PushSharp throwing CryptographicException: Certificate instance is empty

I can't get PushSharp to work, I'm pretty sure the problem is something I'm doing incorrectly, though I have no idea what... :/

Here's the code:

var cert = new X509Certificate2(
                "cio_aps_development.p12",
                "",
                X509KeyStorageFlags.MachineKeySet |
                X509KeyStorageFlags.PersistKeySet |
                X509KeyStorageFlags.Exportable);

//var config = new ApnsConfiguration(ApnsConfiguration.ApnsServerEnvironment.Sandbox, "cio_aps_development.p12", "");
var config = new ApnsConfiguration(ApnsConfiguration.ApnsServerEnvironment.Sandbox, cert);

It doesn't matter which approach I take, I get this error:

System.Security.Cryptography.CryptographicException: Certificate instance is empty.

System.Security.Cryptography.CryptographicException: Certificate instance is empty.

Any ideas?

Thanks!

Solution

  • For future reference:

    The problem was my p12 file. It hadn't been properly exported. After exporting it the right way, it worked.
