我从http://www.microsoft.com/en-in/download/details.aspx?id=30653

安装的4.5框架后，我重新启动机器。在VS 2010中是否有新的项目，默认情况下4.0框架在目标框架被指定为.NET Framework 4.0中的项目属性应用程序 - >分配创建。但我想改变到4.5框架。但是4.5的框架没有列出。

After installing the 4.5 framework I restarted the machine. In vs 2010 if any new project is created by default 4.0 framework is assigned in project properties Application->Target framework is assigned as .NET Framework 4.0. But I want to change to 4.5 framework. But 4.5 framework is not listed.

我的问题是，我应该做一些设置更改列出VS2010 4.5框架或VS2010使用.NET 4.5，我不能下发展的任何应用程序？

My question is , should i do some settings changes to list 4.5 framework in vs2010 or i can't develope any app using .net 4.5 in vs2010?

谢谢 萨兰

推荐答案

没有，你不能用VS2010面向.NET 4.5，你不能面向.NET 4.0与VS2008以同样的方式。您将需要安装VS2012如果你想针对.NET 4.5。

No, you can't target .NET 4.5 with VS2010 the same way you couldn't target .NET 4.0 with VS2008. You will need to install VS2012 if you want to target .NET 4.5.
