A Hands-On Guide to Azure Cosmos DB in .NET API

Greetings, fellow coders! Get ready to embark on a coding odyssey as we delve into the cosmos with Azure Cosmos DB in .NET API. To make this journey even more exciting, let’s tackle a real-world business problem along the way. So, fasten your seatbelts and prepare for some cosmic coding!

Chapter 1: The Celestial Catalog Business Problem

Imagine you’re tasked with building a Space Explorer app where astronomers can log their celestial discoveries. Each discovery, or “CelestialObject,” has properties like Name, Type, and DiscoveryDate. The goal is to create an API that allows astronomers to add new discoveries, retrieve them, and perform advanced queries.

Chapter 2: Setting Up the Spaceship

// Install the Azure Cosmos DB SDK
dotnet add package Microsoft.Azure.Cosmos

Chapter 3: Connecting to the Cosmic Database

// In your API initialization code
string endpointUri = "your-cosmosdb-endpoint-uri";
string primaryKey = "your-cosmosdb-primary-key";

CosmosClient cosmosClient = new CosmosClient(endpointUri, primaryKey);
