A cached data store provider (an ICachedDataStore implementation) for client applications transferring data via WCF.
Namespace : DevExpress.Xpo.DB
Assembly : DevExpress.Xpo.v25.2.dll
NuGet Package : DevExpress.Xpo

Public Class CachedDataStoreClient
Inherits CachedDataStoreClientBase(Of ICachedDataStoreWarpService)
CachedDataStoreClient objects are automatically created to maintain a cache (DataCacheNode) on the client side when you create a data layer via the XpoDefault.GetDataLayer method call and pass a connection string to a service (an ICachedDataStoreService implementor, such as a CachedDataStoreService descendant) as a method parameter.
// Sample WCF service connection string.
string connectionString = "http://localhost:64466/Service.svc";
// GetDataLayer automatically creates
// a cached data store provider (and a cache) based on the connection string.
XpoDefault.DataLayer = XpoDefault.GetDataLayer(connectionString, AutoCreateOption.DatabaseAndSchema);
XpoDefault.Session = null;
' Sample WCF service connection string.
Dim connectionString As String = "http://localhost:64466/Service.svc"
' GetDataLayer automatically creates
' a cached data store provider (and a cache) based on the connection string.
XpoDefault.DataLayer = XpoDefault.GetDataLayer(connectionString, AutoCreateOption.DatabaseAndSchema)
XpoDefault.Session = Nothing
If you are going to create a cache hierarchy at the client, you can manually create CachedDataStoreClient objects as shown below.
// Specifying the name of the endpoint in the client application's configuration file.
string bindingName = "...";
// Creating a cache (a node starting a cache hierarchy at the client).
DataCacheNode node = new DataCacheNode(new CachedDataStoreClient(bindingName));
// Checking connection.
node.ProcessCookie(DataCacheCookie.Empty);
XpoDefault.DataLayer = new SimpleDataLayer(node);
XpoDefault.Session = null;
' Specifying the name of the endpoint in the client application's configuration file.
Dim bindingName As String = "..."
' Creating a cache (a node starting a cache hierarchy at the client).
Dim node As New DataCacheNode(New CachedDataStoreClient(bindingName))
' Checking connection.
node.ProcessCookie(DataCacheCookie.Empty)
XpoDefault.DataLayer = New SimpleDataLayer(node)
XpoDefault.Session = Nothing
