我为我的网站使用母版页，但由于某种原因，我无法再在设计视图中查看母版页。出现的只是一个带有闪烁光标的空白页。我已经玩了2个多小时了，无法弄清楚。然而，当我运行它时，一切看起来和表现都很好。我错过了什么？

这是 Site.Master 代码：

<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site.master.cs" Inherits="WebApplication2.SiteMaster" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">

<head runat="server">
<title></title>
<%--Here is where you reference your style sheets and JQuery library.  The link href takes the
    relative path and publishes fine for the directory.  With <script> and <style> tags, copies 
    like the JQuery reference, you will need to use the '<%# Page.ResolveClientUrl() %>' to get 
    the same relative path behavior at publishing time.  Typically you would define a code block
    and choose '<%=' however page headers don't play nice with code blocks.  '<%#' defines as a
    databinding expression and then when you add Page.Header.Databind() to your code behind for
    the master page, The DataBind method evaluates all the databinding expression(s) in your 
    header at load time--%>

我认为您在其中带有 ASP 标记的评论使 Visual Studio 感到困惑。尝试<%= <%# %>从您的评论中删除，看看是否有帮助。如果这是您的问题，您可能需要在标签中添加空格，以免它们混淆 VS。IE。< % =您应该仍然能够理解您的评论。
