Visual Studio 2010对.NET 4.5的支持
[英]Visual Studio 2010's support for .NET 4.5
问题描述
Having read numerous posts on the net and here at Stack Overflow about this I still am unsure as to whether VS 2010 supports .NET 4.5. 
在网上阅读了很多帖子，在Stack Overflow上有关于此问题，我仍然不确定VS 2010是否支持.NET 4.5。 MS states on http://www.microsoft.com/en-in/download/details.aspx?id=30653 that it is an in place upgrade .NET 4. MS在http://www.microsoft.com/en-in/download/details.aspx?id=30653上声明它是一个升级版.NET 4。
Does this mean that once .NET 4.5 has been installed on a machine with VS2010 installed I can still leave my target as .NET 4 but it will actually be using 4.5? 这是否意味着一旦安装了VS2010的机器上安装了.NET 4.5，我仍然可以将我的目标保留为.NET 4，但实际上它将使用4.5？ For various reasons I cannot upgrade to VS 2012. 由于各种原因，我无法升级到VS 2012。
All pointers greatly appreciated. 所有指针都非常感谢。

.NET 4.5 does not install side by side with .NET 4.0, it replaces it. .NET 4.5不与.NET 4.0并排安装，而是替换它。 But it still allows you to target .NET 4.0 with it installed, so it shouldn't break the installation AFAIK. 但它仍然允许您安装.NET 4.0，因此它不应该破坏安装AFAIK。 But you can't utilize any of the .NET 4.5 features since you can't target anything higher than .NET 4.0 in Visual Studio 2010. 但是您无法使用任何.NET 4.5功能，因为您无法在Visual Studio 2010中定位高于.NET 4.0的任何内容。
If you need to use these features, you will have to install Visual Studio 2012. 如果需要使用这些功能，则必须安装Visual Studio 2012。
