NServiceBus C# (How It Works For Developers)
NServiceBus is a powerful and adaptable service bus designed for the .NET Framework that streamlines distributed system development. The strong messaging patterns it offers guarantee dependable message handling and delivery across several microservices and applications. NServiceBus abstracts the underlying messaging architecture, allowing developers to concentrate on business logic instead of the intricacies of building distributed systems.
In contrast, IronPDF is a well-liked .NET library for generating, viewing, and modifying PDF files. It is well-known for being easy to use and very efficient at creating PDFs from various sources, such as ASPX files and HTML.
Developers may build dependable, scalable, and maintainable software systems that can generate and manage PDF documents as part of their business operations by combining NServiceBus and IronPDF.
We will look at how to set up a simple C# NServiceBus project and integrate it with IronPDF in this article, so you can build a streamlined workflow for managing and producing PDF documents in a distributed application architecture. After reading this introduction tutorial, you ought to know exactly how these two effective technologies can cooperate to simplify your PDF-related tasks in a distributed setting.
What is NServiceBus C#?
NServiceBus is a powerful and adaptable framework that makes it easy to create distributed systems and service-oriented .NET architectures. By utilizing NServiceBus, you can easily manage various message types and ensure reliable communication. This is crucial, particularly in a web application and similar architectures where seamless message routing and processing are essential. NServiceBus's message handlers effectively deal with receiving messages, ensuring that every logical component interacts smoothly. NServiceBus has the following important features:
Features of NServiceBus
Message-Based Communication
NServiceBus encourages message-based communication between different services or components in a system. By decoupling components, this method creates designs that are easier to scale and manage.
Reliable Messaging
By automatically managing retries, dead-letter queues, and other fault tolerance techniques, it guarantees dependable message delivery. In distributed systems, where network outages and other problems of failure are frequent, this dependability is essential.
Publish/Subscribe Model
The publish/subscribe pattern is supported by NServiceBus, enabling services to publish events and let other services subscribe to these events. This makes event-driven architectures possible, in which modifications made to events in one component of the system can cause responses in other components.
Saga Management
Long-running business processes may be managed with NServiceBus thanks to its integrated support for sagas. Sagas make it possible for the service platform to manage state and coordinate intricate operations among several services.
Extensibility and Customization
It offers an exceptional level of extensibility, enabling developers to personalize the handling, processing, and transportation process of messages. Because of its adaptability, it can be used in a variety of scenarios.
Integration with Various Messaging Platforms
Numerous messaging systems, including MSMQ, RabbitMQ, Azure Service Bus, Amazon SQS, and others, can be integrated with NServiceBus. This enables developers to select the communications infrastructure solution that best suits their requirements.
Create and configure NServiceBus in C#
You must first set up your development environment, create a basic project, and build a basic messaging service and scenario before you can begin using NServiceBus in a C# project. Here's a step-by-step guide to get you going.

Install-Package IronPdf
Configure the Sender With Message
Messages is a shared project (class library) that the sender and the recipient will both use. Define the message class in the Messages project. Create a new Class Library project called Messages and add it to the solution.
Define the Message:
Inside the Messages project, create a new class called GeneratePdfMessage.cs
:
using NServiceBus;
public class GeneratePdfMessage : IMessage
{
public string Content { get; set; }
public string OutputPath { get; set; }
}
using NServiceBus;
public class GeneratePdfMessage : IMessage
{
public string Content { get; set; }
public string OutputPath { get; set; }
}
Imports NServiceBus
Public Class GeneratePdfMessage
Implements IMessage
Public Property Content() As String
Public Property OutputPath() As String
End Class
In both the Sender and Receiver projects, include a reference to the Messages project.
