Title:
.NET Stack and Sample Applications
Description:
Open Source:
This code base is available as an open source project on GitHub. This allows OPC UA to be used for trial applications, prototypes, or research projects by non-members.
Latest stable versions are under Releases in the GitHub repository. Stable snapshots from the period before the open source trnsition are provided for download below.
The .NET Stack contains the core OPC UA stack and many, many reference examples, including:
- .NET based source code and numerous helper classes for use with Visual Studio
- Many Client/Server reference implementations for Aggregation, Alarms&Conditions, DataAccess, Events, HistoricalData, HistoricalEvents, InformationModel, Methods, UserAuthentication and Views
- Documentation for the API, reference applications, and general concepts for OPC UA configuration and security
- Revision history
- Model compiler
