Answer 1

You don't need to "add" .NET 3.5 to VS2010. When you create a new project, you just specify which version of .NET you want to target. (You can change this later, too, in project properties.)

Answer 2

Try this link: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=ab99342f-5d1a-413d-8319-81da479ab0d7&displaylang=en

It is the download package for .NET 3.5. Maybe you don't have 3.5 installed.

EDIT: Updated link to point to .NET 3.5 SP 1 instead as Hans points out.

Answer 3

好的，现在我了解了在Visual Studio 2008上安装时发生的情况。显然，默认情况下未安装3.5框架（至少在我工作的地方，默认情况下他们不会默认安装它。VS2010不会为您安装3.5-使用Windows Server Manager安装它，然后安装3.5，您将立即能够在VS中重新定位项目。

Answer 4

.NET FRAMEWORK 4 contains all precedents versions. Just target your project in properties of your application in VS2010
