Transfer Data via WCF Services

• Oct 10, 2023

XPO allows you to easily transfer data over the wire in your distributed applications with WCF services using specially developed IDataStore, ICachedDataStore and ISerializableObjectLayer providers. You can choose one for the server application (based on your data store access method) and expose it with the WCF service. In most cases, all you have to do is derive your service from a corresponding XPO service class, modify service binding settings, and pass the service’s URL to your client application.

The following table summarizes the information on classes and interfaces available for use with WCF services.

Data Store Implementation	Service Class *	Client Class	Examples
IDataStore	DataStoreService	DataStoreClient DataStoreClientAsync	How to connect to a remote data service instead of using a direct database connection How to connect to remote data store and configure WCF end point programmatically
ICachedDataStore	CachedDataStoreService	CachedDataStoreClient CachedDataStoreClientAsync	How to create a data caching service that helps improve performance in distributed applications
ISerializableObjectLayer	SerializableObjectLayerService SerializableObjectLayerProxyBase (auxiliary)	SerializableObjectLayerServiceClient SerializableObjectLayerClient (auxiliary)	How to implement a distributed object layer service working via WCF

* Note that service classes are not supported in .NET Core 5+. You can connect client classes for these platforms to the service classes hosted in .NET Framework applications.
