How to recognize the frequency of a sound (note) in C#?

Hello!
I want to create an application that takes an audio recording / melody as input and outputs the notes that the program was able to "hear".
How can this idea be realized?
Thanks

Use the Fourier transform to get the spectrum of the record. Then analyze the spectrum for the presence of harmonic notes.
