IntelliSense和折叠的XML注释未按需要在designview中显示

我正在尝试为IntelliSense创建XML注释,并使用以下操作:

'''<summary>Units
''' <para>MinOccurs: '0'</para>
''' </summary>
Public Property S_Units As String = Nothing

已折叠,如下所示:

'''<summary>BinLocation
Public Property B_BinLocation As String = Nothing

我想做的是添加一个XMLcomment,当它被折叠时,它会模拟在深入研究像Microsoft这样的系统属性时它的显示方式 String.Padright 属性(我知道这只是常规评论,但需要相同的效果)

'
' Summary:
'     Returns a new string that left-aligns the characters in this string by padding
'     them on the right with a specified Unicode character, for a specified total length.
'
' Parameters:
'   totalWidth:
'     The number of characters in the resulting string, equal to the number of original
'     characters plus any additional padding characters.
'
'   paddingChar:
'     A Unicode padding character.
'
' Returns:
'     A new string that is equivalent to this instance, but left-aligned and padded
'     on the right with as many paddingChar characters as needed to create a length
'     of totalWidth. However, if totalWidth is less than the length of this instance,
'     the method returns a reference to the existing instance. If totalWidth is equal
'     to the length of this instance, the method returns a new string that is identical
'     to this instance.
'
' Exceptions:
'   T:System.ArgumentOutOfRangeException:
'     totalWidth is less than zero.
Public Function PadRight(totalWidth As Integer, paddingChar As Char) As [String]

已折叠,如下所示:

...Public Function PadRight(totalWidth As Integer) As [String]

注意椭圆与函数声明一致 如果我模拟这里使用的结构,我会得到以下结果:

'
' Summary:
'    Summary Line
'
' Returns:
'     Returns Line
Public Property S_Units As String = Nothing

导致坍塌:

' ...
Public Property S_Units As String = Nothing

请注意属性声明上方的椭圆。 值得注意的一点是,我从 System 名称空间和VS选项卡显示 String [from metadata]

这可能是它表现不同的原因吗?或者我在什么地方遗漏了一些导入或引用?

有什么我可以试试的吗?
