A small library written in C# using the .NET 4 framework which provides easy access to the Wolfram Alpha (http://www.wolframalpha.com) API through any .NET language (as it's CLS-compliant).
C#
Wolfram API
This library provides:
An easy way of solving mathematical operations.
An easy way of requesting informations about specific words, topics, etc. (WIP)
Well documented and clean source code.
CLS-compliancy
In order to use, you need:
An application identifier (AppID) from Wolfram. You can get one for free, you just have to register your application.
.NET Framework 4.0
A very simple example
var client = new WAClient("XXXXXX-XXXXXXXXXX"); // replace that with your AppID.
var solution = client.Solve("33^4 + sqrt(12^2 + 13^2)"); // replace with any mathematical operation
// 'solution' now contains the solution by Wolfram Alpha.
// report bugs! :)
