Simple CQRS example
I'm wondering how to implement business rule depends on entity current state. For example: "You can change the name of the InventoryItem only if new name is longer".
It loos like the `AggregateRoot` `Version` field is never updated. It should probably be updated at the end of the `LoadsFromHistory` method (which should probably be renamed `LoadFromHistory`), with the...

We keep getting this questions from people who use message buses to build read models, it is the FAQ question, but it is still here https://github.com/gregoryyoung/m-r/blob/master/CQRSGui/Global.asax.cs#L45 Be May it is...
Even though I know this should be seen as a demonstration for learning CQRS and is just the most simplest implementation... I have seen people jump onto this horse and...
In case anyone's wondering, there are races between event handlers and the read model facade after commands are issued. This is due to the use of `ThreadPool.QueueUserWorkItem` in `FakeBus.Publish`. You...
