Parameters

Name	Type	Description
connection	IDbConnection	An object implementing the IDbConnection interface that represents an open connection to a data source.
autoCreateOption	AutoCreateOption	An AutoCreateOption value that specifies which operations should be performed when a data store is accessed for the first time.

Returns

Type	Description
IDataLayer	The created SimpleDataLayer object.

Remarks

This method creates a corresponding IDataStore object based on the specified connection and autoCreateOption parameters and then creates a SimpleDataLayer object that wraps the created IDataStore object. The metadata information used to create the data layer is obtained via the XpoDefault.GetDictionary method.

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.
