There is no such built-in support.

Obviously if your IEnumerable also implements IOrderedEnumerable then you don't need to do an additional check, otherwise you'd have to implement an extension method like you did.

You might want to add a direction parameter or change its name to IsSortedAscending, by the way. Also, there might be different properties in your T to sort on, so it would have to be obvious to you in some way what "sorted" means.
