I have created a separate directory – set in PATH variable – where I have overwritten all dll’s from the downloaded package, but I actually forgot to substitute mapscript.dll and mapscript_csharp.dll. Tried again and … I have some good news:
Tried <http://www.gisinternals.com/sdk/PackageList.aspx?file=release-1600-gdal-1-8-mapserver-6-0.zip> release-1600-gdal-1-8-mapserver-6-0 à Did not even compile: it complains the .NET version is newer (I’m using .NET 3.5, not 4.0)
Tried <http://www.gisinternals.com/sdk/PackageList.aspx?file=release-1600-gdal-mapserver.zip> release-1600-gdal-mapserver à Did not even compile: it complains the .NET version is newer (I’m using .NET 3.5, not 4.0)

So, in my environment I have to use binaries compiled with VS2008, unless I decide to upgrade to .NET 4.0.
Thanks a lot Tamas, I’m on track now!

Did you deploy all the dll-s can be found in the same package? Mixing the dll-s from different packages (distribution sources) may lead to memory corruption issues.

Tried with MSVC2010 (Win32), got this exception:

How did you obtain the binaries? I'd be curious to know whether the binaries from http://www.gisinternals.com/sdk/ would work or not?
You might want to try using the MSVC2010 versions x86 or x64 depending on your OS platform/architecture.

Yes, I think this is a permission issue, as most of IIS related problems ...
I also made another try:
I ported the previous code to a simple, simple console application. Well,
while the ASP.NET version fails both with IIS and with the VS2010 web
debugger, the console program works smoothly, producing all 10 image maps
and even filling the MS_ERRORFILE file with lots of stuff. Tried also with a
remote Windows 2008 Server, even there the web version does not work.
Here is the code:
///BEGIN
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using OSGeo.MapServer;
using System.IO;
namespace GenerateMap
{
class Program
{
const string MERCATORE_PROJ4 = "+proj=merc +a=6378137 +b=6378137
+lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null
+wktext +no_defs";
const string WGS84_PROJ4 = "+proj=longlat +ellps=WGS84 +datum=WGS84
+no_defs";
static void DrawAMap(int index)
{
bool exists;
string filename =
@"C:\usr\lavoro\progetti\SilverlightMapServer\GisData\Demo\Terni\terni.map";
mapObj map = null;
try
{
map = new mapObj(filename);
}
catch (Exception ex)
{
string msg = ex.Message;
Console.WriteLine(msg);
}
int w = 800;
map.width = w;
int h = 600;
map.height = h;
rectObj bbox = new rectObj(12.6198865008904, 42.5498576637217,
12.6710248924462, 42.5784118606357, 0);
map.setProjection(MERCATORE_PROJ4);
projectionObj projMercatore = new
projectionObj(MERCATORE_PROJ4);
projectionObj projWGS84 = new projectionObj(WGS84_PROJ4);
try
{
///HERE first time OK, second time hangs
bbox.project(projWGS84, projMercatore);
}
catch (Exception ex)
{
string msg = ex.Message;
Console.WriteLine(msg);
}
//map.extent = bbox;
map.setExtent(bbox.minx, bbox.miny, bbox.maxx, bbox.maxy);
imageObj image = map.draw();
MemoryStream memstrm = new MemoryStream(image.getBytes());
memstrm.Position = 0;
FileStream outStream = File.OpenWrite("mapimage" +
index.ToString() + ".png");
memstrm.WriteTo(outStream);
outStream.Flush();
outStream.Close();
bbox.Dispose();
projWGS84.Dispose();
projMercatore.Dispose();
image.Dispose();
map.Dispose();
}
static void Main(string[] args)
{
for (int i = 0; i < 10; i++)
{
DrawAMap(i);
}
}
}
}
///END
It seems there is a big problem with MapScript 6.0.1 (from MS4W) + ASP.NET +
IIS 7.0. Anybody has the same environment? Experiencing problems?

Maybe a permission issue? Sorry, I'm no IIS expert, just guessing...
Maybe try using MS_ERRORFILE "windowsdebug" with tools such as DebugView
and see if that makes any difference?