Set up the NServiceBus endpoint in the Sender project to use RabbitMQ for message delivery.
using NServiceBus;
using System;
using System.Threading.Tasks;
using Messages;
class Program
{
static async Task Main()
{
Console.Title = "Sender";
var endpointConfiguration = new EndpointConfiguration("SenderEndpoint");
// Use RabbitMQ Transport
var transport = endpointConfiguration.UseTransport<RabbitMQTransport>();
transport.ConnectionString("host=localhost");
// Set up error queue
endpointConfiguration.SendFailedMessagesTo("error");
// Set up audit queue
endpointConfiguration.AuditProcessedMessagesTo("audit");
endpointConfiguration.EnableInstallers();
// Start the endpoint
var endpointInstance = await Endpoint.Start(endpointConfiguration).ConfigureAwait(false);
Console.WriteLine("Press Enter to send a message...");
Console.ReadLine();
// Send a message
var message = new GeneratePdfMessage
{
Content = "<h1>Hello, NServiceBus with RabbitMQ and IronPDF!</h1>",
OutputPath = "output.pdf"
};
await endpointInstance.Send("ReceiverEndpoint", message).ConfigureAwait(false);
Console.WriteLine("Message sent. Press Enter to exit...");
Console.ReadLine();
// Stop the endpoint
await endpointInstance.Stop().ConfigureAwait(false);
}
}
using NServiceBus;
using System;
using System.Threading.Tasks;
using Messages;
class Program
{
static async Task Main()
{
Console.Title = "Sender";
var endpointConfiguration = new EndpointConfiguration("SenderEndpoint");
// Use RabbitMQ Transport
var transport = endpointConfiguration.UseTransport<RabbitMQTransport>();
transport.ConnectionString("host=localhost");
// Set up error queue
endpointConfiguration.SendFailedMessagesTo("error");
// Set up audit queue
endpointConfiguration.AuditProcessedMessagesTo("audit");
endpointConfiguration.EnableInstallers();
// Start the endpoint
var endpointInstance = await Endpoint.Start(endpointConfiguration).ConfigureAwait(false);
Console.WriteLine("Press Enter to send a message...");
Console.ReadLine();
// Send a message
var message = new GeneratePdfMessage
{
Content = "<h1>Hello, NServiceBus with RabbitMQ and IronPDF!</h1>",
OutputPath = "output.pdf"
};
await endpointInstance.Send("ReceiverEndpoint", message).ConfigureAwait(false);
Console.WriteLine("Message sent. Press Enter to exit...");
Console.ReadLine();
// Stop the endpoint
await endpointInstance.Stop().ConfigureAwait(false);
}
}

Await endpointInstance.Send("ReceiverEndpoint", message).ConfigureAwait(False)
Console.WriteLine("Message sent. Press Enter to exit...")
Console.ReadLine()
' Stop the endpoint
Await endpointInstance.Stop().ConfigureAwait(False)
End Function
End Class
Endpoint Configuration: the endpoint is initialized with the name "SenderEndpoint" by calling new EndpointConfiguration("SenderEndpoint").
endpointConfiguration is the transport configuration. By connecting to a local RabbitMQ instance, the method UseTransport() sets up NServiceBus to use RabbitMQ as the transport mechanism.
Audit and Error Queues Where to send failed messages and audit processed messages is configured using SendFailedMessagesTo("error")
and AuditProcessedMessagesTo("audit")
, respectively.
Message Sent: endpointInstance.Send("ReceiverEndpoint", message)
sends a GeneratePdfMessage to the "ReceiverEndpoint".
Configure the Receiver to Generate PDF
Set up the NServiceBus endpoint in the Receiver project to accept messages over RabbitMQ and produce PDFs using IronPDF.
