FFT or DFT library for C#

[C# Programming]

I need a DFT library for C#. I tried this http://www.exocortex.org/dsp (http://www.exocortex.org/dsp/)[^ (http://www.exocortex.org/dsp/)]
But it did not work the way I wanted to.


Do you know of any other librarys in C# that is available either free of cost or for money?

Thanks
