Remarks

This method creates a corresponding IDataStore object based on the default connection string (returned by the XpoDefault.ActiveConnectionString property) and defaultAutoCreateOption parameter and then creates a SimpleDataLayer object that wraps the created IDataStore object.

The value returned by this method can be used to initialize the XpoDefault.DataLayer property or passed to a Session object’s constructor.

When you have finished working with a data layer you need to dispose of it to release the resources allocated by the data layer.
