.net - What GPS Dongles Work With Windows 7 And The .Net 4.0 System.Device.Location Namespace

Jun 29, 2010

I want to add full GPS support into my application. The .Net 4.0 System.Device.Location namespace information here is perfect for my needs. When this was first announced and the Beta release was out, I got a GPS dongle, but I could never get Windows 7 to see it as a sensor and therefore make use of System.Device.Location. After many e-mails to Microsoft they would only confirm that they were using the GPS dongle that comes with a M$ Mapping product..

Does anyone know of any other Dongles that definately will appear as a sensor in Win7? I like the look of this one, it gets good reviews and is a nice size.Is there anyway of knowing that it will work, for example what Chipsets are supported as a Windows 7 Sensor, a lot of the information out there says that the Win7 implementation is really lacking..
