Configure RabbitMQ Connection

RabbitMQ connectivity starts with a connection factory.

The connection is typically shared across multiple publishers and subscribers.

---

RabbitMQ.Client v6

var factory = new ConnectionFactory
{
    HostName = "localhost",
    UserName = "guest",
    Password = "guest"
};

using var connection =
    factory.CreateConnection();

---

RabbitMQ.Client v7

var factory = new ConnectionFactory
{
    HostName = "localhost",
    UserName = "guest",
    Password = "guest"
};

await using var connection =
    await factory.CreateConnectionAsync();

Recommended:

• one connection per application;
• multiple channels per connection.

Avoid creating connections per message.

Production Considerations

Typical production settings include:

• TLS encryption;
• heartbeat configuration;
• automatic recovery;
• connection monitoring.

These settings are transport-specific and should follow RabbitMQ best practices.
