Jose.JWT.Encode gives Invalid algorithm specified Exception

Question

I have Using .Net45 framework I want the token from the certificate file.

var privateKey=new X509Certificate2("my-key.p12", "password", X509KeyStorageFlags.Exportable | X509KeyStorageFlags.MachineKeySet).PrivateKey as RSACryptoServiceProvider;
string token=Jose.JWT.Encode(payload, privateKey, JwsAlgorithm.RS256);

The above code gives Invalid algorithm Exception..

But the same time when i move to net4.6 it works good with the following code.

var privateKey=new X509Certificate2("my-key.p12", "password").GetRSAPrivateKey();
string token=Jose.JWT.Encode(payload, privateKey, JwsAlgorithm.RS256);

Could you please give any suggestion for this issue ?
