All active ServiceStack libraries and NuGet packages are now being developed and maintained in ServiceStack’s mono repo at:
https://github.com/ServiceStack/ServiceStack
The new Mono repo has greatly simplified all maintenance efforts around ServiceStack’s code base, including building, contributing and debugging, where there’s now only 1 repo that needs to be checked out to make changes to any ServiceStack package.
You can learn more about the new Mono repo structure & debugging/building benefits from:
