How can I convert polyline to polycurve

[PradeepS]

Hi , I am new to arcgis. We are developing an applicatin using WPF, its an offline application . I want to convert polylines to polycuve. I am using runtime : 10.2.7. I want to draw a smooth polylines. I found a link having  IPolycurve.Smooth, but I didnt find this function in 10.2.7.  Please suggest. I am providing link for reference. 

IPolycurve.Smooth Method 

Thanks,

Curves aren't yet supported by the runtime. The best way to create a smooth curve currently is using more vertices.

Thank you Nielsen.

Do you have an idea when the runtime will support curves? We have an offline application as well (runtime 100.0), and we've written our own geometry engine to work with curves. We have to densify them every time they're drawn, which takes a substantial amount of time, depending on the curve's radius.
