如何使Razor View Engine使用C＃6.0 [英] How to make razor view engine to use c# 6.0

问题描述

当前，我的剃刀视图引擎抛出并错误提示请使用语言版本6或更高版本。那可能只是在给我一个指示。但是我如何使剃刀使用C＃6.0。我在cs文件中剩下的解决方案可以使用所有版本7的所有新功能。

Currently my razor view engine throws and error saying "Please use language version 6 or higher". That may just be resharper giving me a pointer. But how do i make razor use c# 6.0. Rest of my solution in the cs files i can use all the new version 7 features.

推荐答案

我认为这是由于项目升级到新版本的.net框架时， web.config 模板中的错误。

I believe this is due to a bug in the templates for web.config when the project is upgraded to a newer version of the .net framework.

我能够通过进入 web.config ，找到 system.codedom 节点并进行更改来解决此问题内容如下所示：

I was able to fix this by going in to web.config, finding the system.codedom node, and changing the content to look like this:

<compilers>
  <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, 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=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:14 /nowarn:41008 /define:_MYTYPE=\&quot;Web\&quot; /optionInfer+" />
</compilers>
