Repro Steps:

Add the following code to the end of the declaration of CompilationContext (i.e. inside the class) in Closed\ExpressionEvaluator\VisualBasic\Source\ExpressionCompiler\CompilationContext.vb

Friend Shared Sub Test(arg As Object)

Dim identity = If(TryCast(arg, B)?.A, TryCast(arg, A))

End Sub

Class A

End Class

Class B

Public ReadOnly Property A As A

End Class

Expected: No offer to remove cast

Actual: Offers to remove this cast.

I'm guessing it's related to the conditional access operator.
