ODCTenantPoolSize

OutSystems Integration Studio extension that exposes two tenant‑pool forecasting actions for ODC Personal Editions:

• MssPersonalEditionPoolSizePredictionSSA_Get — per‑weekday Singular Spectrum Analysis (ML.NET).
• MssPersonalEditionPoolSizePredictionSARIMA_Get — Box‑Jenkins SARIMA(p, d, q) × (P, D, Q, s), with an optional SARIMAX exogenous regressor derived from a z‑score test, built on top of MathNet.Numerics.

Both actions consume an RLPersonalEditionRequestRecordList of historical daily counts per region and return a forecast list with one row per (prediction date, region).

Prerequisites

• Visual Studio 2022 (or the .NET Framework 4.8 build tools) with MSBuild.
• OutSystems Integration Studio, for repackaging the extension into an .xif for publication. The platform‑side DLLs in Source/NET/Bin/ are reproduced by Integration Studio when you open the project; they are not tracked.

Building

cd Source/NET
nuget restore .\ODCTenantPoolSize.sln          # or `dotnet restore`
msbuild .\ODCTenantPoolSize.sln /p:Configuration=Release

The build emits OutSystems.NssODCTenantPoolSize.dll in Source/NET/Bin/ and copies the ML.NET win‑x64 native runtimes (MklImports.dll, CpuMathNative.dll, …) alongside it via the CopyMlNativeRuntimes MSBuild target defined in the .csproj.

.csproj regeneration warning

Integration Studio rewrites Source/NET/ODCTenantPoolSize.csproj on every Source‑code‑edit cycle. After regeneration, the FORECAST_DEPENDENCIES block (NuGet PackageReferences for Microsoft.ML, Microsoft.ML.TimeSeries and MathNet.Numerics, plus the CopyMlNativeRuntimes and ExcludeUnusedMlAssemblies targets) and the additional <Compile Include> entries for the forecasting source files must be reapplied. The block is preserved verbatim in the committed .csproj for that purpose.
