Visual Studio 2015在單聲道上編譯ASP.NET MVC網站模板 - System.InvalidOperationException

Question

最近，我一直在嘗試使用Mono來託管ASP.NET MVC應用程序，當試圖運行使用Visual Studio 15構建的模板應用程序時，我得到以下錯誤：

System.InvalidOperationException No process is associated with this object.

我使用FastCGI單服務器上Nginx的，操作系統是Debian的舒展。

要檢查這是否是服務器配置問題，我部署了一個使用Visual Studio 13創建的網站，它的工作原理沒有任何問題。爲了設置服務器，我主要關注mono docs for nginx。

首先的問題，我曾與VS15創建的項目是：

Could not find file "/var/www/html/mono/bin\roslyn\csc.exe".

所以我用了MONO_IOMAP =所有設定（不知道這是解決這一問題的適當辦法）。之後，我得到了我之前提到的例外情況。

兩個站點（使用VS13和模板構建的工作站）都以.NET Framework 4.5爲目標。唯一大的區別，我能找到在Web.config文件中的這一部分（在新的網站上發現）：

<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> 

我懷疑，這個問題以某種方式與事實VS15使用羅斯林編譯器相連接。任何幫助是極大的讚賞。

仔細檢查錯誤信息並比較VS2013/2015項目，您應該看到CompilerPlatform位是罪魁禍首。

微軟公司主要爲.NET設計，所以它在Mono上工作不太好。您可以將其從您的項目中移除，轉而使用Mono或完全切換到.NET Core。
