use
await detachedContext.Set<Entity>().DeleteAsync(new KeyValue(1), new KeyValue(2));

Hello Leonardo,

I'm trying to use the DeteleAsync feature with the new syntax, like follows:

await detachedContext .Set<Entity>() .DeleteAsync(someEnumerable.Select(e=>e.Id).ToArray()); - this returns the IComparable error.
await detachedContext .Set<Entity>() .DeleteAsync(someEnumerable.Select(e=> new KeyValue(e.Id)).ToArray(); - this returns IndexOutOfRange exception.

I think I'm doing something wrong, but based on the parameter metadata that is showing up in the Intellisense, I can only figure out the above examples.
Can you write down an example of usage where the Entity is an actual complex object ?
Thank you!
