サイトでマスター ページを使用していますが、何らかの理由でマスター ページをデザイン ビューで表示できなくなりました。表示されるのは、カーソルが点滅している空白のページだけです。私は2時間以上それに取り組んでいましたが、理解できません。それでも、実行すると、すべてが見栄えも動作も優れています。私は何が欠けていますか?
Site.Master コードは次のとおりです。
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site.master.cs" Inherits="WebApplication2.SiteMaster" %>

<%--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--%>
