You need to set the AppHost
config to debug
mode:
SetConfig(new EndpointHostConfig {
DebugMode = true,
});
For performance reasons changes are only monitored for in Debug mode. See here for more information.
Automatic reload of modified views, layout templates and partials (in Debug mode)
The best way to avoid the Start-Up penalty is to avoid having to restart the AppDomain in the first place. So in Debug Mode we'll also do this where a background file system watcher monitors all pages, partials and Layout templates for modifications and recompiles and auto-reloads them on the fly, all-ready to deliever instant response time once the page is requested.
