Interop.WindowData..GetPositionSize is related to CSharp_Dali_WindowData_GetPositionSize at csharp-binder side:

SWIGEXPORT void* SWIGSTDCALL CSharp_Dali_WindowData_GetPositionSize(void* nuiWindowData)
{
void* nuiResult;
Dali::WindowData* pWindowData;
Dali::Rect result;

pWindowData = (Dali::WindowData*)nuiWindowData;
if(!pWindowData)
{
SWIG_CSharpSetPendingExceptionArgument(SWIG_CSharpArgumentNullException, "Attempt to dereference null Dali::WindowData", 0);
return nullptr;
}

{
try
{
result = pWindowData->GetPositionSize();
}
CALL_CATCH_EXCEPTION(0);
}

nuiResult = new Dali::Rect((const Dali::Rect&)result);
return nuiResult;
}

The return value is allocated by new operator, it need be deleted.

Interop.Picture.GetSize is related to CSharp_Dali_Picture_GetSize:

SWIGEXPORT void *SWIGSTDCALL CSharp_Dali_Picture_GetSize(char *pPicture) {
Dali::CanvasRenderer::Picture picture;
Dali::Vector2 result;

if (!pPicture) {
SWIG_CSharpSetPendingExceptionArgument(
SWIG_CSharpArgumentNullException,
"Attempt to dereference null Dali::CanvasRenderer::Picture", 0);
return nullptr;
}
picture = *(Dali::CanvasRenderer::Picture *)pPicture;

{
try {
result = picture.GetSize();
}
CALL_CATCH_EXCEPTION(0);
}

return new Dali::Vector2((const Dali::Vector2 &)result);
}
