and after this change.

The worker emits an edited body of a plain type that uses an internal
member of a type the reload was not given inside a lambda, local
function, anonymous method, iterator, async method or delegating getter,
or by a bare name. The patched method then throws an access exception
when called, or the bare name fails the whole file in the shim compile.

These are failing tests until the guard covers plain types: they pin the
skip with the internal-member reason, and the forms a plain type patches
today (a method passed as a delegate, an event subscription, an object
initializer, a property pattern, an explicitly typed captured local),
which must stay emitted. The fixtures gain an async method on the plain
type and an internal event on the host.
…annot reach

An edited body of a plain type that used an internal member of a type
the reload was not given inside a closure, an async or iterator method,
or a body run through a delegating shim was patched and then threw an
access exception when called, and a bare inherited name failed the whole
file in the shim compile. The guard now looks at plain types too, but
closes only those forms: a plain type still emits a body with a name the
worker cannot resolve, so a method passed as a delegate, an event, a
member named in an initializer or a pattern, and names that are not such
an internal member stay patched as before. Partial types keep their rule.
A review of the plain-type guard found forms the tests did not pin. A
query clause runs as a closure, and a method that raises its own event
runs through a delegating shim, so an internal member used there throws
once patched; they now have cases on plain types, and the own-event case
on partial types too. Three bodies would work if patched but cannot be
told from the ones that throw: a lambda that only uses an internal
member's result as a value, the first source expression of a query, and
'nameof' of an internal member inside a lambda. They move to a test of
their own that pins the skip as a deliberate choice. The plain fixture
gains a LINQ import for the query cases, and both derived fixtures gain
an event and a method that raises it.
The reference only described the out-of-reach internal-member uses for
partial types. Plain types now skip the same uses - a bare name, a use
inside a closure, an iterator or an async method, a body whose closure
works with a value hot reload could not resolve, and a body patched
through a delegating shim - so that row now covers every type. Passing
an internal method as a delegate and using an internal event stay
skipped on partial types only, and get a row of their own. The
mechanism page said every private or internal access in a closure is
rewritten to accessor delegates; it now says an internal member of a
type the reload was not given cannot be, and points to the skip.
The guard no longer looks at partial types only: it now also skips a
plain-type body whose unresolved name is an internal member the patched
method cannot reach. The old name made a reader expect a partial-only
check, so the class and the two local variables that hold its result
are named after the unresolved names they inspect. No behavior changes.

📝 Walkthrough

Walkthrough

The reload guard now evaluates internal-member uses on plain and partial types. It distinguishes bare-name lookups and uses that may run outside the patched method. Method and getter transformation decisions use this guard, with expanded fixtures, tests, and documentation.

No specific behavior failure requiring a fix before merge is established by the supplied review context.

Security Architecture Review

Security architecture risk: 🔵 Low · up to fa586

The change rejects edits that would fail access checks rather than granting reloaded code additional access. No introduced security concern was established. Interruption and concurrent reload behavior were not fully verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The demonstrated effect is a restriction on patch eligibility for existing methods and getters in the target assembly. The inspected change does not add an external caller or grant greater runtime authority; this conclusion is bounded to the changed classification and its consumers.

Trust Boundaries and Controls

  • observed — The guard distinguishes transplanted execution from closures, state machines and delegating shims, where runtime access checks can still apply. It rejects classified out-of-reach uses rather than changing those checks. Existing accessor and metadata-visibility mechanisms predate this change.

105-107: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low value

Memoize the closure scan per body and semantic model.

For each qualifying diagnostic, FindOrNull can rescan the closure expressions and call GetTypeInfo when RunsOutsideThePatchedMethod is false. This repeats semantic analysis in the hot-reload diagnostic loops. Keep the existing short-circuit, but share a lazily computed result across each loop. The closure result depends only on the body and semantic model; keep RunsOutsideThePatchedMethod diagnostic-specific.

The helper that calls a fixture method waited on the async one with
GetAwaiter().GetResult(). EditMode tests must not block the main thread
on a task: the fixture only awaits a completed task today, so nothing
hangs, but the rule forbids the shape itself. The call helper and the
two assertion helpers that use it are now async and awaited at every
call site.
A partial type also skips an internal member of a type the reload was
not given when the body names it in an object initializer or a property
pattern: the name has no receiver, so it is not a use the partial-type
rule lets through. A plain type patches these, so they belong in the
partial-only row, which now also says the patched member call is written
with its receiver.
