SharpSVN2019 is fork of the original CollabNet project
The SVN repository of the CollabNet project is at
https://ctf.open.collab.net/svn/repos/sharpsvn/trunk/
It is my intention to create a version which compiles using Visual Studio 2019, without consideration of older versions of Visual Studio.
Version 1.12.0.1 is now available as a nuget package at
https://www.nuget.org/packages/SharpSvn2019.SharpSvn/
This version is built against SVN version 1.12.
