<p><span style="font-size: 10pt; font-family: "Courier New"; color: black;">Ah, finally somebody picked up on that!..</span></p>
<p><span style="font-size: 10pt; font-family: "Courier New"; color: black;">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.</span></p>
<p><span style="font-size: 10pt; font-family: "Courier New"; color: black;"> </span></p>
<p><span style="font-size: 10pt; font-family: "Courier New"; color: black;">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. </span></p>
<p><span style="font-size: 10pt; font-family: "Courier New"; color: black;"> </span></p>
<p><span style="font-size: 10pt; font-family: "Courier New"; color: black;">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..)</span></p>
<p><span style="font-size: 10pt; font-family: "Courier New"; color: black;">From the other side: would the COIN-OR be interested in such a
project being added? </span></p>
<p><span style="font-size: 10pt; font-family: "Courier New"; color: black;">(I'll have a look at the Contributions page)</span></p>
<p><span style="font-size: 10pt; font-family: "Courier New"; color: black;"> </span></p>

<p> </p>
<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>
