在asp.net App_Code目录中使用Nemerle

Question

我想在ASP.NET应用程序中使用Nemerle.具体来说,将.n文件放入App_Code.

我将此添加到我的web.config system.codedom/compilers部分:

<compiler language="n;Nemerle" extension=".n" type="Nemerle.Compiler.NemerleCodeProvider, Nemerle.Compiler"/>

运行时我得到这个例外:

程序集''已经加载到另一个appdomain中.在machine.config中设置可以帮助解决此问题.

我究竟做错了什么？

我在 Visual Studio 2010 中偶尔发现一个问题。停止任何正在运行的虚拟 Web 服务器主机进程并重新启动 Visual Studio。
