Default Serialiser Settings Helper

[StuartFerguson]

Ignore base domain event properties so they are not written to Event Store

var options = new JsonSerializerOptions
{
    TypeInfoResolver = new DefaultJsonTypeInfoResolver
    {
        Modifiers =
        {
            typeInfo =>
            {
                if (typeInfo.Type == typeof(MyDto))
                {
                    var prop = typeInfo.Properties
                        .FirstOrDefault(p => p.Name == "AggregateId");

                    if (prop != null)
                        prop.ShouldSerialize = (_, _) => false;
                }
            }
        }
    }
};

Property Names are

• AggregateId
• AggregateVersion
• EventId
• EventNumber
• EventTimestamp
• EventType

Json Input and Output formatting

var options = new JsonSerializerOptions
{
    PropertyNamingPolicy = new SnakeCaseNamingPolicy()
};

This only covers System.Text.Json at the moment
