Contributor guide:

• Please write here if you would like to pick this up.
• Check out websharper61 branch, build with ./build CI-Release first to prepare everything, then ./build WS-BuildDebug if you want to use Debug mode in VS then run ./build WS-Stop to reset compiler worker.
• Open WebSharper.sln in visual studio
• Files that need the new proxies:
  • https://github.com/dotnet-websharper/core/blob/websharper61/src/stdlib/WebSharper.Main.Proxies/ResultModule.fs
  • https://github.com/dotnet-websharper/core/blob/websharper61/src/stdlib/WebSharper.Collections/MapModule.fs
    You can look up new function original implementations from FSharp.Core source, Map one might need adjustments to fit how WS represents Maps on the client side internally.
• Add unit tests (similar to existing coverage) in
  • https://github.com/dotnet-websharper/core/blob/websharper61/tests/WebSharper.Tests/Result.fs
  • https://github.com/dotnet-websharper/core/blob/websharper61/tests/WebSharper.Collections.Tests/Map.fs
    Run the Web (or equivalent Web.FSharp/Web.Giraffe) project and click Client-side test suite to see QUnit tests running.
