Move ASP.NET WebHooks code to new aspnet/AspNetWebHooks repo

[dougbu]

The AspNetWebHooks.sln and WebHooks.sln projects have very little in common. And, though ASP.NET WebHooks packages may ship simultaneously with ASP.NET Core WebHooks packages in the next release, such timing is not guaranteed going forward.

Details

• [x] mirror the aspnet/WebHooks repository to aspnet/AspNetWebHooks
  • [x] create the target repository
• update Readme files to describe specifics of separate repos and to link to each other
  • [x] aspnet/WebHooks (25473ff424)
  • [x] aspnet/AspNetWebHooks (aspnet/AspNetWebHooks@e79fd8a8d7)
• remove all now-unnecessary files and infrastructure
  • [x] aspnet/WebHooks (7e41807d92)
  • [x] aspnet/AspNetWebHooks (aspnet/AspNetWebHooks@f3d20f8c76)
• [x] add BuildTools infrastructure to aspnet/WebHooks (25473ff424)
• [x] update ASP.NET Core WebHooks version to 1.0.0-preview1 (25473ff424)
  • [x] update dependencies to align with ASP.NET Core 2.1.0-preview1 milestone (69a0ad7c11)
• [x] update ASP.NET WebHooks version to 1.3.0-preview1 (aspnet/AspNetWebHooks@e79fd8a8d7)
• add or update milestones
  • [x] aspnet/WebHooks
  • [x] aspnet/AspNetWebHooks
• [x] copy or move applicable issues to aspnet/AspNetWebHooks repo
  • may make other choices for the two sets of issues, especially those closed in the existing 2.0.0-preview1 milestone

[dougbu]

This work is part of the 2.0.0-preview1 milestone aka ASP.NET Core WebHooks 1.0.0-preview1 and ASP.NET WebHooks 1.3.0-preview1.

Oops, temporarily assigning to @Eilon

[dougbu]

Removing @Eilon because he's done his part. Thanks!

[dougbu]

aspnet/AspNetWebHooks repo is now building end-to-end. Post-split packages from this repo are now available in https://dotnet.myget.org/gallery/aspnetwebhooks.

aspnet/WebHooks#232 should get aspnet/WebHooks repo building reliably locally, on AppVeyor, and on Travis. Builds on internal CI should come soon after though signing may take a bit longer.

[dougbu]

Assigning back to @Eilon. @Eilon please run your issue mover tool.

Please LMK if referenced milestones need to exist in aspnet/AspNetWebHooks first. I can do that part.

[Eilon]

@dougbu moving this back to your plate to check if anything else needs to be done, then close.

[dougbu]

All set. In the background, I'll remove the duplicate ASP.NET WebHooks releases and tags from this repo.
