BoundDelegateCreationExpression does not implement IMethodBindingExpression

[333fred]

Given the following VB code;

Public Class C1
    Private _handler As Action(Of Object)

    Public Sub Handler(o As Object)
    End Sub

    Public Sub SetupHandler()
        _handler = AddressOf Handler
    End Sub
End Class

We get the following Operation tree for AddressOf Handler;

IOperation tree for "AddressOf Handler"

IOperation:  (OperationKind.None) (Syntax: 'AddressOf Handler')
  Children(1): IInstanceReferenceExpression (InstanceReferenceKind.Implicit) (OperationKind.InstanceReferenceExpression, Type: C1) (Syntax: 'Handler')

This is because that AddressOf results in a BoundDelegateCreationExpression, which does not implement IMethodBindingExpression. I think the fix here is just to make it implement the interface. @AlekseyTs, does that sound correct to you?

BoundDelegateCreationExpression also takes an argument for C#. It does not seem right for it to implement just IMethodBindingExpression. We already have a tracking bug for designing the correct API for exposing this bound node.

Dupe of #20095.
