HttpContext.Current is not available to set the current SendContext

[Krzysztof Koźmic]

Hi,

I have an IIS hosted WCF service that gets the exception with message
mentioned above.

It has AspNetCompatibilityRequirementsMode.Required, but the exception
occurs in InboundMsmqTransport, in using(context.CreateScope()) call on
my foo_control_subscriptions queue.

I'm not sure I understand it enough, but it seems to me that there's an
assumption that if the bus is used from an app hosted in IIS the
HttpContext is always available and for some reason in this particular
case (managing subscribers) it assumption seems to be wrong.

Am I missing something, can I somehow workaround this?

I'm running latest build from TeamCity

Chris wrote this stuff, I think he'll have to comment on it; I'm not
sure here. I don't want you to think that I didn't see when I'm
answering your other stuff. I've never bothered using a bus in the
scope of a web service, it's always been one-way inbound message
writing.

This is broken in the NuGet package, but has been fixed in the develop branch. I'll likely put another beta on NuGet before the weekend.

[Krzysztof Koźmic]

I'm not using the nuget - I'm on the build from TeamCity and it does
certainly still occur (in the MassTransit package (build 2.0.0.395)).
Should I be using MassTransit (develop) build 2.0.0.68 instead?

What's the difference between them?
I'd appreciate an official build with the fix, some people on my team
strongly oppose using non-release builds.

cheers,
Krzysztof

[Krzysztof Koźmic]

I just tried to get the develop version from teamcity to test that, but
the build has no artifacts #sadpanda

Looks like the build failed, but it didn't get picked up by TeamCity as failed. Ugh.

[Krzysztof Koźmic]

I just tried the latest build from 30minutes ago and this one is not
working at all.

Yes - the exception is gone but the message never makes it to the
receiver. There's no exception or no other indication what might be wrong.

Krzysztof

[Chris Patterson]

When you say not working at all, what does that mean?

Also, if you could provide a log4net output of the test you performed, that would give some indication of what is happening.

Using the WebRequestReply sample, I've verified that it works in a web context, so I'm not sure what else could be going on without some logs.

[Krzysztof Koźmic]

Hi,

not working as in the message does not get posted/received. Not too sure
at which point it's failing.

I'll try to get logs on monday.

cheers,
Krzysztof

[Chris Patterson]

If you can throw the sample code up on GitHub or something, I could work it into a sample for WCF usage and use it to verify the transactional functionality within WCF. I don't know a whole lot about WCF though, I've managed to avoid it quite well.

[Krzysztof Koźmic]

sigh,

I was afraid you were going to ask for that. Getting a full reproduction
of the setup (WPF client talking to IIS hosted WCF service which posts a
message via MT to console app (eventually windows service)) might take
some time...

I'll see if I can find some time to do that on monday.

[Chris Patterson]

Which is why a log is the easier solution. :)

[Krzysztof Koźmic]

:) most certainly

[David Christiansen]

Hi All,

I don't know if it helps but I have created a 'blank' sample solution that includes WCF client / server with the startings of MassTransit integration here: 

https://github.com/DavidChristiansen/MassTransit-WCFRequestResponseSample

It really is a blank canvas but should hopefully make things a bit quicker to get a WCF/Castle/NH/MassTransit Request-Response sample pulled together.

Also, as a small test, I set the HttpContext.Current manually before
the call to Subscribe:

TextWriter output = new StringWriter();
HttpContext.Current = new HttpContext(new HttpRequest("", "http://
localhost", ""), new HttpResponse(output));

Not sure if that proves anything, but may help?

I'm have a similar issue, I have just got the latest bins and I'm
trying out MassTransit for the first time - I'm also a newbie to MSMQ,
so it could be me being stupid. I'm not sure why an HttpContext would
be needed for messaging? I am not using WCF, I simply have a web-
application which I want to handle messages in the background, I am
creating the bus and subscribing in the Application_Start (so the
HttpContext doesn't exist yet).

This is the stack-trace:

sbc.VerifyMsmqConfiguration();
sbc.UseMulticastSubscriptionClient();
sbc.ReceiveFrom(name);
});

Then when I subscribe I get the exception:

bus.SubscribeHandler<T>(handler);

Ok, got the latest using NuGet and all is good. Move along now... ;-)

[Chris Patterson]

I was going to say, from that call stack, I knew that was the old build. :)

Glad you got it working!
