RabbitMQ.Clicent.Framing v0_9_1 does not exist in namespace?

When I attempted to build my VS solution containing the unmodified Github HangFire source code, I got the following error:

Error 6 The type or namespace name ‘v0_9_1’ does not exist in the namespace ‘RabbitMQ.Client.Framing’ (are you missing an assembly reference?) C:\Users\Jerry_Dev\Documents\GitHub\Hangfire\src\Hangfire.SqlServer.RabbitMq\RabbitMqFetchedJob.cs 39 60 Hangfire.SqlServer.RabbitMq
