描述

None of the descendant nodes of expression bodied property in C# returns the getter method symbol for that property when GetDeclaredSymbol is invoked on them. This seems wrong as the getter method symbol has IsImplicityDeclared = false, and also has its declaring syntax node as the ArrowExpressionClauseSyntax.

I think we want to handle GetDeclaredSymbol(ArrowExpressionClauseSyntax) to return the property getter if the given arrow expression is parented by a BasePropertyDeclarationSyntax.

研究方向
Investigate the implementation of SemanticModel.GetDeclaredSymbol in the Roslyn codebase, specifically in src/Compilers/CSharp/Portable/SemanticModel. The fix likely involves adding a case to return the property getter symbol when the ArrowExpressionClauseSyntax is parented by a BasePropertyDeclarationSyntax. No linked PRs exist, so the contribution would be from scratch.
