Remarks

NumSharp.Core is 100 % managed C# and ships no matrix factorisation of its own — unlike the matrix products, which always have a managed kernel to fall back to. The factorisations (inv, det, solve, svd, eig, qr, …) are served by an IBlasBackend assigned to NumSharp.Backends.TensorEngine.Blas, and the package that supplies one is PackageId. There is no separate seam to install: the one NumSharp.Interop.OpenBLAS reference fills the whole Blas property — products and factorisations alike — from a [ModuleInitializer], so adding the reference is the whole opt-in.

Distinct from the interop package's own OpenBlasRequiredOverrideException: that is thrown when the package IS referenced but a hard-required build override cannot load. This one is thrown by Core when no backend is referenced at all.
