推荐答案

F#交互式窗口不了解您的项目引用，因此您需要使用 #r 指令显式注册它们.例如，尝试在F#Interactive中键入 #r"MySql.Data" 或 #r @"C:\ ... \ MySql.Data.dll" 使用 MySql 命名空间中的任何类型.

The F# interactive window is unaware of your project references, so you need to explicitly register them using the #r directive. For example, try typing #r "MySql.Data" or #r @"C:\...\MySql.Data.dll" into F# interactive before attempting to use any of the types in the MySql namespace.
