Question

当我在VS调试器中运行我的代码并将其设置为在抛出时捕获CLR异常时，我得到了大量的这些HttpExceptions，它们指的是“无法加载类型”，它引用了已从应用程序中删除的页面/类。它不会导致页面出现任何问题（.NET知道以某种方式忽略此异常），但它真的很烦人。

Answer 1

我在使用aspnet_compiler debugging an error时解决了这个问题。事实证明我的项目在我的网站的内容目录中有物理的.aspx文件，这些文件是从我的项目中“排除”的。因为它们被排除在外，所以它们不会抛出任何编译时错误。

出于某种原因，网页（aspx）编译构建管理器找到它们并尝试构建它们！我假设这与dll和aspx文件之间的编译分离有关。 aspnet_compiler不会检查ProjectName.vbproj（或.csproj）是否要编译哪些页面，它会编译所有页面。（如果有人能记录下来，那就太棒了！）

Answer 2

我遇到了同样的问题。它是一个ascx文件。但是，它背后的代码是一个dll。它在一台服务器上工作，但不是另一台。 DLL之间的比较显示出不一致。我们将DLL从工作版本复制到非工作版本，问题解决了。

Answer 3

我最近在Web应用程序中经历了这一点。问题是nuget程序包引入了依赖项Microsoft.Net.Compiler和Microsoft.Code.Dom

它们支持多级编译器版本。.

那将我的应用程序转换为ASP.NET网站应用程序，而不是Web应用程序..花了我一整天才能解决这2.5天！

我从Nuget Manager中删除了这些文件，删除了obj和bin目录中的文件-关闭了studio-然后重建了项目。

那是什么痛苦！
