Need some help/advice on WCF Per-Call Service and NServiceBus interop.
- by Alexey
I have WCF Per-Call service wich provides data for clients and at the same time is integrated with NServiceBus.
All statefull objects are stored in UnityContainer wich is integrated into custom service host.
NServiceBus is configured in service host and uses same container as service instances.
Every client has its own instance context(described by Juval Lowy in his book in chapter about Durable Services).
If i need to send request over bus I just use some kind of dispatcher and wait response using Thread.Sleep().Since services are per-call this is ok afaik.
But I am confused a bit about messages from bus, that service must handle and provide them to clients. For some data like stock quotes I just update some kind of statefull object and and then, when clients invoke GetQuotesData() just provide data from this object.
But there are numerous service messages like new quote added and etc.
At this moment I have an idea to implement something like "Postman daemon" =)) and store this type of messages in instance context. Then client will invoke "GetMail()",recieve those messages and parse them. Problem is that NServiceBus messages are "Interface based" and I cant pass them over WCF, so I need to convert them to types derieved from some abstract class.
Dunno what is best way to handle this situation.
Will be very gratefull for any advice on this.
Thanks in advance.
