# MVC1002: Route attribute cannot be applied to page handler methods

|
|
| **Rule ID** |MVC1002|
|
|
| **Fix is breaking or non-breaking** |Non-breaking|
|
|
|
|
## Cause
|
|
|
|
An attribute implementing <xref:Microsoft.AspNetCore.Mvc.Routing.IRouteTemplateProvider> was applied to a Razor Page handler method.
|
|
|
|
### Rule description
|
|
|
|
Razor Page handler methods are selected after routing is completed, and consequently cannot contribute a route. Applying a route attribute such as `HttpGet` or `HttpPost` to a Razor Page handler is not supported.
|
|
|
|
```csharp
|
|
public class IndexModel : PageModel
|
|
{
|
|
[HttpGet("/my-url")]
|
|
public IActionResult OnGet() => Page();
|
|
}
|
|
```
|
|
|
|
## How to fix violations
|
|
|
|
Remove the route attribute from the handler. Routes can be specified for a Razor Page using an `@page` directive or by using conventions. For more information, see [custom routes in Razor Pages](<xref:razor-pages/index#custom-routes>).

|
## When to suppress warnings
|
|
|
|
Don't suppress warnings from this rule.
