System.ArgumentException: The path is not of a legal form when invoking NServiceBus via Hangfire task

Question

I get the below error when I try to invoke NServiceBus/Rabbit MQ via a Hangfire Task I have tried updating the .NET Framework version from 4.5.2 to 4.6.1

Not sure what is it that I'm doing wrong here? I keep getting this error However, when I run this locally (via a Test Project), then the message is successfully placed on the Service Bus (am able to see it on the Service Endpoint)

    System.AggregateException
One or more errors occurred.

Can you find out what the value of `typeof(NServiceBus.Endpoint).Assembly.Location` and `typeof(NServiceBus.RabbitMQTransport).Assembly.Location` are when run from inside your Hangfire task? — Brandon Ording, Jun 11 '18 at 23:08
@SeanFarmar no have checked the Connection string, also, when I try to put a message to the NServiceBus via the Test Project it works (with the same connection string) — user280868, Jun 13 '18 at 00:20
@SeanFarmar yes, Barndon's suggestion made us look in the direction of the below posted answer — user280868, Jun 19 '18 at 06:13

We resolved the issue by placing the NService Bus files (including DLLs) on the same server where the Hangfire Tasks were located and add the references to NService Bus on the Hangfire task solution
