## Remarks

This method is intended for use with [ResourceNotificationService.PublishUpdateAsync(IResource, string, Func<CustomResourceSnapshot, CustomResourceSnapshot>)](/reference/api/csharp/aspire.hosting/resourcenotificationservice/methods.md#publishupdateasync-iresource-string-func-customresourcesnapshot-customresourcesnapshot) and [ResourceNotificationService.PublishUpdateAsync(IResource, string, Func<CustomResourceSnapshot, CustomResourceSnapshot>)](/reference/api/csharp/aspire.hosting/resourcenotificationservice/methods.md#publishupdateasync-iresource-string-func-customresourcesnapshot-customresourcesnapshot). Updating health reports also recomputes [CustomResourceSnapshot.HealthStatus](/reference/api/csharp/aspire.hosting/customresourcesnapshot/properties.md#healthstatus) based on the snapshot state.
