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"/>

跑步时我得到这个例外：

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这个问题。

我做错了什么？

Answer 1

我在Visual Studio 2010中发现的偶然问题。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。

看起来你缺少.config块中的一些必需属性。以下是更详细的官方常见问题解答，我没有理由在此处复制任何可能过时的过时信息：Nemerle ASP.NET FAQ

Answer 3

我也想要它，但是，App_Code文件夹用于webSite，我不知道如何让Nemerle和WebSite一起工作。目前跟踪这个想法。但是默认情况下你无法创建Nemerle webSite。

如果你正在使用Web应用程序，你可以使用名为“PinkElephant”的代码文件夹或者你想要的代码 - 它肯定会解决你的问题__ ^

在asp.net App_Code目录中使用Nemerle
