如何在VS 2015中使用XML IntelliSense？

Visual Studio支持 XML IntelliSense for Visual Basic(它在您键入时建议使用XML元素和属性名称).我试图使用VS 2015更新我几年前在VS 2012或2013中开始的项目.该项目使用XML,我已经设置使用XML IntelliSense.该项目在VS 2015下编译并正确运行,但XML IntelliSense无法正常工作(建议不使用元素名称).

为了尝试解决问题,我创建了以下XML文件(在My Documents中存储为Test.xml)：

<?xml version="1.0" encoding="utf-8"?>
<Root xmlns="http://www.finetime.com">
    <Parent>
        <Child>Data</Child>
    </Parent>
</Root>

我在单个表单Form1上创建了一个带有单个按钮Button1的新Windows窗体项目,并将以下XML架构添加到项目中(XSD文件显示在解决方案资源管理器中)：

<?xml version="1.0" encoding="utf-8"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="http://www.finetime.com" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://www.finetime.com">
  <xs:element name="Root">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="Parent">
          <xs:complexType>
            <xs:sequence>
              <xs:element name="Child" type="xs:string" />
            </xs:sequence>
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

Form1的代码如下所示：

Imports <xmlns:ft="http://www.finetime.com">

Public Class Form1
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim xmlPath As String = IO.Path.Combine(My.Computer.FileSystem.SpecialDirectories.MyDocuments, "Test.xml")
        Dim xmlDoc As XDocument = XDocument.Load(xmlPath)
        Dim root As XElement = xmlDoc.<ft:Root>.First
        Dim data As String = root.<ft:Parent>.<ft:Child>.Value
        MessageBox.Show(data)
    End Sub
End Class

单击按钮时,项目在MessageBox中编译,运行和显示“Data”,但不会发生XML字完成.

例如,当我键入Dim root As XElement = xmlDoc.< ft：我希望显示XML元素名称的选项以完成语句,但不会出现任何内容.我错过了一步吗？

在Roslyn重建(VS2015)下,似乎没有为VB包含XML Intellisense.这在MS Connect故障单中记录： https://connect.microsoft.com/VisualStudio/feedback/details/1085407/intellisense-not-working-with-xml-to-schema.

Posted by Kevin [MSFT] on 1/14/2015 at 9:43 AM Hi,

Thanks for the feedback. Unfortunately, this is one of the corners of
the VB IDE experience that has not yet been re-built as part of the
Roslyn project. We have a workitem on our backlog to consider
implementing this in the future.
