Connect Cassandra with .NET Core

[Isuama]

Can we connect Cassandra as the same way we did for MongoDB. I am unable to connect with Cassandra and getting null reference error at ServiceCoordinator.Tell function.
Have I done anything wrong here.

var config = ConfigurationFactory.ParseString(@"
akka.persistence {
journal {
plugin = ""cassandra-journal""
}
cassandra-sessions{
default {
contact-points = [ ""127.0.0.1"" ]
port = 9042
}
}
}");
System = ActorSystem.Create("Service", config);
