Richard,

I've managed to make GDAL with C# bindings working:

http://mateusz.loskot.net/tmp/gdal-csharp-works.png

So, I can confirm current version of GDAL from SVN and C# interfaces
does work.

In my case, the problem was that some of DLL dependencies were not in
PATH while I was executing C# version of ogrinfo.exe or createdata.exe.

What Tamas already suggested, please could you check if all libraries
used by your compilation of GDAL are available in PATH?
In my case, I didn't have GEOS DLL in PATH, so please walk through
dependencies like MySQL, PostgreSQL, GEOS, etc. (if built in to your
GDAL) and see if they are reachable.

Cheers
