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

• 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

New features

• 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
