I'm happy to announce the release of NBitcoin v1.0.4.1, which include the payment protocol (BIP 70, 21, 72).
How to use can be found in the tests here : https://github.com/NicolasDorier/NBitcoin/blob/master/NBitcoin.Tests/PaymentTests.cs
Example
{
using(var server = new PaymentServerTester())
{
var uri = server.GetPaymentRequestUri(2);
BitcoinUrlBuilder btcUri = new BitcoinUrlBuilder(uri);
var request = btcUri.GetPaymentRequest();
Assert.True(request.VerifySignature());
Assert.Equal(2, BitConverter.ToInt32(request.Details.MerchantData, 0));
var ack = request.CreatePayment().SubmitPayment();
Assert.NotNull(ack);
}
}
Have fun !
