Classes

Name Description
AccessConnectionProvider Implements data-aware operations for working with MS Access databases.
AccessConnectionProviderMultiUserThreadSafe Implements an MS Access connection provider that can be used in multi-user and multi-threaded applications.
CachedDataStoreClient A cached data store provider (an ICachedDataStore implementation) for client applications transferring data via WCF.
CachedDataStoreClientAsync A cached data store provider that client applications can use to asynchronously work with the data source via WCF.
CachedDataStoreClientAsyncBase<TContractType>
CachedDataStoreService The base class for WCF services providing access to data via cached data stores (objects implementing the ICachedDataStore interface).
DataStoreClient A data store provider (an IDataStore implementation) for client applications transferring data via WCF.
DataStoreClientAsync A data store provider that client applications can use to asynchronously work with the data source via WCF.
DataStoreService The base class for WCF services providing access to data directly via data store providers (IDataStore implementors).
FirebirdConnectionProvider Implements data-aware operations for working with a Firebird database.
InMemoryDataStore Stores persistent objects in memory. Intended for testing environment.
MSSqlConnectionProvider Implements data-aware operations for working with an MS SQL Server or MS SQL Azure database.
OleDBConnectionProvider Implements the base functionality for providers that connect to OLE DB data sources.
OperationResult The result of an operation performed by the DataStoreService, CachedDataStoreService, or SerializableObjectLayerService.
OperationResult<T> The result of an operation performed by the DataStoreService, CachedDataStoreService, or SerializableObjectLayerService.
PostgreSqlConnectionProvider Implements data-aware operations for working with a PostgreSQL database.
SerializableObjectLayerProxyBase The base class for SerializableObjectLayer proxies.
SerializableObjectLayerService The base class for WCF services providing access to data via distributed object access layer (ISerializableObjectLayer implementors).
SerializableObjectLayerServiceClient A distributed object access layer (an ISerializableObjectLayer implementation) for client applications transferring data via WCF.
ServiceBase The base class for XPO WCF services.
ServiceExceptionEventArgs Arguments, passed to the ServiceBase.GlobalServiceExceptionThrown and ServiceBase.ServiceExceptionThrown events.

Interfaces

Name Description
