MongoDB with ASP.NET Core: Best Practices

Configure MongoClient in ASP.NET Core

Create a new ASP.NET Core project and register MongoClient as a singleton using a connection string from configuration.

Expected output: MongoClient is registered and injectable in services.

Hint: Use the AddSingleton method in the ConfigureServices method and retrieve the connection string from appsettings.json.

Design a MongoDB Document Schema

Design a C# class representing a blog post with embedded comments suitable for MongoDB storage.

Expected output: A C# class with appropriate properties representing the document.

Hint: Use lists to embed comments and include fields like Title, Content, Author, and Comments.

Implement Error Handling for MongoDB Operations

Write a method that performs a MongoDB query and handles potential connection exceptions gracefully.

Expected output: Method handles exceptions without crashing and logs errors.

Hint: Use try-catch blocks and log exceptions using ASP.NET Core logging.

MongoClient manages connection pooling internally, so registering it as a singleton allows reuse of connections, improving performance and resource management.

Embedding stores related data together for faster reads when accessed together, while referencing avoids duplication and is better for large or frequently changing related data.

By catching exceptions like MongoConnectionException, implementing retry logic if appropriate, and logging errors for diagnostics.
