Code Completion (IntelliSense)
To get you familiar with JetBrains Rider's code completion features, here are some implementation basics:
The suggestion list of Automatic Completion appears as soon as you start typing a new identifier. The suggestion list of Basic Completion appears when you press Ctrl+Space.
Two other completion commands, Smart Completion Ctrl+Alt+Space and Class Name Completion Shift+Alt+Space apply advanced algorithms to add more items to the suggestion list.
By default, all JetBrains Rider's completion features support CamelHumps, that is you can type the initial letters of a compound name parts and the name will appear in the list of suggestions.
When you use code completion over existing code items, you can either insert the selected completion suggestion by pressing Enter or substitute the existing identifier with the selected suggestion by pressing Tab. You can configure this behavior with the Insert selected suggestion by pressing enter, dot, or other context-dependent keys and Enter inserts suggestion even if completion popup is not focused checkboxes on the Editor | General | Code Completion settings page.

You may want some symbols not to be suggested, for example, if you have something similar to a system type in your solution, say
MyFramework.MyCollections.List, but you are not actually using it. To exclude such symbols from the suggestions, add them to the Exclude from import and completion list on the page of JetBrains Rider settings Ctrl+Alt+S. The format of the entries isFully.Qualified.Name,Fully.Qualified.Name.Prefix*, or*Fully.Qualified.Name.Suffix. Generic types are specified asList`1. -
When you select items in completion lists using keyboard, the selection will jump to the first item after the last item and vice versa. You can disable this behavior by clearing Cyclic scrolling in list on the page of JetBrains Rider settings Ctrl+Alt+S.
