Hi All, What is 'userState' in 'protected virtual Task SaveAsync(object userState, bool isSync)'? I am trying to override SaveAsycn() for a RootCollection.

kind regards

The userState parameter is a standard mechanism used by many async APIs to allow the caller to pass arbitrary data through the async process. CSLA itself ignores this value entirely.

So you can pass whatever you'd like through that parameter in case you want to use it in an override of SaveAsync, and it also flows into the virtual OnSaved method and the Saved event (via its args).
