[Insight-users] Crashes with native ITK in Managed C++

[Dan Mueller]

Hi Young,

This is problem discussed in:
   http://www.itk.org/pipermail/insight-users/2006-October/019652.html

For some reason (which I can not figure) you must separate your ITK
code from your GUI code using separate libraries (it seems that
Windows Forms executables like to be built with /clr:pure, not mixed
mode with ITK).

HTH

Cheers, Dan
