QUESTION
I want to use FFTW.NET in .NET Core 2.1 WEB API. When I execute below piece of code in action, I get System.InvalidOperationException: 'IsAvailable returns false.'
at DFT.FFT(pinIn, pinOut);

is called internally to test whether the interop layer is happy - found here.
It looks like it'll return false
if trying to load the Dll resulted in a DllNotFoundException
(via the GetVersionAndInitialize
and _version
).
So the native DLLs aren't in the right place to be loaded. If it's not clear which locations are being probed for the DLLs you might want to use Process Monitor to look for the failed probing attempts to load the DLLs.
