Cassandra C# driver UDT Mapping - Int to Enum

I've got the enum type:

public enum SomeType
{
    Type1,
    Type2,
    Type3
}

and I'd like to map automatically Cassandra int type to the c# enum. I've tried to define it like:

session.UserDefinedTypes.Define(
            UdtMap.For<DefinedType>()
            .Map(a => a.Type, "type"));
// where type of a.Type is SomeType

however it throws the "InvalidTypeException" with message " type type Int32 is not assignable to SomeType"

Is it possible to map it automatically ? I've seen some examples of table column mapping to enumerable, but never any of UDT

Cassandra not yet supported enum type in udt,

Alternatively, you can solve the problem as follows

public enum SomeType
{
Type1=0,
Type2=1,
Type3=2
}

public SomeType SomeTypeProperty;

public int SomeTypePropertyMapForCassandra
{
 get
 {
 return SomeTypePropertyMapForCassandra;
 }
 set
 {
 this.SomeTypeProperty= (SomeType)value;
 }
}
