Without a working example it's hard to tell what went wrong. My guess are 2 things:

1. As multi-threading or async seems to be used, SmartSettings.IsThreadSafeMode = true must be set. The default is false.
2. Smart.Format(...) methods can't be used in this case, as they use a static SmartFormatter instance. A new SmartFormatter must be created for each thread.

See the Wiki and the hint in the README for details.

Thanks for the info about the thread safety I guess it's a 3.0 Feature that was added Right??

Yes I'm working in a Highly Multi threaded Environment will apply the fix and feedback the performance updates

We just published release v3.1.0:

• SmartSettings.IsThreadSafeMode = true is the default
• Static Smart methods like Smart.Format(...) can be used also with async / multi-threading
