Siegfried Pammer	ed784f578d	Drop the cast where a lambda's natural type is all the target needs C# 10 converts a lambda's function type to System.MulticastDelegate, its base classes and its interfaces, and an expression tree's to Expression and LambdaExpression, so 'Delegate d = (Func<int, int>)((int x) => x);' names a type the language re-infers. The natural-type annotation now also marks anonymous functions, and the declaration site drops the redundant cast. The 'var' shortcut stays method-group-only on purpose: 'var' over an expression tree infers the delegate that the Expression<> wraps, which would silently turn a tree into a delegate. Discards are unaffected, since only a declaration ever unwraps - a discard offers no target type, and function types are not used in assignments to discards.

Siegfried Pammer	4b88e43882	Emit method groups with their natural type instead of delegate constructions A delegate construction site can drop the explicit 'new DelegateType(...)' only when the natural type C# assigns to the emitted method group is exactly the delegate type the IL constructs; otherwise 'var' (or a Delegate/object local's initializer) would re-infer a different type or none at all. MethodGroupNaturalType re-resolves the emitted form and decides this, mirroring the version-specific rules: C# 13 walks scopes one at a time (instance members before each extension scope) and prunes candidates with mismatched arity, violated constraints or the wrong static/instance form; C# 10 lets every candidate in every scope take part. Only System.Action/Func (or anonymous delegate) types qualify - Roslyn never infers a signature-compatible custom delegate type. CallBuilder annotates qualifying method groups; DeclareVariables uses the annotation to emit 'var' when the natural type equals the local's type, and to drop the construction (but keep the declared type) for Delegate- and object-typed locals. Sites in any other context keep the explicit construction. Generic groups retry with spelled type arguments, since a natural type requires them.

Siegfried Pammer	997b50d26b	Update resolver spec references to current C# standard numbering The resolver comments cited section numbers from the C# 4.0 spec (and a few from C# 9.0 drafts), which no longer match the published ECMA-334 standard. Renumber them against dotnet/csharpstandard draft-v11; every reference was checked against the actual section headings. The old 'better conversion from type' subclause (7.5.3.4) no longer exists as such and its rules live in 12.6.4.5-12.6.4.7, so that comment now says so instead of pointing at a dead number.

Siegfried Pammer	1c010a828e	Give dynamic member accesses a symbol for hover tooltips Dynamic member accesses and invocations carried only the member name (DynamicMemberResolveResult / DynamicInvocationResolveResult), so GetSymbol returned null and the editor emitted no reference or hover. Synthesize a member on the target type - a dynamic field for a member access, a dynamic-returning method for a member invocation - named after the accessed member and typed from the callsite delegate: each argument uses its recorded compile-time type when the binder set one (statically typed or constant arguments), dynamic otherwise, and the declaring type comes from the receiver's argument info. Route these through GetSymbol; TextTokenWriter and the hover renderer already turn an IEntity into a tooltip. The synthesized members have no metadata token, so they render a signature on hover but are not navigation targets. Assisted-by: Claude:claude-fable-5:Claude Code	2 months ago
