Datastax c# Cassandra throwing exception after update to 3.X

Question

I've just upgraded the driver from 2.7.3 to 3.0.3 and seems like something weird was done with the Mapper.Single() . It was just working on the old version but now throws an exception;

Exception thrown: 'System.ArgumentException' in Cassandra.dll ("Argument types do not match")

Schema:

CREATE TABLE IF NOT EXISTS client (
    id uuid PRIMARY KEY,
    timezone frozen<timezone>,
    language frozen<language>,
    bank set<frozen<bank>>,
    name text,
    country frozen<country>
);

CREATE TYPE IF NOT EXISTS timezone (
    id uuid,
    name text,
    time int
);

CREATE TYPE IF NOT EXISTS language (
    id uuid,
    name text,
    iso text
);

CREATE TYPE IF NOT EXISTS bank (
    id uuid,
    name text,
    number int
);
CREATE TYPE IF NOT EXISTS country (
    id uuid,
    name text,
    iso2 text,
    iso3 text
);

This code works fast and perfectly on 2.7.X but doesnt work on 3.X.X drivers.

Answer 1

Error was due one of the POCO's got a reference to a frozen type using IList instead IEnumerable.

That used to work on 2.7.X but doesnt work on 3.X.X.

Thanks a lot Jorge!
