[Osi] C# interface to OSI

[Goossens Jan-Willem]

Thierry,

Ah, finally somebody picked up on that!..
Yes, a few years ago we (I..) started to develop a .NET wrapper, not unlike flopc++ or CONCERT (but not as advanced), with classes like Model, Variable, Constraint and (linear) Expression, and many overloaded operators (like "+", "<=" etc). The wrapper is written in C++/CLI (aka C++ with Managed extension) in Visual Studio 2005, and simply links in the LIBs of CBC, CGL, CLP and their OSIs, to form one mixed-mode .NET DLL.

Setting all this up was not too difficult, and we've been using this a lot ever since. This final product has, until now, never left closed-source-ness, partly also because nobody was asking for it.

Maybe this is a good point to try to get my bosses to agree to give back and contribute our code to the COIN community (but probably don't hold your breath..)
>From the other side: would the COIN-OR be interested in such a project being added?
(I'll have a look at the Contributions page)

Regards,

Jan-Willem

Subject: [Osi] C# interface to OSI

Hi All,

I would like to use OSI in c# to Solve some MIP problems.

I found some old post in the list :
http://list.coin-or.org/pipermail/coin-discuss/2006-March/001897.html

and was wandering if now there would be a .net interface for OSI I could use ? or some sample code ?

Best Regards,
Thierry
