刚刚恢复了一个我好几年没做过的旧网站。在Visual Studio中创建了一个新的ASP网站项目，并导入了所有文件。
除了一页以外，一切都很好。它总是在页面包含的内联上给我一个错误。其他页面也使用iframe，但尚未抛出错误。
该页面使用C#代码和母版页。

我试图重新创建整个页面，根据需要粘贴代码并排除原始页面。我收到第二个错误'ASP.business_wireless_payfile_aspx' does not implement interface member 'System.Web.IHttpHandler.IsReusable'`` in the temporary filec:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\21c404eb\43bc3cfb\App_Web_df3ljkuy.0.cs```
我最初尝试将此项目作为web应用程序导入，然后切换回网站。这可能是问题的一部分吗？
