Could not load type ... from assembly

I have my application which compiles and runs successfully on my development box hangfire, but once I deploy it to the QA hangfire server, I get the error on the dashboard that "Could not load type … from assembly. I will appreciate any insight on what is responsible for this error.

You didn’t deploy the dll that contains the types that Hangfire is looking for. Something is wrong with your project references or your deploy process. Compare the bin directory from your local machine to the bin directory on the QA Server.
