我正在使用Visual Studio 2005.爲什麼不支持此行?在VS2005中使用Linq會導致錯誤
using System.Linq;
錯誤:之前,不支持的.NET Framework V3.5
Error 1 Validation (XHTML 1.0 Transitional): Attribute values must be enclosed in quotation marks.
Error 2 The type or namespace name 'Linq' does not exist in the namespace 'System' (are you missing an assembly reference?)
