This OPC UA reference implementation is targeting .NET Standard specification.

.Net Standard allows you develop apps that run on all common platforms available today, including Linux, iOS, Android (via Xamarin) and Windows 7/8/8.1/10 (including embedded/IoT editions) without requiring platform-specific modifications.

One of the reference implementations inside this project has been certified for compliance through an OPC Foundation Certification Test Lab to prove its high quality. Fixes and enhancements since the certification process have been tested and verified for compliance using the Compliance Test Tool (CTT) V1.04.

Furthermore, cloud applications and services (such as ASP.Net, DNX, Azure Websites, Azure Webjobs, Azure Nano Server and Azure Service Fabric) are also supported.

1. Fully ported Core OPC UA Stack and Libraries (Client, Server, Configuration, ComplexTypes & GDS assemblies).
2. Reference sample Servers and Clients.
3. X.509 certificate support for client and server authentication.
4. SHA-2 support (up to SHA512) including security profile Basic256Sha256 for configurations with high security needs.
5. Anonymous, username and X.509 certificate user authentication.
6. UA-TCP & HTTPS transports (client and server).
7. Folder & OS-level (X509Store) certificate-store support.
8. Sessions.
9. Subscriptions.
10. OPC UA Reference Server.
11. OPC UA Console Reference Server.
12. OPC UA Reference Client.
13. OPC UA Reference Server has been certified for compliance through an OPC Foundation Certification Test Lab. Fixes and enhancements since the certification process have been tested and verified for compliance using the Compliance Test Tool (CTT) Version 1.03.340.380.
14. An official OPC UA Nuget package of the core, client, server and configuration libraries is available for integration in .Net projects.

All the tools you need for .Net Standard come with the .Net Core tools. See here for what you need.

All required application certificates for OPC UA are created at the first start of each application in a directory or OS-level certificate store and remain in use until deleted from the store.

By default all sample applications are configured to register with a Local Discovery Server (LDS). A reference implementation of a LDS for Windows can be downloaded here. To setup trust with the LDS the certificates need to be exchanged or registration will fail.

1. Open the UA Reference.sln solution file using Visual Studio 2017.
2. Choose a project in the Solution Explorer and set it with a right click as Startup Project.
3. Hit F5 to build and execute the sample.

This section describes how to run the and NetCoreReferenceServer sample application.

Please follow instructions in this article to setup the dotnet command line environment for your platform. As of today .Net Standard 2.0 is required.

1. Once the dotnet command is available, navigate to the root folder in your local copy of the repository and execute dotnet restore UA Reference.sln. This command calls into NuGet to restore the tree of dependencies.

1. Open a command prompt.
2. Navigate to the folder Applications/NetCoreReferenceServer.
3. To run the server sample type dotnet run --project NetCoreReferenceServer.csproj -a.
   • The server is now running and waiting for connections.
