I was working on an ASP.NET MVC 4 in VS2013 and everything was fine, then I've uninstalled 2013 and installed 2015, I was able to open the project, build it and even run, everything works fine (run/debug). The problem is that all my views are covered in errors:

the name 'model\Scripts\Url...' does not exist in the current context  

在另外，在模型列表的。凡方法示出了一个错误，以及所有的@Html帮手。我想强调的是，该项目仍然工件W \\ o任何问题，所以这个问题是相关的UI或包装。我试图强制卸载\\升级Microsoft.AspNet.MVC但包管理器控制台将引发错误并回滚尝试。我可以提供任何必要的信息，如果有帮助，谢谢你在前进。

In addition, the .Where method of a list in the model shows an error as well as all the @Html helpers. I want to emphasize that the project still works w\o any problems so the issue is UI or package related. I tried to force uninstall\upgrade Microsoft.AspNet.MVC but the package manager console throws an error and rolls back the attempt. I can provide any necessary info if it helps, thank you in advance.

推荐答案

新推出的VS2015 IDE似乎不再支持MVC3 / MVC4项目，同时它仅支持MVC5：

The newly released VS2015 IDE seems to no longer support MVC3/MVC4 projects, while it only supports the MVC5:

如果有严格的要求将任何现有MVC3 / 4的解决MVC5（对于2015年VS），你可以在列出的步骤进行

If there are strict requirements to convert any existing MVC3/4 solution to MVC5 (for VS 2015), you can proceed with the steps listed in the How to Upgrade an ASP.NET MVC 4 and Web API Project to ASP.NET MVC 5 and Web API 2 guide.

似乎安装 VS 2015 SP2 更新，它的表现要好得多。如果你有机会的话，我建议你升级你的IDE和检查问题是否会消失。

It seems that after installing the VS 2015 SP2 update, it behaves much better. If you have a chance, I suggest that you upgrade your IDE and check if the issue goes away.
