blocks|key|162170|text|我发现修复IntelliSense问题的最好方法是简单地在解决方案资源管理器中卸载该项目，然后重新加载该项目。在那之后，IntelliSense总是为我工作，我不会丢失书签、断点或任何其他设置。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|162171|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I found that the best way to fix IntelliSense issues is to simply unload the project in the solution explorer and load the project again. After that IntelliSense is always working for me and I do not loose bookmarks, breakpoints or any other settings.

I use VS 2013 and I had the same problem.
My solution was update VS to last version. I my case Update 4.
Simply reference in project must match with assembly in GAC on computer (OS). Intellisense come from VS not from project.

I am facing a weird problem in my Visual Studio 2013 ASP.NET MVC 5 project. All of a sudden, the IntelliSense in the Controller classes of the MVC 5 project are not working at all.

I have other class library projects in my solution and IntelliSense is working in those class library project files, but the problem is only within the MVC project. Usually these kinds of problems are solved by restarting Visual Studio: not only did I restart Visual Studio, but I also restarted my computer, and the IntelliSense problem is not getting fixed at all.

Are there any other steps that can get me IntelliSense back?
