Answer 1

Or If you added the any framework / Extensions into your solution. You may right click the reference folder in the Solution Explorer then click "Send Reference to F# Interactive"

Answer 2

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.
