This document summarizes the new features in NServiceBus 3.0, including improved out-of-the-box experience, naming conventions, handling timeouts, bridging remote sites, and other random features. Key points include default storage bundled with NServiceBus, conventions based on endpoint names, a new timeout manager for managing timeouts at each endpoint, and using gateways to bridge communication between physical sites. The document concludes with a Q&A section.

2. Main goal for 3.0
Better out of the box experience

3. Game plan
• Storage
• Naming endpoints
• Handling time
• Bridging remote sites
• Random stuff
• Q&A

4. What is a bus anyway?

5. We need to store stuff

6. Storage needs
Sagas
Subscriptions
App Timeouts App
Bus.dll Bus.dll
Available workers
Deduplication
Scaling out

7. • Default storage
• Bundled with NServiceBus
• NH=>NServiceBus.NHibernate.dll

8. It’s all in the name

9. Conventions based on the
endpoint name
Database Orders
Input queue Orders
Orders
Timeouts Orders.Timeouts
Bus.dll
Gateway url http://localhost/orders

10. Naming endpoints
• Defaults to your namespace
• Attribute: [EndpointName(“Orders”)]
• Install: /serviceName:Orders
• Configure.DefineEndpointName(…)

11. Demo
Storing sagas in RavenDB

12. Durable timeouts vNext

13. 3.0 Timeout manager
Business Timeout
Timeouts
Logic Manager

14. Bending time to your will
• Sagas
– RequestUtcTimeout<T>(…)
– IHandleTimeout<T>
– v2.6 Timeouts still supported
• Bus.Defer<T>(…)
• All endpoints have a local
timeoutmanager

15. Demo
Using timeouts

16. Bridging remote sites

17. Gateway

18. What can the gateway do
for you?
• Bridge physical sites
• Supports multiple channels
• Does de-duplication
• Performs retries
• Can act as a alternate channel for
administrative messages
• Enable Browser  NServiceBus

22. Other features
• Unobtrusive mode
