X509Store is always empty on Linux

Question

I am able to install certificates using the following dotnet tool: https://github.com/gsoft-inc/dotnet-certificate-tool

After installation, I can confirm that the PFX files show up in the '~/.dotnet/corefx/cryptography/x509stores/my' location, as file named in the format, {thumbprint}.pfx.

However, when I try and access the x509 store in the following way:

    var store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
    store.Open(OpenFlags.ReadOnly);
    var certCollection = store.Certificates;

My certCollection is always empty. Any ideas on why this is happening on my Linux machine?
