'Find All References' on classes that implement IDisposable in VS 2015 VB.NET does not work

Question

In VS 2015, when I click 'Find All References' on a class definition for a class that implements IDisposable, it returns MyBase.Finalize() for every class which implements IDisposable.

NOTE: This happens when I click 'Find All References' on the class definition itself (i.e. Public Class Test123). If I click 'Find All References' on the implementation (i.e. New Test123) then it only fetches instances which use that specific New constructor. This is also confusing. In VS 2010, the class definition itself and all implementations were grouped together in one list, but in 2015 they are NOT.

Refer to the screenshot below. Even when I mousehover over class Test123, it highlights the MyBase.Finalize() method for both Test123 and Test456

Visual Studio 2010 does NOT do this. Is this a bug, or a 'new feature'?

The difficulty this causes is that for the current project at work, we manually implement IDisposable for every class. So when I click 'Find All References' on any class, it takes 10-20 seconds to find the references, and then it displays thousands of instances of MyBase.Finalize() (one for every single class), and it's basically completely useless.

Screenshot (I can't directly insert pictures with my acct yet)

Public Class Form1
    Dim a As New Test123
    Dim b As New Test456
End Class

Public Class Test123
    Implements IDisposable

    Dim A As Double = 0

    'Dispose Implementation
    Dim mbDisposed As Boolean = False
    Public Overloads Sub Dispose() Implements IDisposable.Dispose
        Dispose(True)
    GC.SuppressFinalize(Me)
    End Sub
    Private Overloads Sub Dispose(ByVal lbDisposing As Boolean)
        If Not mbDisposed Then
            If lbDisposing Then
                'Dispose of all nullable objects
            End If
        End If
        mbDisposed = True
    End Sub
    Protected Overrides Sub Finalize()
        Dispose(False)
        MyBase.Finalize()
    End Sub
End Class

Public Class Test456
    Implements IDisposable

    Dim B As Double = 1

    'Dispose Implementation
    Dim mbDisposed As Boolean = False
    Public Overloads Sub Dispose() Implements IDisposable.Dispose
        Dispose(True)
        GC.SuppressFinalize(Me)
    End Sub
    Private Overloads Sub Dispose(ByVal lbDisposing As Boolean)
        If Not mbDisposed Then
            If lbDisposing Then
                'Dispose of all nullable objects
            End If
        End If
        mbDisposed = True
    End Sub
    Protected Overrides Sub Finalize()
        Dispose(False)
        MyBase.Finalize()
    End Sub
End Class

Answer 1

I downloaded Visual Studio 2017 RC. The "Find All References" window now contains a filtering combo box. If i select "Group by: Definition Only", then the actual references I'm trying to find appear in the first "group" in the list.

All the Finalize() methods from every other class in the project in the project are still listed, but they are placed in separate groups below. So technically this bug still exists, but I am able to easily filter out the garbage that I don't want to see as shown in this snapshot

Answer 2

For a given method for example, try to use "Call Hierarchy" on it to see 3 groups of calls:

1. Calls to its "base" implementation
2. Calls to its "override" implementations
3. Calls to its direct (current class) implementation
