Just started upgrading an existing v2 solution to v3 using Windows Service Bus. Having issues with registrations and I have been looking for more samples to see if configuration has changed.

Nimbus.Configuration.PoorMansIocContainer.DependencyResolutionException : No registration for type Nimbus.Transports.WindowsServiceBus.Filtering.ISqlFilterExpressionGenerator

The intent is to move to different transport but I just want to make sure everything compiles and runs with existing transport.

Hi guys , Im trying to use Nimbs window service bus , just wondering any service bus explorer tools available to view the queue and topic ?

@shreekannan try

A webui that uses nimbus under the hood

@shreekannan

Thanks @drewfreyling i'll try this

Im using windows service bus 2.1 and try to start the bus service uisng unity IOC Container. Not sure what is missing here. DependencyResolutionException: Failed to construct type
DependencyResolutionException: No registration for type Nimbus.Transports.WindowsServiceBus.Filtering.ISqlFilterExpressionGenerator

Kannan

@shreekannan

Ive fixed the dependency issue

Drew Freyling

@drewfreyling

@ma499 do you think it is worth cherry picking NimbusAPI/Nimbus#270

for v2

given v3 hasn't made its way onto nuget yet and with no .net core support (plus a major lack of v2 updates over the years even though fixes were merged), i'm questioning whether it is worth supporting this project anymore

Hi everyone, is this project still alive and what's cooking with v3 that started radio silence in 2016?

Shingi Mutandwa

@shingi

Anyone know how support for long running handlers is handled in v3?

@shingi

@uglybugger @DamianMac How is support for long running handlers handled in v3? Planning to upgrade an existing site which is using this feature in v2.

On Nimbus 2.0.0.98 in combination with Autofac 3.5.2 - I have an issue where my event is being handled multiple times (event handler is being instantiated multiple times) . I tried changing the event handler from IHandleMulticastEvent to IHandleCompetingEvent however the same problem occurs. Is this a known issue? Any workarounds?

@DamianMac @uglybugger ^^^

Drew Freyling

@drewfreyling

@flakey-bit are you reaching the message lock timeout?

unfortunately the thread still runs while a new message gets popped back on the queue

@KrugerRuaan_twitter see my message from earlier. might be time to fork!

Eddie Stanley

@flakey-bit

@drewfreyling reaching the message lock timeout was indeed the problem.

Drew Freyling

@drewfreyling

@flakey-bit what did you do to get around it?

so lets says you are trying to stitch together some pdfs (think 100s) and this always takes longer than the longest peeklock you can have in WSB (5 mins)

the messages will forever be popped back on the queue....

and if they are large messages and you are storing them on the file system you will run out of disk space :)

this sounds like a hypothetical but i can assure you it is not!

philtts

@philtts

Hey all .. we're getting this message repeatedly in production: "Lock for message c1e4f985949849b6812d55650bdc0def appears to have already expired so we're not dispatching it. Watch out for clock drift between your service bus server and DESKTOP-R6O92KC!"

Obviously we've checked the clocks and there is no drift. We're currently not able to pull any messages off the queue because of this. Anyone else come across this? Cheers.

Drew Freyling

@drewfreyling

I've only seen this when your sb nodes have clock drift. Check all the nodes?

@DamianMac

...and I'm alive! been making some changes. Sorry for radio silence, life happens

@drewfreyling you up for a coffee at some point? Would love to chat with you about what you're up to and how we can do this better

3.0 is on Nuget, there's a new sample app on github, have done a bunch of wiki updates with some more to come

.net standard / core support is definitely on the radar, and I've started on a ampq transport

Drew Freyling

@drewfreyling

@DamianMac definitely.

@drewfreyling

well this is interesting

wow

that's not one i've seen before

binupabraham

@binupabraham

Hi guys.. with ver 2.0.0.98, is there a way to retry sending commands after a delay?

Drew Freyling

@drewfreyling

Yes there is a .SendAfter extension on ibus

binupabraham

@binupabraham

Thanks @drewfreyling . If there is an error in the command handler (ex:smtp exception) and I want to retry the same command after 5 minutes , do I add the .SendAfter logic in the IInboundInterface.OnCommandHandlerError method?

Sorry I meant IInboundInterceptor.OnCommandHandlerError

Drew Freyling

@drewfreyling

Or just try catch and SendAfter in the handler body, up to you

Mustafa Arif

@ma499

Is there a way to set the message label when publishing using Nimbus?
