使用注册为allowDefinition='MachineToApplication‘的节是错误的

Question

我正在使用visual studio 2012，当我尝试发布我的web应用程序时，我得到了以下错误：

Error   1   It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level.  This error can be caused by a virtual directory not being configured as an application in IIS.  E:\Temp\BUILD\Debug\AspnetCompileMerge\Source\bin\web.config    24  0   Pixelate

下面是output窗口的内容：

如果有人能阐明为什么会发生这种情况，以及如何修复它，那就太好了。

我已经尝试了清理和重建(它重建正常)，我已经尝试删除bin，obj，并移动临时输出目录-仍然错误仍然存在。

Answer 1

这是一个问题，因为发布过程创建了额外的web.config。将鼠标悬停在web.config的选项卡上，您将看到额外文件的位置，然后可以将其清除。甚至可能是针对不同的配置，但它仍然会抛出错误(例如，调试与发布)，可能是在类似<app>\obj\Release\Package\PackageTmp\web.config的代码中。

删除它，你就可以开始工作了。不过，可能会在以后的出版中再次出现。

Answer 2

这似乎是一个非常常见的问题，当这是由Visual Studio中的Web发布功能创建的额外web.config导致时，错误消息绝对没有帮助。

通过强制我的ASP.NET应用程序项目在每次构建后清除obj目录，我能够克服这一点。

将以下内容添加到生成后事件中，并运行生成后事件：'Always‘

rmdir /S /Q "$(ProjectDir)\obj"

您的web.config中的某个设置存在问题。该错误可能会让您对位置有一个概念。
