1.5.377.21

Breaking Changes:

Server

  • IMonitoredItem Interface extended & used instead of MonitoredItem Class
  • New ISession Interface instead of Session Class
  • ISesssionManager, ISubscriptionManager, ISubscription & IServerInternal interfaces extended

Core

  • ICertificateStore Async Methods now have async suffixes, old names deprecated
  • All obsolete Methods removed

Client

  • All sync methods are now marked as deprecated
  • DataTypeDictionaries moved into the ComplexTypes Package. If the helper methods of the Session were used we recommend to use the complex type system as a replacement that can handle all servers from OPC UA Spec 1.0 - 1.0.05.
  • NodeCache now has an async interface (to have access to the ITypeTable interface use the .TypeTree property or AsNodeTable method

ApplicationInstance

  • Methods Returning a task have asyny suffixes

GDS Client

  • sync apis marked as deprecated

Bug Fixes:

Server

  • Fix Subscription Keepalive being sent on first publish
  • Handle unsent requests on closed SecureChannel to be sent on new channel of the same session

Client

  • Disable Subscription cleanup if subscriptions are being created
  • Fix subscription leaking due to not completed PublishResponseMessageWorkerAsync tasks
  • Fix subscription leaking due to not completed PublishResponseMessageWorkerAsync tasks

New features:

Server

  • Support for async method calls by implementing IAsyncNodeManager interface (see ConfigurationNodeManager for an example usage)
  • New Task based Request Queue
  • New generated Code with async Method Call handlers & async Service Calls
  • New extended CustomNodeManager with support for SamplingGroup Mechanism

GDS Client

  • exposes async APIS and marks sync apis as deprecated

Client

  • New LRU NodeCache added & used in ComplexType System
