我厌烦了这个错误。我寻遍了网络，并试图每一个可能的建议，这个错误我能找到。

1. 删除APP_ code，构建添加文件回来，发布。 （没有工作）

在最后，我甚至尝试在命令行中，并得到以下堆栈跟踪。

解决方案

此错误发生在我，当我试图用MSBUILD来编译项目 - 这将在Visual Studio中建立罚款，甚至会调试在我的本地浏览器。在VS的发布选项的工作，以及。但是，命令行MSBUILD是导致项目每次都报错了。

我设法在我的网站打开属性页，打开'的MSBuild选项选项卡，取消勾选允许这台precompiled网站是更新选项，然后单击回车修复在VS 2012这个问题'救所有。

I am getting fed up with this error. I have search all over the web and tried every possible suggestion to this error I could find.

1. delete app_code, build, add files back, publish. (did not work)
2. delete temporary asp.net files (did not work)

In the end I even tried the command line and get the following stacktrace.

error ASPRUNTIME: Object reference not set to an instance of an object.

解决方案

This error was occurring for me when I tried to compile the project with MSBUILD - it would build fine within Visual Studio, and would even Debug in my local browser. The Publish option within VS worked, as well. But the command-line MSBUILD was causing the project to error out every time.

I managed to fix this problem in VS 2012 by opening the Property Pages on my Website, opening the 'MSBuild Options' tab, and unchecking the 'Allow this precompiled site to be updatable' option, then hitting 'save all'.
