thank you for trying to share your work.<br>
<br>
another approach could be to have coin solvers as plugins in new Microsoft
Solver Foundation.<br>

few years ago we (I..) started to develop a .NET wrapper, not unlike flopc++ or

<p>Hi All,<br>
<br>
I would like to use OSI in c# to Solve some MIP problems.<br>
<br>
I found some old post in the list :<br>
<a href="http://list.coin-or.org/pipermail/coin-discuss/2006-March/001897.html"
target="_blank">http://list.coin-or.org/pipermail/coin-discuss/2006-March/001897.html</a><br>
<br>
and was wandering if now there would be a .net interface for OSI I could use ?
or some sample code ?<br>
<br>
Best Regards,<br>
Thierry<br>
