Constantly getting The type `Class` does not contain a method with signature `MethodName'

Hi,

i’m using hangfire to run some background jobs,

About 90% of the time, when I enqueue a new job I get and InvalidOperationException with the detail The type Classname does not contain a method with signature `MethodName’

This is extremely frustrating as on the off-chance the job fires and the method signature is picked up.
