Chat Application With ASP.NET MVC Using RabbitMQ<\/p>\n\n\n\n

In this article, you will learn how to develop a chat application in ASP.NET MVC using RabbitMQ. First, you need to download RabbitMQ and OTP.<\/p>\n\n\n\n

Step 1: RabbitMQ<\/strong>

<\/a>https:\/\/www.rabbitmq.com\/download.html<\/em>
 <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 2: OTP<\/strong>

http:\/\/www.erlang.org\/downloads<\/em><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Create a new MVC project.

Step 3: Open Visual Studio<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Go to File menu and select New Project->Web application->MVC.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

From New Project, select ASP.NET Web Application and click OK.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Select MVC and click OK.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

In Visual Studio, the folder structure is shown as below in the Solution Explorer for the chat application.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Right-click on Project and select “Manage NuGet Packages..”.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Search Rabbitmq and install the rabbitmq.client<\/em> package.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Adding new HomeController<\/strong>

Right-click on Controllers folder, click Add >> Controller.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Once the user selects the controller, the “Add Scaffold” dialog gets opened. Select MVC 5 Controller \u2013 Empty and click “Add” button.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Give Controller a name (HomeController) and click “Add”.

<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n



Once the user clicks on Add button, the Workspace will be opened to write the code.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Paste the below code in HomeController.<\/p>\n\n\n\n
