This application uses ASP.NET Core 3.1 as its backend framework, Angular 9 as the frontend framework, and Twilio Programmable Video for video chat functionality. It is deployed to Microsoft Azure's App Service platform, providing a robust, enterprise-class web hosting environment with continuous deployment capabilities through Visual Studio. The process involves publishing the application to Azure, configuring it with Twilio user secrets, and testing its video chat functionality. With this setup, developers can leverage Azure's scalable infrastructure and Visual Studio's development tools to build and deploy their own video chat applications.
