Is it possible to have Visual Studio collapse summary sections by default

Question

Is it possible to have Visual Studio fold the summary sections of methods and classes by default? Or is there a command to fold all summary sections without folding the meth

Answer 1

You will have to use a macros. Here is a link that describes the process in details. I'm pasting a code snippet here for your convenience:

''' <summary>
''' Collapse XML comment for all code members
'''</summary>
Sub CollapseXmlComments()
    Try
        DTE.UndoContext.Open("Collapse XML comments")

        Dim ce As CodeElement2
        For Each ce In DTE.ActiveDocument.ProjectItem.FileCodeModel.CodeElements
            collapseSubmembers(ce, False)
        Next

        DTE.UndoContext.Close()
    Catch ex As Exception
        DTE.UndoContext.Close()
    End Try
End Sub

''' <summary>
''' Toggles the outline of XML comment for all code members.
'''</summary>
Sub ToggleXmlComments()
    Try
        DTE.UndoContext.Open("Toggle XML comments outline")

        'remember selection
        Dim oldAnchor, oldActive As EnvDTE.TextPoint
        Dim sel As TextSelection = CType(DTE.ActiveDocument.Selection, TextSelection)
        oldAnchor = sel.AnchorPoint.CreateEditPoint
        oldActive = sel.ActivePoint.CreateEditPoint

        Dim ce As CodeElement2
        For Each ce In DTE.ActiveDocument.ProjectItem.FileCodeModel.CodeElements
            collapseSubmembers(ce, True)
        Next

        'restore selection
        sel.MoveToAbsoluteOffset(oldAnchor.AbsoluteCharOffset) 'set active point
        sel.SwapAnchor() 'set anchor to active point
        sel.MoveToAbsoluteOffset(oldActive.AbsoluteCharOffset, True)

        DTE.UndoContext.Close()
    Catch ex As Exception
        DTE.UndoContext.Close()
    End Try
End Sub

        memberStart = ce.GetStartPoint(vsCMPart.vsCMPartWholeWithAttributes).CreateEditPoint
        commentStart = getCommentStart(memberStart.CreateEditPoint, comChars)
        commentEnd = getCommentEnd(commentStart.CreateEditPoint, comChars)
        If toggle Then
            'toggle

Works fine in VS 2010 Professional.
