Why should you care?

You need Inter-Service Communication in Microservices when moving from one API to many services that deploy independently.

See it live — copy this example

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

// Inter-Service Communication in Microservices
dotnet new webapi -n ShopNest.Service
// Apply this lesson pattern in Program.cs

• Read the example line by line.
• Each part connects to Inter-Service Communication in Microservices.

Try it yourself

1. Create or open the ShopNest service project.
2. Apply the pattern from this lesson.
3. Run dotnet build && dotnet run.
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

You learned Inter-Service Communication in Microservices in plain terms. Practice on ShopNest before moving on.
