ASP.NET and mapscript - unable to load DLL

[Mike Boos]

Hello

I'm trying to run Mapscript using the SWIG C# bindings on an ASP.NET 
server. I compiled the 4.6.0 version of MapServer and have placed what I 
believe to be the appropriate dependencies (mapscript_csharp.dll, 
mapscript.dll, libmap.dll, bgd.dll, gdal12.dll, pdflib.dll) in the bin 
directory on my server. It is appears to be finding 
mapscript_csharp.dll, but is having trouble finding mapscript.dll or one 
of its dependencies. I am seeing the following error message:


  Server Error in '/' Application.


    /Unable to load DLL (mapscript)./

* Description: *An unhandled exception occurred during the execution of 
the current web request. Please review the stack trace for more 
information about the error and where it originated in the code.

* Exception Details: *System.DllNotFoundException: Unable to load DLL 
(mapscript).

Am I missing a dependency? Or do I need to set some configuration option 
or place the files elsewhere?

Thanks!
