From ec64222d540d9876f9f8ad4de8515692eb24797f Mon Sep 17 00:00:00 2001 From: Ninja Date: Thu, 25 Jun 2026 16:30:14 +0100 Subject: [PATCH 01/12] Add SourceFlow.Cloud.Azure project (v2.0.0) with Service Bus integration Pulls the Azure Service Bus cloud extension and its test suite from the cloud-support branch onto azure-cloud (branched from the released v2.0.0 master) and wires them into the solution. - src/SourceFlow.Cloud.Azure: builds clean against master's v2.0.0 core - tests/SourceFlow.Cloud.Azure.Tests: 31 unit tests passing - Fix idempotency DI: register InMemoryIdempotencyService as Singleton (+ cleanup hosted service) to match AWS. Scoped registration recreated the in-memory dedup store per message scope, defeating deduplication and acting as a captive dependency for the singleton listeners. - CI: Azure-Build.yml runs build + unit tests + pack, and an integration job against the Azure Service Bus emulator (+ SQL Edge), the Azure equivalent of the AWS LocalStack pipeline. --- .github/azure-emulator/Config.json | 62 ++
