Why should you care?

You use this to build portfolio proof — a full vertical slice you can demo, deploy, and explain in interviews.

See it live — copy this example

Create a Web API project (dotnet new webapi), paste the code, then run dotnet run.

// TenantId from JWT claim → filter DbContext
// Gateway routes /api/v2/* to new Order.Api, /api/v1/* to legacy monolith

Run Example »

This lesson uses terminal or setup steps. Run commands on your computer — the live editor appears on coding lessons.

What happened?

• The example shows SaaS Multi-Tenant Platform wired into Order Service.
• Read each line, run it locally, then change one setting and observe what breaks or improves.
• That is how teams learn in production too — small experiments, not big bang rewrites.

Try it yourself

1. Open or create the ShopNest project area for Order Service.
2. Apply the SaaS Multi-Tenant Platform pattern from the lesson example.
3. Run dotnet build && dotnet run (or docker compose up when the lesson uses containers).
4. Change a string or route in the example and save — watch Swagger or the RabbitMQ Management UI update.
5. Break the code on purpose (remove a semicolon), read the error message, then fix it.

Remember

SaaS Multi-Tenant Platform connects to Order Service in ShopNest Cloud-Native. Practice by editing the example yourself — do not only read. Move on when you can explain this topic in your own words without looking.

Real-world: ShopNest Cloud-Native capstone

Eight services, YARP gateway, RabbitMQ, Docker Compose locally, AKS in production, OpenTelemetry traces on every checkout.

Outcome: Portfolio-ready proof you can demo in interviews and on your resume.
