MapScript C# (MapServer 4.10): mapscriptPINVOKE problem on 64-bit platform.

Thu Jan 25 13:54:05 PST 2007

Ok, I tried to compile using "win64" mode by going through 'Visual Studio 2995
x64 Win64 Command Prompt' but mapserver failed to compile. The error:

Stop.

Probably I need to get past this error first before considering other things.

Thanks.
