Does anyone know how I get that to run? I'm pretty sure I need to compile it with something but I just don't know what or how.
This is written in C#, You can compile it using Visual Studio version that would allow You to compile against .NET frameworks 3.5 and 4.0.
Visual Studio 2010 or newer will be enough.
You can download free Visual Studio 2013 for Desktop here
update: Managed to build it. First I removed pre-build event from LoLNotes project properties as this is the one that calls gitExport.exe (I'm pretty sure You don't need it). Then I needed to re-add some certificate file to LoLNotes project as it couldn't find it even though it was there. After that solution builds successfuly.
