 Not all of the ASP.NET Core Options features are supported in Razor components. For example, <xref:Microsoft.Extensions.Options.IOptionsSnapshot%601> and <xref:Microsoft.Extensions.Options.IOptionsMonitor%601> configuration is supported, but recomputing option values for these interfaces isn't supported outside of reloading the app by either requesting the app in a new browser tab or selecting the browser's reload button. Merely calling [`StateHasChanged`](xref:blazor/components/lifecycle#state-changes-statehaschanged) doesn't update snapshot or monitored option values when the underlying configuration changes.
