MVC Razor视图Intellisense在VS 2013/2015/2017中打破(MVC Razor view Intellisense broken in VS 2013/2015/2017)

我在VS2010中编写了一个现有的项目，当它在VS2010中加载完美时。

当我在VS2013中加载相同的项目时，MVC Razor视图包含很多错误，就像在views文件夹中缺少配置文件一样。

似乎没有使用从根和视图文件夹的配置文件正确加载剃刀编辑，而是给我错误，如...

The name 'model' does not exist in the current context

和...

'System.Web.WebPages.Html.HtmlHelper' does not contain a definition for 'LabelFor' and no extension method 'LabelFor' accepting a first argument of type 'System.Web.WebPages.Html.HtmlHelper' could be found (are you missing a using directive or an assembly reference?)

...

有什么想法会造成这个吗？

编辑：根据请求配置文件....

从主web.config文件（不是所有的，因为它的方式太大，不能发布）

“〜/ Views /”中的配置文件...

I have an existing project written in VS2010 which when loaded in VS2010 works perfectly.

When I load this same project in VS2013 the MVC Razor views contain lots of errors as if the config file is missing from the views folder.

It appears to have not loaded the Razor editor correctly using the config files from both the root and the views folder and instead gives me errors like ...

The name 'model' does not exist in the current context

and ...

'System.Web.WebPages.Html.HtmlHelper' does not contain a definition for 'LabelFor' and no extension method 'LabelFor' accepting a first argument of type 'System.Web.WebPages.Html.HtmlHelper' could be found (are you missing a using directive or an assembly reference?)

...

Any idea what would cause this?

Edit: Config files as requested ....

From main web.config file (not all of it as it's way too big to post)

Config file in "~/Views/" ...

最满意答案

我认为编辑@ ChrisMoschini的帖子，但认为这是不同的。我的问题是我启动了一个新的MVC5应用程序，并盲目复制了一个旧的MVC3项目的web.config设置，我想用作一个模板/起点。这样做使我在web.config中引用了一些无效的版本。

要修复，我创建了另一个新的MVC5项目，并确保我的坏项目中的以下配置值匹配香草，未修改的MVC5应用程序。 再次，不要盲目复制这些版本号。 只要确保它们匹配您想要上班的版本的香草MVC应用程序

在root web.config ：

在Views\Web.config ：

I considered editing @ChrisMoschini's post, but thought it was different enough. My issue was that I started a new MVC5 application, and blindly copied over too many web.config settings from an old MVC3 project I wanted to use as a template/starting point. Doing this caused me to have some invalid versions referenced in my web.config.

To fix, I created another new MVC5 project and made sure the following config values in my bad project matched the vanilla, unmodified MVC5 app. Again, do not blindly copy these version numbers. Just make sure they match a vanilla MVC app of the version that you're trying to get to work

in root web.config:

in the Views\Web.config:
