Question

最近我一直在尝试使用Mono来托管ASP.NET MVC应用程序，当尝试运行使用Visual Studio 15构建的模板应用程序时，我收到以下错误：

System.InvalidOperationException没有进程与此关联对象

我在Nginx上使用FastCGI Mono Server，操作系统是Debian延伸。

要检查这是否是服务器配置问题，我部署了一个使用Visual Studio 13创建的网站，它可以正常运行。要设置服务器，我主要关注mono docs for nginx。

我在VS15中创建的项目遇到的第一个问题是：

找不到文件“/var/www/html/mono/bin\roslyn\csc.exe”。

所以我使用了MONO_IOMAP = all设置（不确定这是否是解决此问题的正确方法）。之后我得到了我之前提到的例外。

两个站点（使用VS13构建的工作站点和模板一个站点）都以.NET Framework 4.5为目标。我在Web.config文件中找到的唯一重大区别是这一部分（在新网站中找到）：

  <system.codedom>
    <compilers>
      <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.2.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:6 /nowarn:1659;1699;1701" />
      <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.2.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:14 /nowarn:41008 /define:_MYTYPE=\&quot;Web\&quot; /optionInfer+" />
    </compilers>
  </system.codedom>

我怀疑这个问题与VS15正在使用Roslyn编译器的事实有某种联系。非常感谢任何帮助。

仔细检查错误消息并比较VS2013 / 2015项目，您应该看到CompilerPlatform位是罪魁祸首。

Microsoft主要针对.NET设计，因此它在Mono上运行效果不佳。您可以从项目中删除它以支持Mono或完全切换到.NET Core。

Visual Studio 2015在Mono上编译了ASP.NET MVC网站模板 - System.InvalidOperationException
