_From @eerhardt on March 26th_ from ` - internal const string NativePath = @"Microsoft.MachineLearning.CpuMathNative.dll"; ` to `+ internal const string NativePath = "CpuMathNative"; ` Glad this worked, and thanks for filing the CoreCLR issue. As far as I can tell this should work on netcoreapp2.0 and desktop as well, but we should test that since this codepath has undergone a few changes in 2.1. Also we may consider adding something more specific to the name since we won't be able to rely on a fix for dotnet/coreclr#17150.
