This fork of PebbleSharp is intended specifically for use on mono with the bluez 5 bluetooth stack. It is also meant for use on a raspberry pi (ARMHF), but that is probably not important, I believe it would work fine on any linux/bluez/mono installation. (It definitely works on ubuntu)
If you are looking for wheezy or bluez 4 compatibility, you are looking for https://github.com/brookpatten/PebbleSharp/tree/e258667861a15d86ff1179c0f0dffe2acaa1b1f5
It also has additional functionality in pebblesharp.core for the following
- AppMessage Send/Receive
- Updated bundle format to support platform specific subdirectories
- BlobDB support for notifications
- BlobDB support for app installs
- Added various enums for things like hardware platform etc
