For anyone who comes across this thread in the future, you should know that I've figured out a way to package ScintillaNET as a NuGet package (including the unmanaged DLLs we need to distribute), however, there is already a package named "ScintillaNET" in the NuGet repository that is NOT maintained by us. I've attempted to work with the NuGet team to get this package removed or control of it given to us. You can follow the discussion here: https://nuget.codeplex.com/discussions/562170.
