It looks like you have the right idea.  The DataSources is a shared collection, so you could create a base BO that all of your business objects inherit from.  In the constructor of the BaseBO, you could then test to see if the connection string(s) have been created:

But it looks as though you were already heading down the right road

I am looking for an approach to Datasource access with using a Strataframe BO in another plug-in enviroment ( these enviroments dynamically load assemblies using CreateInstance ).   The BO may be called from a Form or User Object and configuration of the Datasource connection string would be done prior to usage.  Maybe Ben or Trent have an idea here.   My question is where should I have the Datasource logic placed?  

The first option that came to mind is to modify my base business object to instantiate the Datasource if it is not found.  I can do this through a shared class, module, etc. if necessary.  This would work like the way the AppMain functions and loads the Exeception and Datasource objects.   Any comments, ideas, etc?

Thanks,

Richard
