Code Generation Summary — Unit 1: Backend Dual-Instance Hosting

Created

• src/SlpModularCms.Core/Hosting/ModuleOrchestrator.cs
• src/SlpModularCms.Core/Hosting/ServiceCollectionExtensions.cs
• src/SlpModularCms.Core/Hosting/ApiPrefixConvention.cs
• src/SlpModularCms.Api.Slave/SlpModularCms.Api.Slave.csproj
• src/SlpModularCms.Api.Slave/Program.cs
• src/SlpModularCms.Api.Slave/appsettings.json
• src/SlpModularCms.Api.Slave/appsettings.Development.json
• src/SlpModularCms.Api.Slave/appsettings.local.json.example
• src/SlpModularCms.Api.Slave/Properties/launchSettings.json
• src/SlpModularCms.Core.Tests/Hosting/ApiPrefixConventionTests.cs (relocated from Modules.Identity.Tests)
• src/SlpModularCms.Core.Tests/Hosting/ModuleOrchestratorTests.cs (relocated from Modules.Identity.Tests)

Modified

• src/SlpModularCms.Core/SlpModularCms.Core.csproj — added Asp.Versioning.Mvc and Microsoft.AspNetCore.OpenApi package references
• src/SlpModularCms.Api/Program.cs — using statements updated to SlpModularCms.Core.Hosting (no logic change)
• src/SlpModularCms.Modules.Identity.Tests/SlpModularCms.Modules.Identity.Tests.csproj — removed ProjectReference to SlpModularCms.Api (no longer needed; the only tests using it were relocated to Core.Tests)
• SlpModularCms.sln — added SlpModularCms.Api.Slave project entry, build configurations, and solution-folder nesting under src

Deleted

• src/SlpModularCms.Api/Infrastructure/ModuleOrchestrator.cs (moved to Core)
• src/SlpModularCms.Api/Extensions/ServiceCollectionExtensions.cs (moved to Core)
• src/SlpModularCms.Api/Infrastructure/ApiPrefixConvention.cs (moved to Core)
• src/SlpModularCms.Modules.Identity.Tests/Infrastructure/ModuleOrchestratorTests.cs (relocated to Core.Tests/Hosting/)
• src/SlpModularCms.Modules.Identity.Tests/Infrastructure/ApiPrefixConventionTests.cs (relocated to Core.Tests/Hosting/)

Notes / Deviations from Plan

• Discovered during generation that SlpModularCms.Modules.Identity.Tests referenced SlpModularCms.Api solely to test ModuleOrchestrator/ApiPrefixConvention — an existing layering quirk, not something this feature introduced. Since those classes now live in Core, their tests were relocated to Core.Tests/Hosting/ (which already references Core and already has all needed test packages: FluentAssertions, NSubstitute, xunit). This removed the odd cross-project test dependency as a side effect.
• ServiceCollectionExtensions.cs needed explicit using Microsoft.Extensions.Configuration;, using Microsoft.Extensions.DependencyInjection;, using Microsoft.AspNetCore.Builder;, and using Microsoft.AspNetCore.Http; after the move — SlpModularCms.Api is a Microsoft.NET.Sdk.Web project (implicit ASP.NET Core usings), while SlpModularCms.Core is a plain Microsoft.NET.Sdk project, so these weren't implicitly available.
• Left Asp.Versioning.Mvc and Microsoft.AspNetCore.OpenApi package references in place on SlpModularCms.Api.csproj even though they're now also referenced transitively via Core — removing them was optional per the plan and the build succeeds either way; left as-is to minimize unrelated diff.

Verification Performed

• dotnet build SlpModularCms.sln — succeeds, no errors.
• dotnet test SlpModularCms.sln — all 4 existing test projects pass unchanged: Core.Tests (54), Modules.Availability.Tests (60), Modules.Identity.Tests (37), Modules.Master.Tests (42).
• Manually ran dotnet run --launch-profile https in both SlpModularCms.Api and SlpModularCms.Api.Slave:
  • Master (SlpModularCms.Api): discovers and loads all 3 modules — Availability, Identity, Master.
  • Slave (SlpModularCms.Api.Slave): discovers and loads exactly 2 modules — Availability, Identity. Master is correctly excluded.
• Full end-to-end run (requiring a real local SQL Server/localdb instance and manual "Add CMS Instance" registration) is deferred to Build and Test / Unit 2, per the plan.
