Neat as Unconstrained Melody was, it was very much hacked together.
The enums part of it was always more compelling to me than the delegate part, and
Tyler Brinkley has done a better job of implementing that in his Enums.NET
project. Importantly, the NuGet package for Enums.NET supports
.NET Core by targeting netstandard1.0. I looked into doing the same thing for Unconstrained Melody
(as did Nick Craver - thanks!) but it's too much work for too little benefit compared with rallying
round Enums.NET and its accompanying corefx proposal.
I don't expect to publish any more releases of Unconstrained Melody.
Full documentation may come later, if there's enough demand.
For the moment, read this blog post: http://codeblog.jonskeet.uk/2009/09/10/generic-constraints-for-enums-and-delegates/
Then if you just want the library, install the NuGet package: http://nuget.org/List/Packages/UnconstrainedMelody
Or if you want the "Constraint Changer" to write your own generic members in the same way, build the source code from the project home page: http://code.google.com/p/unconstrained-melody/
