类型 (System.Web.UI.WebControls.Label) 与控件类型 (ASP.controls_labelcontrol_ascx) 不兼容
type (System.Web.UI.WebControls.Label) is not compatible with the type of control (ASP.controls_labelcontrol_ascx)
以下问题与 DotNetNuke 相关 - 但在我看来是一个 asp.net 相关错误，我非常感谢解决此问题的每一个提示。
我有以下问题：在我的开发环境（Win 8.1、SqlServer 2008 R2 express、VS2013）中全新安装 DotNetNuke 7.4.2 后编辑 Html 模块的内容时显示异常最后加注。在测试环境（Win 2K8 server 64bit，SqlServer 2008 R2 express）安装7.4.2时编辑模块没有报错，一切正常。
安装是使用空数据库完成的，修改 web.config 以指向该数据库并调用 http://dnndev.me/install/install.aspx。该网站有自己的应用程序池，应用程序池用户已被授予对安装文件夹的必要权限。顺便说一句：从 DNN v4 开始，此程序已成功使用（经过修改）。
A google 搜索没有显示太多结果。我尝试清除 "v4.0.30319\Temporary ASP.NET Files" 文件夹 - 没有成功。
有谁知道这个错误的原因是什么？
谢谢你的想法，
罗伯特

站点 dnndev.me（及其应用程序）之前曾用于其他安装。
删除并重新创建站点（暗示应用程序）解决了错误（请注意，创建新的应用程序池是不够的）。
如果对此有解释，我将不胜感激。
编辑：将当前 applicationHost.config 与旧版本进行比较显示了错误的原因：有一个额外的条目指向其他旧版本中路径的完全限定名称。这导致了使用两个版本的编译（这是 Panagiotis 已经写的）。
如果您已经删除了该网站，那么现在检查可能为时已晚，但我会检查该网站下是否有 DesktopModules 上的 Application/VirtualDirectory，或中的任何子文件夹那里。这是我在 Visual Studio 中的模板的一个常见问题，出于某种原因，VS 会随机地将这些文件夹变成一个单独的应用程序，这会导致各种混乱，直到您在 IIS 中删除该应用程序。
