Azure Active Directory B2C and Azure Functions

Asynchronous Programming in .NET 4.5 – in Spanish

Hello everyone, My colleague José Ortega and I just published some articles about the new .NET 4.5 keywords await and async, and about the Task Parallel Library (TPL).

Be careful when making DataTransferManager.DataRequested an async function
