- 后来我又拖了一个.NET2.0的应用程序,直接提示找不到对应的.NET版本.
請在XP SP3上安裝 .NET Framework 3.5. (.NET Framework 3.5 includes .NET Framework 2.0 SP1 and 3.0 SP1)
- NET 4.0是不是不兼容其他的版本?
The .NET Framework has two main components: the common language runtime (CLR) and the .NET Framework class library. The common language runtime is the foundation of the .NET Framework.
.NET Framework 3.5 uses CLR version 2.0 and so does .NET Framework 2.0 or 3.0, while .NET framework 4.0 uses v4.0.
.NET Framework 3.5 includes .NET Framework 2.0 SP1 and 3.0 SP1 as prerequisite.
Please read the following blog to understand the relationship between .NET 2.0, 3.0 and 3.5.
See: http://www.danielmoth.com/Blog/2007/06/net-framework-35.html
Windows 7 (all editions) includes the .NET Framework 3.5 with SP1 as an OS component.
This means you have the .NET Framework 2.0 as OS component if you have installed Windows 7.- XP 下运行.NET4.0应用程序需要特殊的配置吗?
XP SP3 已安裝 .NET Framework 4. WPF应用程序无法运行,也不报错. 會不會是這個問題?

关於你在xp sp3上运行.NET2.0的应用程序的问题, 请安装 .NET Framework 3.5, 因為3.5內含2.0 SP1 和 3.0 SP1.
至於xp sp3上已装 .NET 4.0, 请你参考 http://bbs.ruanmei.com/thread-276475-1-1.html 用 netfx_setupverifier.exe 检测.net framework安装状态
