How to synchronously invoke a Business Operation from a classMethod without using a business service

Hello,

I am trying to find out if it is possible to invoke a Business Operation from a class method without using a Business Service.

I have the following code but was wondering if it can be done without using a Service.

s tService = ##class(Ens.Director).CreateBusinessService("Business Service Name",.service)
d service.SendRequestSync("targetBusinessOperation",request,.response)

I tried creating an instance of Ens.BusinessOperation and then call SendRequestSync but that didn't seem to work.

Any better ideas anyone? 

Thanks in advance.
