Razor syntax highlighting not working in VS 2012 with MVC 5
提问by Andreas
I'm playing around with MVC 5 RC 1 in Visual Studio 2013 RC. Works very well.
我在 Visual Studio 2013 RC 中玩弄 MVC 5 RC 1。效果很好。
Now I upgraded an existing MVC 4 project in VS 2012 to MVC 5 the same way as described here
现在，我按照此处所述的相同方式将 VS 2012 中的现有 MVC 4 项目升级到 MVC 5
I also changed the web.config(s) - see "upgrading from MVC4 to MVC5"
我还更改了 web.config(s) - 请参阅“从 MVC4 升级到 MVC5”
Everything (build, run web app, even intellisense) works perfectly except the syntax highlighting of Razor/C# code in views.
除了视图中 Razor/C# 代码的语法高亮显示之外，一切（构建、运行 Web 应用程序，甚至智能感知）都可以完美运行。
I also tried it with an MVC 5 project created in VS 2013. Same result. So I assume VS 2012 doesn't "understand" the new assemblies?!
我还使用在 VS 2013 中创建的 MVC 5 项目进行了尝试。结果相同。所以我认为 VS 2012 不“理解”新程序集？！
Any known workaround or ideas to get highlighting back?
任何已知的解决方法或想法来突出显示？

Microsoft released a new version of ASP.NET Web Tools for VS 2012. After installing syntax highlighting is back again.
Microsoft 为 VS 2012 发布了新版本的 ASP.NET Web Tools。安装语法高亮后又回来了。
Installing VS 2012 Update 4 was not enough.
安装 VS 2012 Update 4 是不够的。
A set of offline installers is available. The offline installers are easier to use than the Web Platform Tools invoker (WebNode11Pack.exe @ ~114KB):
有一组离线安装程序可用。离线安装程序比 Web 平台工具调用程序 (WebNode11Pack.exe @ ~114KB) 更易于使用：

This answerclaims that VS2012 can't understand Razor 3, so you (and me) will have to upgrade to VS2013
这个答案声称 VS2012 无法理解 Razor 3，所以你（和我）将不得不升级到 VS2013

I am currently using a workaround to get the IntelliSense working in VS2012 (I assume that this would not work properly a) if I was using VS2013 for the same project; b) if I tried using Razor 3 features):
我目前正在使用一种解决方法来让 IntelliSense 在 VS2012 中工作（我认为这不会正常工作 a）如果我将 VS2013 用于同一个项目；b) 如果我尝试使用 Razor 3 功能)：
Change the web.config to use old webpagesversion:
更改 web.config 以使用旧webpages版本：
<add key="webpages:Version" value="2.0.0.0" />
To make sure that this does not impact the production in any way I added a web.config transformation:
为了确保这不会以任何方式影响生产，我添加了一个 web.config 转换：
<add key="webpages:Version" value="3.0.0.0" xdt:Transform="SetAttributes" xdt:Locator="Match(key)" />
Unfortunately this workaround has issues (that I have noticed so far):
不幸的是，这个解决方法有问题（我到目前为止已经注意到了）：
- Extension methods (like
Html.RenderPartial()are not recognized and show up as error in the designer).
- 扩展方法（例如
Html.RenderPartial()无法识别并在设计器中显示为错误）。

I got this answer from Microsoft developer:
我从微软开发人员那里得到了这个答案：
MVC 5/Razor 3 tooling support for VS 2012 has not shipped yet. We hope to ship this support in Mid November.
对 VS 2012 的 MVC 5/Razor 3 工具支持尚未发布。我们希望在 11 月中旬提供此支持。
So the accepted answer is true for now but we can plan to soon have this support in VS2012 as well.
所以目前公认的答案是正确的，但我们可以计划很快在 VS2012 中也提供这种支持。

For me, my issue was that I had my build files being output to a directory other than bin. Once my files we're output to bin, then my syntax highlighting came back.
对我来说，我的问题是我的构建文件被输出到bin. 一旦我的文件输出到bin，我的语法高亮就回来了。
One way to fix this is to create a post-build action which copies the files in the project-rooted bin folder (vs a filter outside of the project) to your target directory.
解决此问题的一种方法是创建一个构建后操作，将项目根目录中的 bin 文件夹（与项目外部的过滤器）中的文件复制到您的目标目录。
