Port Out Validation Implementation Example in C#

This document provides a walkthrough of implementing a sample solution using Bandwidth's Port Out Validation. It includes a ValuesController.cs file that receives webhooks from Bandwidth and validates the data against stored values. The code assumes familiarity with C#, .NET Core, and ASP.NET Core. The provided sample is not a fully implemented port out validation solution but serves as an example of the general process involved in such a solution. It includes functions for checking numbers, account IDs, and PINs against stored data, generating validation failure XML with error descriptions, and generating validation success XML. The code also defines routes that receive webhooks and processes the incoming data to determine whether it passes or fails validation.
