 `UserFriendlyException` is a special type of exception. You can directly show a error message dialog to the user by throwing such an exception.
 
+> For Blazor Server, exceptions must be handled manually. Otherwise it crashes the whole application. Auto Exception Handling is not possible with Blazor Server right now, please follow [this issue](https://github.com/abpframework/abp/issues/8195) to see progress. In meantime, you can use try-catch blocks and call the `HandleErrorAsync` method of ABP to handle errors manually, which shows an error dialog for you.
