I want to convert my project (it uses .NET 4.0) to .NET 3.5. How can I do this in Visual Studio 2010 ?!

推荐答案

进入项目属性（右键单击项目，然后单击属性），在应用程序下部分，并将目标框架更改为.NET Framework 3.5或.NET Framework 3.5 Client Profile，然后修复出现的任何错误（如果有）。

Go into your project properties (right click your project, and click "Properties"), under the "Application" section, and change "Target framework" to ".NET Framework 3.5" or ".NET Framework 3.5 Client Profile", then fix any errors that appear (if any).