using NServiceBus;
using System;
using System.Threading.Tasks;
class Program
{
static async Task Main()
{
Console.Title = "Receiver";
var endpointConfiguration = new EndpointConfiguration("ReceiverEndpoint");
// Use RabbitMQ Transport
var transport = endpointConfiguration.UseTransport<RabbitMQTransport>();
transport.ConnectionString("host=localhost");
// Set up error queue
endpointConfiguration.SendFailedMessagesTo("error");
// Set up audit queue
endpointConfiguration.AuditProcessedMessagesTo("audit");
// Start the endpoint
var endpointInstance = await Endpoint.Start(endpointConfiguration).ConfigureAwait(false);
Console.WriteLine("Press Enter to exit...");
Console.ReadLine();
// Stop the endpoint
await endpointInstance.Stop().ConfigureAwait(false);
}
}
using NServiceBus;
using System;
using System.Threading.Tasks;
class Program
{
static async Task Main()
{
Console.Title = "Receiver";
var endpointConfiguration = new EndpointConfiguration("ReceiverEndpoint");
// Use RabbitMQ Transport
var transport = endpointConfiguration.UseTransport<RabbitMQTransport>();
transport.ConnectionString("host=localhost");
// Set up error queue
endpointConfiguration.SendFailedMessagesTo("error");
// Set up audit queue
endpointConfiguration.AuditProcessedMessagesTo("audit");
// Start the endpoint
var endpointInstance = await Endpoint.Start(endpointConfiguration).ConfigureAwait(false);
Console.WriteLine("Press Enter to exit...");
Console.ReadLine();
// Stop the endpoint
await endpointInstance.Stop().ConfigureAwait(false);
}
}
Imports NServiceBus
Imports System
Imports System.Threading.Tasks
Friend Class Program
Shared Async Function Main() As Task
Console.Title = "Receiver"
Dim endpointConfiguration As New EndpointConfiguration("ReceiverEndpoint")
' Use RabbitMQ Transport
Dim transport = endpointConfiguration.UseTransport(Of RabbitMQTransport)()
transport.ConnectionString("host=localhost")
' Set up error queue
endpointConfiguration.SendFailedMessagesTo("error")
' Set up audit queue
endpointConfiguration.AuditProcessedMessagesTo("audit")
' Start the endpoint
Dim endpointInstance = Await Endpoint.Start(endpointConfiguration).ConfigureAwait(False)
Console.WriteLine("Press Enter to exit...")
Console.ReadLine()
' Stop the endpoint
Await endpointInstance.Stop().ConfigureAwait(False)
End Function
End Class
This setup, for the "ReceiverEndpoint" receiver endpoint, is comparable to the Sender configuration.
Message Handler
In the Receiver project, create a new class called GeneratePdfMessageHandler.cs
.
using NServiceBus;
using System;
using System.Threading.Tasks;
using Messages;
using IronPdf;
public class GeneratePdfMessageHandler : IHandleMessages<GeneratePdfMessage>
{
public Task Handle(GeneratePdfMessage message, IMessageHandlerContext context)
{
Console.WriteLine($"Received message to generate PDF with content: {message.Content}");
// Generate PDF
var renderer = new HtmlToPdf();
var pdf = renderer.RenderHtmlAsPdf(message.Content);
pdf.SaveAs(message.OutputPath);
Console.WriteLine($"PDF generated and saved to: {message.OutputPath}");
return Task.CompletedTask;
}
}
using NServiceBus;
using System;
using System.Threading.Tasks;
using Messages;
using IronPdf;
public class GeneratePdfMessageHandler : IHandleMessages<GeneratePdfMessage>
{
public Task Handle(GeneratePdfMessage message, IMessageHandlerContext context)
{
Console.WriteLine($"Received message to generate PDF with content: {message.Content}");
// Generate PDF
var renderer = new HtmlToPdf();
var pdf = renderer.RenderHtmlAsPdf(message.Content);
pdf.SaveAs(message.OutputPath);
Console.WriteLine($"PDF generated and saved to: {message.OutputPath}");
return Task.CompletedTask;
}
}
Imports NServiceBus
Imports System
Imports System.Threading.Tasks
Imports Messages
Imports IronPdf
Public Class GeneratePdfMessageHandler
Implements IHandleMessages(Of GeneratePdfMessage)
Public Function Handle(ByVal message As GeneratePdfMessage, ByVal context As IMessageHandlerContext) As Task
Console.WriteLine($"Received message to generate PDF with content: {message.Content}")
' Generate PDF
Dim renderer = New HtmlToPdf()
Dim pdf = renderer.RenderHtmlAsPdf(message.Content)
pdf.SaveAs(message.OutputPath)
Console.WriteLine($"PDF generated and saved to: {message.OutputPath}")
Return Task.CompletedTask
End Function
End Class
GeneratePdfMessageHandler
uses the IHandleMessages
interface to handle messages of type GeneratePdfMessage
.
Handle Method: After receiving the message, the Handle
function creates a PDF using IronPDF. The HTML content in the message is converted into a PDF by the HtmlToPdf
renderer code, which then saves it to the designated output path.
Conclusion
