See the RTI® Connext® Core Libraries What's New and Core Libraries Release Notes at https://community.rti.com/documentation.

Supported Platforms

The Connext C# API is supported on .NET 5 (and newer). It is also supported on .NET Core 2.1 (and above) and .NET Framework 4.8.3 (and above).

For information on Connext C# API supported platforms, see the Platform Notes. Find the ".NET (C#) API" section in the Linux®, macOS®, and Windows® chapters.

Installation

See the Getting Started Guide to install the Connext DDS C# API and build and run your first application.

To work with Unity, see this tutorial.

Limitations in this Release

Limitations related to the Connext DDS API

• The Distributed Logger API is not yet available. However a custom handler for RTI Connext log messages can be used to redirect log messages using the Rti.Config.Logger.MessageLogged event.
• The FlowController class is not implemented, but FlowControllers can be configured with the Rti.Dds.Core.Policy.Property QoS policy. See Writing data and instances. (CORE-11388)
• The TopicQuery class is not implemented. TopicQuery can be enabled on the DataWriter with the Rti.Dds.Core.Policy.TopicQueryDispatch QoS policy, but it can't be used on the DataReader. (CORE-11386)
• The interface to implement custom Content Filters is not supported. The built-in filters (SQL and String MATCH) are supported. (CORE-11388)

Limitations related to the IDL-to-C# code generation

• Arrays of sequences cannot be used unless the sequence is aliased using a typedef. Otherwise the array is ignored. (CODEGENII-1504)
• The @external annotation is not supported (it is ignored).
• The @csharp_mapping annotation, which allows customizing some aspects of the IDL-to-C# mapping, is not supported. (CODEGENII-1498, CODEGENII-1499)

Other limitations

• Most classes and methods in this API reference provide only brief descriptions and refer to their counterpart in the RTI Connext C API for their full description.
• For Red Hat® Enterprise Linux® 9 or Ubuntu® 22.04 and higher platforms: To use the Connext DDS C# API you must use .NET 6 or higher. (.NET 5 is no longer supported by these distributions.)

Legacy .NET API

The previous .NET API and IDL binding to C++/CLI was deprecated in 6.1.0 and removed in 7.1.0.

The 6.1.0 migration guide provides useful information for developers of the legacy .NET API.
