This sample demonstrates the F#-like build and reference model for DotPython:

• PricingRules.dpyproj compiles pricing.py into a managed assembly.
• pricing.pyi declares the typed public API exposed to .NET callers.
• Consumer.csproj references the DotPython project with an ordinary ProjectReference.
• The console application creates one explicit DotPythonHost lifetime owner and retrieves the generated module like a normal typed service.
• ASP.NET Core and Generic Host applications can instead use AddDotPythonManaged().AddDotPythonModule(PricingModule.Registration) for DI-managed ownership.

Run it from the repository root:

dotnet run --project samples/DotPython.ProjectReference/Consumer/Consumer.csproj

The expected output is 126.

The sample imports DotPython.Sdk directly from this repository because the SDK package has not been published yet. A packaged project instead uses the additive SDK declaration documented in the root README and pins its version through global.json.
