Code Completion features help you write code faster by providing a set of items to complete based on surrounding context. For more information, refer to Code completion (IntelliSense).
Currently, only Basic code completion is supported in F#. It suggests namespaces, types, methods, fields, properties, and so on as you type.
You can see the entire list of suggestions by placing the caret at the position where you're going to type your code (or on an existing member) and press Control+Space.
