[mapguide-users] Create Featuresource

Hi Kenneth,

thank you for your clarification. I've got it running with the solution you
mentioned. I added an entry to the PATH env variable that points to the bin
folder of my FDO SDK. That's a solution for my development environment. But
when I release our WebApplication to our costumers I think I can't convince
them to first download the FDO SDK and then set an environment variable. Any
Idea?

By the way, what is the difference between the FDO dll's and the MapGuide
dll's. 
When I reference the MapGuideDotNetApi.dll I also have to copy the c++ dll
into the bin folder. That works fine. Obviously the "windows dll location
algorithm" looks into the bin folder.
With the FDO libraries (managed / unamanged) I see no difference. I should
be able to add the reference to all managed libraries and then put the
appropriate c++ dll into the bin folder. Why does this scenario fail?

Thanks, Gunter
