Hot Reload settings

General settings


Enable Hot Reload when debugging (excluding Mono)	When this option is on, you can edit your code and continue debugging without restarting. There are cases when modifying the code is not possible and a restart is required. These include changing signatures, modifying generic functions, renamings of any kind, and some more. If this happens JetBrains Rider will make you aware by showing a tooltip. note Debugging with Hot Reload requires .NET 8 as the target framework.
Automatically apply changes on step and resume	If this option is off, your changes will not be synchronized with the debugger when you step or resume the process, instead, you will need to apply your changes explicitly: click Apply changes on the editor banner that appears or choose Apply changes from the `AltEnter` popup. This approach is similar to the Hot Swap in Java debuggers. It lets you continue debugging regardless of your changes, and it works well when your changes do not affect the code you are currently stepping over. If this option is on, all changes that you made when the process is paused in the debug session will be applied automatically as soon as you use one of the stepping commands or resume the process `F5`, but you will always be notified of the changes and be able to apply them explicitly: Note that the changes will be sent to the process before the debugger makes the next step or resumes the program. Therefore, the debugging session could be broken, for example if your changes lead to a build failure. This approach is similar to Visual Studio debugger. Although your changes can break the debugging session, it makes sure that the code in the editor is synchronized with the debugger at each step.
Enable Hot Reload when running without debugging (.NET 6.0 and later)	This option enables Hot Reload when you run code without debugging `CtrlF5`. If it is disabled, you can make any edits, but they will not be synced with the running application. note When running, Hot Reload works cross-platform with projects targeting .NET 6.0 or later.
