# MVC1001: Filters cannot be applied to page handler methods
| | Value |

| **Rule ID** |MVC1001|
| **Fix is breaking or non-breaking** |Non-breaking|
## Cause
An attribute implementing <xref:Microsoft.AspNetCore.Mvc.Filters.IFilterMetadata> was applied to a Razor Page handler method.
### Rule description
Razor Page handler methods are selected after MVC filter exeuction has started, and consequently cannot contribute filters to execute. Applying a filter to a Razor Page handler is unsupported and always incorrect.
Remove the filter from the handler and apply it to the page model. If a filter has to be applied to a specific handler, consider using multiple Razor Pages.
