Ctrl+Shift+Space
Whenever you are writing or studying a function call, JetBrains Rider helps you view details on the allowed arguments for all overloads of the function. In a popup, you will see all public signatures with parameters and brief description taken from the function's XML documentation, if it is available .
tip
You can also display parameter names inline in method calls with parameter name hints, or you can get more details of the function with quick documentation ( Ctrl+K, I).
Use Parameter Info
As you are typing parameters, JetBrains Rider automatically highlights the next signature compatible with the entered parameters, and grays out inapplicable signatures. To study alternative signatures of an existing function call, set the caret inside the function's parentheses and then press Ctrl+Shift+Space or choose View | Parameter Info from the main menu.
When the parameter information popup is shown, you can press Ctrl+Shift+Space to scroll through the list of method overloads.
The parameter information popup is displayed as long as you type or move the caret within the method parentheses; you can close it by pressing Escape.
Configure Parameter Info
By default, the parameter information popup appears as soon as you type the opening parenthesis of a function call. If necessary, you can disable the automatic appearance or display the popup after a timeout using the Show the parameter info popup in preference on the Editor | General | Code Completion page of JetBrains Rider settings Ctrl+Alt+S. If the automatic appearance is disabled, you can always show the parameter information popup by pressing Ctrl+Shift+Space while your caret is inside the function's parentheses.
