What is the difference between writtinig
System.Runtime.InteropServices.Marshal.ReleaseComObject(ob)

and writting ob=null ?. What will happen with my object in memory after
those operations?

The former decrements the internal reference count of the RCW and
possibly releases the underlying COM object.

The latter just sets your reference to the object to null, it doesn't
affect the object itself in any way (though it may become eligible for
garbage collection some time in the future).

It depends on of there are other references to the same object.
