|
> A **catch-all** parameter may match routes incorrectly due to a [bug](https://github.com/dotnet/aspnetcore/issues/18677) in routing. Apps impacted by this bug have the following characteristics:
|
||
|
|
>
|
||
|
|
> * A catch-all route, for example, `{**slug}"`
|
||
|
|
> * The catch-all route fails to match requests it should match.
|
||
|
|
> * Removing other routes makes catch-all route start working.
|

> See GitHub bugs [18677](https://github.com/dotnet/aspnetcore/issues/18677) and [16579](https://github.com/dotnet/aspnetcore/issues/16579) for example cases that hit this bug.

|
||
|
|
> AppContext.SetSwitch("Microsoft.AspNetCore.Routing.UseCorrectCatchAllBehavior", true);
