Question

我使用带有JSON的.NET 4.0创建了一个网站。我现在正试图在远程主机服务器（网络解决方案）上托管该站点，当我打开网站时出现以下错误：

web.config文件中无法识别的配置部分system.web.extensions。

我打电话给他们支持他们说他们只能托管.NET 3.5网站而不是.NET 4.0（他们的服务器上没有.NET 4.0框架）。

是否有解决方法使其在.NET 3.5框架中运行？

这是我的配置文件：

Answer 1

是的，您应该检查iis应用程序池并确保它正在运行.net 4.0。（右键单击iis中的站点并查看属性，您应该能够更改它在那里使用的框架。）

并确保稍后在命令提示符下运行“iisreset”命令。
