c# - 多个项目的通用菜单母版页
问题描述
我目前正在一个团队中做一个 ASP.NET 项目。团队成员到处都是，所以我们为我们分配的每个不同任务创建不同的项目。但是我们希望在我们的项目中有一个通用的顶部导航菜单，我们已经为我们的通用菜单创建了母版页。我们将母版页添加为每个项目的链接，但出现错误，不允许我们继续处理 ContentPlaceHolderID。它说“在当前母版页或页面中找不到'Maincontent'”有谁能告诉我代码有什么问题吗？我正在使用带有.Net framework 4.5.2的Microsoft Visual Studio Community 2017
浏览器从 IIS 服务器预览错误
