  Hi! I'm having the following dilemma on how to handle multi threaded operations. I have to handle the case of multiple of calls per second that must be executed asynchronously. Creating a new Threading.Thread object is a simple solution, however I dont think its the best choise, since thread creation and destruction overhead would be too much.

  I have re-implemented an IFormatter for the project NGrid . The code can be seen on this page . I have found such tasks very tedious with the current design of the serialization framework in .Net 1.1. Here below, the list of the hard points.
