[postgis-users] PostGIS and ADO.NET

[Abe Gillespie]

Hello Jeff,

There is no *direct* support per se (at least none that I know of).
But you can use Npgsql as the ADO.NET data access driver and retrieve
the shape data as byte arrays.  To get instantiated shape objects
you'll then have to feed the byte array into libraries such as
NetTopolgySuite (http://nts.sourceforge.net/), SharpMap
(http://www.codeplex.com/SharpMap/), or consume the byte arrays
directly in your code as is done in zigGIS
(http://code.google.com/p/ziggis/).

You'll have to write your SQL spatial queries by hand.  But I suspect
you'll want to do this anyway.

Good luck!
