AWS Lambda Durable Execution SDK for .NET is now generally available

AWS announces the general availability of the AWS Lambda Durable Execution SDK for .NET, allowing C# developers to build resilient, long-running workflows using Lambda durable functions. With this SDK, developers can create multi-step applications such as payment processing pipelines, AI agent orchestration, and human-in-the-loop approvals directly in their applications without implementing custom progress tracking or integrating external orchestration services. Lambda durable functions extend Lambda's event-driven programming model with operations that automatically checkpoint progress and pause execution for up to a year while waiting for external events. The AWS Lambda Durable Execution SDK for .NET provides an idiomatic C# experience for building with Lambda durable functions, including steps for progress tracking, callback integration for human and agent-in-the-loop workflows, durable invocation for reliable function chaining, and waits for efficient suspension. The SDK installs from NuGet into the .NET toolchain used today, and the local testing emulator in the SDK enables developers to build and debug locally before deploying to production.
