For this way of configuring input queue to work, you need to supply a correct configuration
section declaration in the <configSections> element of your app.config/web.config - like so:
<configSections>
<section name=""rebus"" type=""Rebus.Configuration.RebusConfigurationSection, Rebus"" />
<!-- other stuff in here as well -->
</configSections>
-and then you need a <rebus> element some place further down the app.config/web.config,
like so:
<rebus inputQueue=""my.service.input.queue"">
<rijndael key=""base64 encoded key""/>
</rebus>
Note also, that specifying the input queue name with the 'inputQueue' attribute is optional.
