Releasing NServiceBus.Azure 5.0.0

Hi all,

I have published a new release of the Windows Azure support earlier today. This release is labeled 5.0.0 as it includes a few breaking changes, related to decoupling our binaries from the windows azure binaries that are distributed through VS (and not through nuget)

The first and probably most breaking change is the removal of the dependency to ServiceRuntime.dll, we will now lookup your version of the serviceruntime at runtime instead of at compile time. But because we had an inheritance dependency on one of it’s types in the past (through our RoleEnvironment class in NServiceBus.Hosting.Azure), we had to change the way this dependency works. So now we do composition over inheritance for the roleentrypoint as shown in the samples https://github.com/Particular/NServiceBus.Azure.Samples/blob/5.0.0/VideoStore.AzureServiceBus.Cloud/VideoStore.Sales/WorkerRole.cs

The second breaking change is that we removed our dependency on the WindowsAzure.Diagnostics.dll as well (as this is also distributed by the VS tooling). This forced us to remove the AzureDiagnostics configuration method, which configured diagnostics for you in the past. But as VS now also comes with a nice editing environment for the diagnostics settings, this functionality was not that usefull anymore so we removed it. Instead you should now configure diagnostics in VS itself and use .TraceLogger() instead.

The upside of both changes is that NServiceBus will now work irrespective of the Visual Studio tools your using (Either VS2012, VS2013, SDK 2.1, SDK 2.2 and future versions), so for a large part I hope we got rid of dll hell (Except for windows azure storage client, but that is another story)

Additionally, we also splitted the nuget packages for supporting azure services as transports and as persisters. Now there are 2 more packages that contain the transports

NServiceBus.Azure.Transports.WindowsAzureStorageQueues (Storage SDK 2.1.0.0)
NServiceBus.Azure.Transports.WindowsAzureServiceBus (ASB 2.2.0.0)

Which can be used indepently from the persisters, which are still in

NServiceBus.Azure (Storage SDK 2.1.0.0)

This change will make it a lot easier for hybrid scenarios where people only want to use windows azure servicebus for example with the regular on premises nservicebus.host.exe

I hope the upgrade will go smoothly for you, most changes should be in the azure cloudservice roleentrypoint, people using the transports on premises should not be impacted to much, besides a change in assembly and package references.

I have gone through the upgrade of the sample projects already, so when in doubt you can refer to https://github.com/particular/nservicebus.azure.samples/tree/5.0.0 for an example.

If you have further questions, do not hesitate to contact me.

MessageHandler – Early adopter program

Those of you who have been following me lately, know I’ve been working on a ‘Message processing as a service’ offering called MessageHandler and as MessageHandler is taking shape quickly, we decided to open it up for a few more early adopters.

As part of the Early Adopter Program, you’ll play a pivotal role in the validation of our service and it’s technology components. You’ll have access to the latest bits far before everyone else, giving you a strategic advantage over your competition. Furthermore you will also have the opportunity to provide suggestions to improve or even extend the capabilities before they’re released to the general public, giving you a say in how the final solution turns out.

So hurry up and subscribe for the early adopter program, seats are limited! You can sign up on http://www.messagehandler.net
