Using CSharp Mapscript with VS2005 and .NET 2.0

[David Lowther]

I ended up with all the DLLs in the output dir for my winapp. And still had
problems until Tamas provided me with a "built for .NET 2.0" set of stuff.

 

I've got a test app that I passed around with Tamas that I think has
everything you need in it to get working.

 

I added a comment to the Mapserver Wiki at:

http://mapserver.gis.umn.edu/docs/howto/mapscriptcscompile/howto_view

 

This has a link to download the test app that Tamas helped me get working. 

 

I've also managed to get things working in ASP.NET 2.0 (against all the best
advice of folks regarding thread safety...). Maybe I'll post a test app for
that too sometime.

 

 

Good luck!

Hi,

 

This kind of problem might be dedicated to missing libraries

referenced by the mapscript package. You might want to use

sysinternal's filemon or a similar tool to detect the dll-s could not

be loaded. I suggest to place all the dll-s into your application

directory (where mapscript.dll and mapscript_csharp.dll resides)

 

You should also recompile mapserver and mapscript with VS2005 to make

sure mapscript_csharp.dll targets the MS.NET FW 2.0 instead of 1.1.

The windows buildkit is the best choice to have all the files needed

for the compilation

Best Regards,
