<div>Hi Tamas,</div>
<div> </div>
<div>thank you for your professional info. I will take a deep look into the things you mentioned. Maybe I will bother you again for more information. </div>

<br>The C# mapscript interface is known stable, and uses the .NET platform<br>invoke mechanism for the communication between the C and the C# parts<br>(mapscript.dll and mapscript_csharp.dll on windows for example). You<br>
can use the object model of the C# interface (contained in the<br>mapscript_csharp.dll assembly) to achieve the required functionality<br>for your .NET application.<br><br>When using the mapscript C# API you have to take care of the threading
<br>model of the host<br>process invoking the API. You have to compile mapserver with thread<br>support and avoid using the thread unsafe libraries. For more details:<br><a href="http://mapserver.gis.umn.edu/docs/faq/thread_safety">

2.0 you must compile the code with Visual Studio<br>2005. For the C# specific compilation issues visit:<br><a href="http://mapserver.gis.umn.edu/docs/howto/mapscriptcscompile">http://mapserver.gis.umn.edu/docs/howto/mapscriptcscompile
