问题
I'm using the Wolfram Alpha API wrapper for .NET at this location
http://products.wolframalpha.com/api/libraries.html
However it's written in VB.NET and written for version 1.0 of the API. It's unusable.
Does anyone know of a better API wrapper?
回答1:
Here is code that will work with the new API; I got it from Azure Dallas
