Does Discountasp.net support hosting of NServiceBus applications? As far as I know NServiceBus uses MSMQ. Here is some information on hosting NServiceBus.
As long as the .dll's do not need to be registered in Windows, you can upload them to your /bin directory. Regarding MSMQ, this is from the NserviceBus site: "During the time that the Connected Systems Division at Microsoft was developing Indigo (now known as WCF), there was the intention to replace MSMQ with something new. 2 years later, the effort to replace MSMQ was abandoned and MSMQ was integrated into the standard WCF model and configuration. " And we support WCF.
