Deprecation of Coralogix .NET SDK
Published: January 12, 2026
Effective: June 30, 2026
Deprecation notice
As part of our continued investment in open standards and long-term observability best practices, Coralogix will deprecate the Coralogix .NET SDK on June 30, 2026.
The Coralogix .NET SDK is deprecated in favor of the OpenTelemetry .NET SDK, which is now the recommended and supported approach for collecting logs, metrics, and traces from .NET applications.
Action is required to ensure continued support and compatibility.
Why this is happening
The observability ecosystem has converged on OpenTelemetry as the industry standard for telemetry collection. Maintaining a proprietary SDK alongside OpenTelemetry creates duplication and limits access to new capabilities.
By standardizing on OpenTelemetry, Coralogix can provide:
- A vendor-neutral, CNCF-backed standard
- Unified collection of logs, metrics, and traces
- Faster access to new ecosystem features and integrations
- Long-term stability and community-driven innovation
- Consistent configuration across languages and platforms
What’s affected
The following Coralogix-maintained .NET SDKs are deprecated:
Coralogix.SDK(for .NET Framework)CoralogixCoreSDK(for .NET Core)
These SDKs may currently be used in:
- .NET Framework or .NET Core applications
- Custom logging implementations using
CoralogixLogger - Applications configured with
CORALOGIX_LOG_URL - CI/CD pipelines or deployment scripts that install Coralogix NuGet packages
After the effective date, these SDKs will no longer be supported or maintained.
What you need to do
Migrate to OpenTelemetry for .NET
Replace the Coralogix .NET SDK with OpenTelemetry .NET instrumentation.
The OpenTelemetry .NET SDK is stable and fully supported by Coralogix for:
- Logs
- Metrics
- Traces
You can choose between:
- Auto-instrumentation (zero code changes)
- Manual instrumentation (full control and customization)
Follow the official guide here:
.NET OpenTelemetry Instrumentation
Update endpoint configuration
OpenTelemetry uses Coralogix regional ingress endpoints:
Update authentication
Replace legacy SDK authentication with OpenTelemetry headers:
- New:
Authorization: Bearer <your-api-key>
Ensure all environment variables, containers, and scripts are updated accordingly.
What will happen after June 30, 2026?
- The Coralogix .NET SDK will no longer be supported
- No bug fixes, updates, or security patches will be provided
- Compatibility with newer .NET versions is not guaranteed
- Support requests related to the deprecated SDK may be declined
Existing applications may continue to function, but migration is strongly recommended.
