Create a Fraud Detection Microservice in .NET and Vonage

The Vonage Number Insights API can help companies verify if a phone number provided by a prospective client is real and active, which is valuable for services like insurance policies or mobile phone plans. A .NET microservice using the Vonage C# SDK client and Coravel can be built to accept messages from a message queue, process them by calling the Vonage API, and send a response back to the queue. The microservice simulates interacting with inputs and outputs via an event bus or queue, storing messages/events in the file system for simplicity. It uses a mock distributed messaging system to test and demonstrate its functionality, allowing each service to be autonomous and resilient.
