3.1. Prerequisites

  • You must complete the installation procedure for your environment.
  • You must have an AMQP 1.0 message broker listening for connections on interface localhost and port 5672. It must have anonymous access enabled. For more information, see Starting the broker.
  • You must have a queue named hello-world-example. For more information, see Creating a queue.
  • Alternatively, you can specify above information using following environment variables: HOST, PORT, ADDRESS
  • The examples are available from the source or upstream
  • Download the amq-qpid-proton-dotnet-1.0.0-M9-src .zip file. When you extract the contents of the .zip file, a directory named amq-dotnet-1.0.0-M9-src is created. This is the top-level directory of the installation and is referred to as <src-install-dir> throughout this document.

The Hello World example creates a connection to the broker, sends a message containing a greeting to the hello-world-example queue, and receives it back. On success, it prints the received message to the console.

Change to the <source-dir>/examples/Example.HelloWorld/ and use dotnet run to build and execute the program. 

$ cd <source-dir>/examples/Example.HelloWorld/
$ dotnet run
Received message with body: Hello World
