• v1.0

sdk-csharp

.NET Standard 2.0 (C#) SDK for CloudEvents

The CloudNative.CloudEvents package provides support for creating, encoding, decoding, sending, and receiving CNCF CloudEvents. Most applications will want to add dependencies on other CloudNative.CloudEvents.* packages for specific event format and protocol binding support. See the user guide for details of the packages available.

A few gotchas highlighted for the impatient who don't usually read docs

1. The CloudEvent class is not meant to be used with object serializers like JSON.NET. If you need to serialize or deserialize a CloudEvent directly, always use a CloudEventFormatter such as JsonEventFormatter.
2. Protocol binding integration is provided in the form of extensions and the objective of those extensions is to map the CloudEvent to and from the respective protocol message, such as an HTTP request or response. The application is otherwise fully in control of the client. Therefore, the extensions do not add security headers or credentials or any other headers or properties that may be required to interact with a particular product or service. Adding this information is up to the application.

Changes since 1.x

From version 2.0.0-beta.2, there are a number of breaking changes compared with the 1.x series of releases. New code is strongly encouraged to adopt the latest version rather than relying on the 1.3.80 stable release.

The stable 2.0.0 version was released on June 15th 2021, and all users are encouraged to use this (or later) versions.

A more details list of changes is provided within the documentation.

Community

• There are bi-weekly calls immediately following the Serverless/CloudEvents call at 9am PT (US Pacific). Which means they will typically start at 10am PT, but if the other call ends early then the SDK call will start early as well. See the CloudEvents meeting minutes to determine which week will have the call.

Each SDK may have its own unique processes, tooling and guidelines, common governance related material can be found in the CloudEvents community directory. In particular, in there you will find information concerning how SDK projects are managed, guidelines for how PR reviews and approval, and our Code of Conduct information.
