所有系统缺少引用的Visual Studio 2013的NuGet异步 [英] All system references missing Visual Studio 2013 NuGet Async

问题描述

我有一个解决方案/团队项目建立在Visual Studio 2013年有一段时间有安装了NET Framework 4.0中工作的NuGet Microsoft.Bcl异步包。今日开盘项目的所有默认的.NET系统库的引用无法找到的时候，他们只是旁边有一个警告符号。我有49个警告建设项目中所有说'引用的组件System.X无法找到时。或引用的组件Micr​​osoft.X'找不到。然而，在溶液中引用其他项目保持不变。

I have a solution/team project set up in visual studio 2013 and for some time have had a working NuGet Microsoft.Bcl Async Package installed for NET Framework 4.0. Today when opening the project all of the default .NET system library references cannot be found, They just have a warning symbol next to them. I have 49 warnings when building the project all saying 'The referenced component 'System.X' could not be found. Or 'The referenced component 'Microsoft.X' could not be found. Yet references to other projects in the solution remain intact.

如果这是我一直在使用内置的版本控制系统，以保持我的code备份和从我的其他电脑具有相同配置的访问任何意义。

If it is of any significance I have been using the built in version control system to keep backups of my code and access it from my other pc with the same configuration.

综观其他问题上的计算器类似问题的人似乎朝的NuGet指向作为可能导致这个问题，但没有，这似乎为我工作的任何解决方案。我曾尝试删除并重新添加引用同时使用文件浏览器和框架标签明显的解决方案，但既不是迄今工作。

Looking at the other questions on stackoverflow with similar issues people seem to point towards NuGet as potentially causing the problem but without any solution that seems to work for me. I have tried the obvious solution of removing and re-adding the reference using both the file browser and the Framework tab but neither has worked so far.

我目前不能编译项目，因为我得到这样的警告，无疑被摆在首位的丢失的引用造成的。

I cannot currently compile the project as I get this warning, undoubtedly caused by the missing references in the first place.

推荐答案

我能够首先运行在解决方案中所有的Nu​​Get包更新，然后再取出，以解决这个问题，并重新添加引用库包含或重写封装

I was able to solve this issue by first running an update on all NuGet packages in the solution and then removing and re adding references to the libraries included or overridden by the package.
