Hi,

It seems that the GEOS support is not actually enabled in your
project. In this case the Intersect method tests the overlapping of
the envelopes of the 2 geometries.

Are you sure the correct version of the dll-s have been loaded?

In the recent days I've changed the csharp bindings to link against
gdal14.dll instead of the static linking. The previous approach might
lead to various problems. Checkout the latest svn-trunk to rely on
these changes.

Best regards,

Tamas
