Konstantin updated THRIFT-5040:
-------------------------------
Description:
Optional fields for value types are not Nullable in C# (netstd)
for example
{code:java}
struct Test {
1: required i64 id,
2: optional bool some_flag
}
{code}
will generate class
{code:java}
public partial class Test : TBase{
private bool _some_flag;
public long Id { get; set; }
public bool Some_flag { get { return _some_flag; } set {
__isset.some_flag = true; this._some_flag = value; } }
{code}
that makes the some_flag to be false even if it was not set on the sending
party.
The optional value types should be generated as Nullable<T>:
{code:java}
private bool? _some_flag;
{code}
This is especially harmful with other value types
