Now, I'm prepared to make the change, but in the true spirit of _REAL_
amateur radio to do everything myself.

My question is, what sound card drivers are used for the PC end of the
various softrock, SDRs, etc?

Is it via a .NET component, or perhaps the age-old DirectX approach?

Found this which is quite good, it covers all USB and so a lot of the
endpoint data is irrelevant but for an SDR it should be a simple case of
claiming the interface (there should be one possibly two) and opening up
a pipe to the endpoint to hoover up the data.
I am guessing that on an SDR there will be one standard 'out' endpoint
and probably a single input control interface.

What language are you planning to write it in?
