Hi Timothy,
I am glad that at last you resolved your problem.
I think you can create a new project and serialize some class objects
that contain some thread objects.
If the problem still arise, I think the problem must be related to your
IDE,
otherwise, it is related your application achitecture.
For you question of best solution, I do not quite certain, because I am
also
new to the .net remoting, I have not much experience on it.
Best regards,
Jeffrey Tan

| Hi Jeffrey, I have no clue why this happens. The exact message i get is :
| The type System.Threading.Thread in Assembly mscorlib, Version=1.0.5000.0,
| Culture=neutral, PublicKeyToken=b77a5c561934e089 is not marked as
| serializable.
|
| This may be due to some other underlying problem, but I am not sure what
it
| is. I solved the issue by making the class inherit from
MarshalByRefObject,
| I am not sure if this is the best solution.
|
| Thanks for your help!
