Steps to Reproduce:

    class Program
    {
        private readonly string _foo;

        public string Foo => _foo; // Location 1

        public string FooBar() => _foo; // Location 2
    }
  1. Set a breakpoint on Location 1 and Location 2

研究方向
Investigate the breakpoint condition evaluation code in the Roslyn debugger, likely in the expression evaluator component. Focus on how 'this' is bound for expression bodied members versus regular methods. Check if the issue is related to the synthetic property getter method not providing the same binding context. Look for existing tests or similar bug fixes in the debugger area.
