The Twilio next-generation C# helper library is now available, offering improved productivity with its novel approach to making the libraries more consistent, enabling faster iteration, and improving the libraries by having a shared foundation across languages. The new library features full cross-platform .NET Core support, async/await, automatic paging when requesting a list of resources, and addition of helper classes to generate TwiML. It is compatible with all the way back to .NET Framework version 3.5 and targets .NET Standard, allowing it to be used with cross-platform .NET Core applications. The new library also includes asynchronous methods for creating, fetching, reading, updating, and deleting resources, as well as helper classes to generate TwiML for voice and messaging responses.
