Numerical Analysis tools for C#?

Hi everyone, I'm doing some machine learning stuff and wanted to play around a bit with some online applications. I'm doing a great deal of C# programming with ASP.NET. I thought about learning Python and then using IronPython to implement it in the .NET framework, but I don't think NumPy and SciPy are implemented yet. Plus I don't know Python as well as I do C#. Are there any good resources for just coding these advanced math techniques in C# directly?
