Unable to Add certificate to X509Store

Question

Im trying to add a certificate to a certificate store programatically I'm using the following code to fetch a pfx file from a directory and add the certificate to the CurrentUser under My store. The code runs without any exception but I'm not able to see the certificate added in the store. I've tried changing CurrentUser to LocalMachine and have also tried adding under TrustedPeople but with no success.

X509Certificate2 cer = new X509Certificate2(Server.MapPath("<filepath>"), "<pswd>", X509KeyStorageFlags.MachineKeySet );
                StorePermission sp =
            new StorePermission(PermissionState.Unrestricted);
            sp.Flags = StorePermissionFlags.AllFlags;
            sp.Assert();
            X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
            store.Open(OpenFlags.MaxAllowed);
            store.Certificates.Add(cer);
        store.Close();

Answer 1

Have your tried

store.Add(cer);

instead of

store.Certificates.Add(cer);

?
