Late last month just as we were shutting down for the holidays the developer of our C# example, hollow87 updated his proxycheck C# library to support our v2 API including all our latest features such as lat/long and city information.
You can check out the example here on our code examples page or here on the NuGet page for the project. Using this library you can build a very robust implementation of our API in your .net applications with very little effort.
Happy coding! 👩💻
