找不到类型或名称空间名称“ Moq”（是否缺少using指令或程序集引用？）

Question

我确实使用程序包管理器控制台安装了Moq（Install-Package Moq -version 4.1.1309.1617 -projectname EssentialTools.Tests）

我的目标是.NET FRAMEWORK 4.5，（我确实尝试将其更改为4 Client Profile），仍然出现错误。我在“使用最小起订量”下收到错误消息。任何帮助，将不胜感激。谢谢

       new Product {Name = "Lifejacket", Category = "Watersports", Price = 48.95M},
       new Product {Name = "Soccer ball", Category = "Soccer", Price = 19.50M},
       new Product {Name = "Corner flag", Category = "Soccer", Price = 34.95M}

右键单击引用并从已安装的包文件夹中添加 Moq。希望能帮助到你！
