国内很多网站空间都只支持.NET 2.0 和 .NET 3.0 3.5，很少有空间商支持.NET 4的，即使有个别支持.NET 4，但是不支持MVC的默认路由访问形式。
Go Daddy 的主机支持，并且费用很低，系统为 Win 2008 R2 64位，10GB网站空间，网站并发最便宜的也支持100个，PHP支持5.2和5.3，.NET支持 ASP.NET v1.0/2.0/3.0/3.5 和 ASP.NET v4.0，默认为.NET 4，并且默认已经支持MVC 2，如果要支持MVC3，只需要在发布站点的时候，多复制几个DLL文件到BIN文件夹就可以了，DLL清单如下：
System.Web.Abstractions.dll
System.Web.Helpers.dll
System.Web.Mvc.dll
System.Web.Razor.dll
System.Web.Routing.dll
System.Web.WebPages.dll
System.Web.WebPages.Razor.dll
System.Web.WebPages.Deployment.dll
否则会报如下：
页面显示错误
