¿Cómo puedo enviar Bitcoin de una dirección de Taproot a otra?

Creé una dirección bitcoin principal (bech32m) y envié 1 UTXO desde una dirección segwit que no era taproot (bech32) a esta dirección principal. ¿Cómo escribiría un script de c# para enviar este btc a otra dirección principal? No necesito nada demasiado complicado, solo un script simple para enviar este btc de una dirección principal a otra. Creo que Bitcoin sería el paquete más sensato de usar.

Encontré esto en una de las pruebas de NBitcoin:

Pero no puedo entender cómo escribir una aplicación de consola C# simple en el formato:

class Program
{
    static async Task Main()
    ...

}

Tengo la clave privada, así como la frase mnemotécnica completa para la clave privada, de la dirección bitcoin principal (bech32m) que financié con 1 UTXO. ¿Cómo escribiría una sencilla aplicación de consola de C# que transfiera este código utxo a otra dirección principal?
