I am trying to programmatically import a X509 certificate (pfx / PKCS#12) in my local machine's certificate store. This particular certificate has a chain of certificates, the certification path looks something like this:

  • Root certificate CA
    • Organization certificate CA
      • Organization 2 certificate CA
        • My certificate

The code I use looks like this:

cert = new X509Certificate2(pathToCert, password);

if (cert != null)
{
    var store = new X509Store(StoreName.My, StoreLocation.LocalMachine);
    store.Open(OpenFlags.ReadWrite);
    if (!store.Certificates.Contains(cert))
    {
        store.Add(cert);
    }
}

This code does import the certificate, however it seems to ignore the chain. If I check the certificate in the store, the certification path only shows:

  • My certificate

However when I import the pfx manually, it does show the full path. Am I skipping a step here, or am I missing some parameter? Can someone shed some light on this?

c# pfx x509certificate2 pkcs#12
