If you mean something similar to the EasyOpcNetDemo application, then its A&E counterpart has never existed before.
For A&E, example code is available for specific individual methods/objects, and they are all in the main Examples solution, under Console\DocExmaples. They are:
- SWToolbox.TOPServer_AE.Main.cs
- _AEAttributeElement.Properties.Main.cs
- _AECategoryElement.Properties.Main.cs
- _AEConditionElement.Properties.Main.cs
- _EasyAEClient.AcknowledgeCondition.Main.cs
- _EasyAEClient.BrowseAreas.Main.cs
- _EasyAEClient.BrowseServers.Main.cs
- _EasyAEClient.BrowseSources.Main.cs
- _EasyAEClient.ChangeEventSubscription.Main.cs
- _EasyAEClient.CreateSubscriptionFilter.Main.cs
- _EasyAEClient.GetConditionState.Main.cs
- _EasyAEClient.MultipleNotifications.Main.cs
- _EasyAEClient.QueryEventCategories.Main.cs
- _EasyAEClient.QuerySourceConditions.Main.cs
- _EasyAEClient.RefreshEventSubscription.Main.cs
- _EasyAEClient.SubscribeEvents.CallbackLambda.cs
- _EasyAEClient.SubscribeEvents.Main.cs
- _EasyAEClient.UnsubscribeAllEvents.Main.cs
- _EasyAEClient.UnsubscribeEvents.Main.cs
- _EasyAENotificationEventArgs.AttributeValues.Main.cs
In addition, there are following projects in the Examples solution that deal with A&E:
- Console\ConsoleEvents
- Console\XmlEventLogger
Plus some examples for Reactive Programming and for StreamInsight.
It is true that currently, the amount/scope/level of examples that are available for OPC A&E is not as great as for OPC-DA. If a specific example is needed, I can fill in the gap and then make it part of the standard set - just let me know.
