}
得到以下错误:-
"System.Web.Http.HttpConfiguration"不包含"EnableQuerySupport"的定义,也没有扩展方法"EnableQuerySupport" 接受类型为"System.Web.Http.HttpConfiguration"的第一个参数 可以找到(您是否缺少使用指令或程序集 参考?
在Visual Studio中,转到"Tools",然后转到"Nuget Package Manager",然后转到"Package Manager Console"
运行以下命令,它将解决问题。已经测试过了。
update-package microsoft.aspnet.webapi -reinstall
