>             Project: Thrift
>          Issue Type: Wish
>          Components: netstd - Compiler
>    Affects Versions: 0.13.0
>            Reporter: Konstantin
>            Priority: Major

> 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 like int, enums, etc...
