hi Folks,

i am working for .net Support. we have one .net project using Microsoft Windows Workflow Fundation(WWF).

I am new to Windows Workflow Fundation(WWF).
In Production we are getting "Object reference not set to an instance an object ". we could not able to replicate in DEV environment.

we are suspecting the cause is because of Workflow. No where we not able find the rootcause.
please help me to identify either some service need to enable related to workflow or what needs to do.
