Thunder Stumpges commented on THRIFT-1127:
------------------------------------------

The point of the default constructor is to initialize member default values. 
However in a case where you have none (or need to have none in order to provide 
your own), I agree that it should not generate one. I am working on a patch 
that will generate the default constructor (as it does today) only if there are 
one or more members that have default values specified. I believe this should 
work for you (it works for me!)

>             Project: Thrift
>          Issue Type: Bug

>    Affects Versions: 0.5

> The C# code generator should not produce a default constructor. 
> Thrift generates partial classes for thrift structs, meaning that the class 
> may be spread across multiple files and csc will link them to be a separate 
> file. When the thrift generated class has the partial constructor, it cannot 
> be added in other files. This is a problem if you want to implement a default 
> constructor that does some initialization to the data in the class.
> For example, this thrift code:
> {code}
> struct DateTime
> {
>     1: required i64 ticks,
> }
> {code}
> produces
> {code}
