在Visual Studio .NET 2012 4.5.1 preVIEW支持 [英] .NET 4.5.1 Preview Support in Visual Studio 2012

问题描述

首先让我补充一些背景错误我得到的，我已经安装了.NET 4.5.1 preVIEW和第一件事，我注意到，在VS 2012是.NET 4.5.1没有可用的框架列出。我不知道这是否是正确的行为，因为这仅仅是一个升级到4.5，所以我猜VS 2012应该列出它。

First let me add some context to error I get, I have installed .NET 4.5.1 Preview and first thing that I noticed in VS 2012 is that .NET 4.5.1 isn't listed in available frameworks. I'm not sure if this is correct behavior because this is just an upgrade to 4.5 so I guess VS 2012 should list it.

更进一步，当我安装了VS 2013 preVIEW，升级我的项目.NET 4.5.1，打开了解决方案在VS 2012新的.NET版本又出现了，所以我不知道这是一个错误，在VS 2012年或不是？好了，所以现在我有.NET 4.5.1在VS 2012，当我尝试建立一个项目，我会收到以下错误

Further more when I installed a VS 2013 Preview, upgraded my project to .NET 4.5.1 and opened the solution in VS 2012 new .NET version reappeared so I'm not sure if this is a bug in VS 2012 or not ? Ok so now I have .NET 4.5.1 in VS 2012 and when I try to build a project I get the following error

Error   3   The task factory "CodeTaskFactory" could not be loaded from the assembly "C:\Program Files (x86)\MSBuild\12.0\bin\Microsoft.Build.Tasks.v4.0.dll". Could not load file or assembly 'file:///C:\Program Files (x86)\MSBuild\12.0\bin\Microsoft.Build.Tasks.v4.0.dll' or one of its dependencies. The system cannot find the file specified.  D:\Projects\MyProject\Master\Source\.nuget\nuget.targets    71  9   MyProject.Core.Modules

NuGet.targets报告行

NuGet.targets reported line

<SetEnvironmentVariable EnvKey="VisualStudioVersion"
EnvValue="$(VisualStudioVersion)" Condition=" '$(VisualStudioVersion)'
!= '' AND '$(OS)' == 'Windows_NT' " />

在我看来，由于某种原因VS 2012无法解析路径或组件，所以我不知道我是否应该修正一些东西在NuGet.targets或者是一个Visual Studio的事情，任何想法？

It seems to me that for some reason VS 2012 can't resolve the paths or assemblies so I'm not sure if I should fix something in the NuGet.targets or is it a Visual Studio thing, any ideas ?

感谢
