3.5.8

  • Removed overload of ViewModel<_,_>.ToString because of slow performance (#370)

3.5.7

  • Excluded 4.* prereleases from possibilities for version of Elmish dependency
  • Added support for multiple validation errors
  • Added target net5.0-windows
  • ViewModel<'model, 'msg> now overrides object.ToString() and returns a string representation of the current 'model instance. This is only intended for deubgging. No guarantees are given about the exact structure of the returned string.
  • Fixed incorrect spelling of a word in a log message

3.5.6

  • The amount of time used to update OneWaySeq and SubModelSeq bindings has been significantly decreased. This includes all cases of a SubModelSeq binding and all cases of a OneWaySeq binding for which equals returns false.

3.5.5

  • Fix exception when showing sub-windows as part of init

3.5.4

  • Windows may now be created on any thread

3.5.3

  • Fix crash when init returns a command opening a subModelWin

3.5.2

  • Improved error handling when collection bindings contain duplicates

3.5.1

  • Improve performance of Binding.oneWaySeq, Binding.oneWaySeqLazy, and Binding.subModelSeq

3.5.0

  • Add netcoreapp3.0 target

3.4.1

  • Corrected type parameter of getId in oneWaySeqLazy

3.4.0

  • Make model/dispatch available to getWindow in Binding.subModelWin

3.3.0

  • Added optional dispatch wrapper to two-way bindings and command bindings, which allows dispatches to be throttled/debounced etc.

3.2.1

  • Fixed ElmConfig.MeasureLimitMs not being used

3.2.0

  • Added proper dialog/window support using Binding.subModelWin. See the readme for more and the NewWindow sample for an example.
  • Deprecated Cmd.showWindow (use Binding.subModelWin instead)

3.1.0

  • Added Program.withDebugTrace which is similar to withConsoleTrace but writes using System.Diagnostics.Debug.WriteLine (e.g. to the VS output window)

3.0.0

  • The most massive (and hopefully useful) update yet!
  • Breaking: Overload-based syntax for Binding. The old Binding module is deprecated and renamed to BindingFn. The new Binding is a static class with static methods, providing many overloads for flexibility. To migrate, replace all occurrences of Binding. with BindingFn. and follow the deprecation warnings.
  • Breaking: The Elmish.Uno.Internal namespace has been removed and everything in it that should actually be internal has been marked internal. This includes ViewModel.
  • Breaking: Elmish.Uno.Internal.BindingSpec<_,_> has been moved/renamed to Elmish.Uno.Binding<_,_>. It should thus be more pleasant to use in type annotations.
  • Breaking: Elmish.Uno.Utilities.ViewModel.designInstance has been moved to Elmish.Uno.ViewModel. Furthermore, it returns obj since ViewModel is internal.
  • Breaking: Removed twoWayIfValid. It hasn’t worked for a while due to core Elmish internals, and was of suspect utility anyway.
  • New: Many more helpful Binding signatures available due to the new overload-based syntax.
  • New: More general Binding.subModel and Binding.subModelSeq overloads that allow a more idiomatic Elm architecture even with static views. For background information, see #86 (the issue is otherwise outdated).
  • New: Sticky subModelOpt bindings that returns the last non-null model when model is None (useful when animating out stuff)
  • New: elmEq and refEq as useful equality defaults for lazy bindings. elmEq efficiently uses reflection to do a comparison for each member that is referential for reference types except strings, and structural for strings and value types.
  • New: Program.mkSimpleWpf and Program.mkProgramWpf with more WPF-friendly signatures.
  • New: Program.mkProgramWpfWithCmdMsg for easily following the CmdMsg pattern to allow testable commands. See the FAQ in the readme for details.
  • New: Cmd.showWindow helper to open a new window.
  • New: Slow calls can be logged (configurable threshold).
  • New: Made available Program.startElmishLoop which is a low-level function that starts an Elmish loop given an Elmish Program and a WPF FrameworkElement. You probably won’t need it.
  • Improvement: Logs now indicate the binding path.
  • Improvement: Possibly better performance due to internals now using ValueOption instead of Option.
  • Improvement: Finally added (lots of) unit tests, so confidence of correct functionality is higher. (No critical bugs were found when creating the tests.)

2.0.0

  • No changes, but updated for Elmish 3.0 so the package can finally move out of beta

2.0.0-beta-11

  • Add Binding.subModelSelectedItem

2.0.0-beta-10

  • Fix checkboxes erroneously being shown as failing validation (#78) by @BillHally
  • The above fix also fixes binding warnings for two-way bindings

2.0.0-beta-9

  • Add new bindings oneWayOpt and twoWayOpt (#75)
  • Update to Elmish 3.0.0-beta-7

2.0.0-beta-8

  • Add new binding subBindingSeq, see readme for details.

2.0.0-beta-7

  • Fix Elmish dependency version in nuget spec

2.0.0-beta-6

  • Update to Elmish 3
  • Dispatch on UI thread to block instead of getting weird UI behaviour from race conditions when updates take too long

2.0.0-beta-5

  • Fix subModelSeq items being unselected during updates

2.0.0-beta-4

  • Breaking: Change order of oneWayLazyWith arguments to and rename it to oneWayLazy, removing the existing oneWayLazy function. The rationale is explained in #60 . To migrate from 2.0.0-beta-3 to 2.0.0-beta-4: Add (=) as the equals parameter to oneWayLazy usages, and rename oneWayLazyWith usages to oneWayLazy.
  • Add Binding.oneWaySeqLazy

2.0.0-beta-3

  • Add convenience function to create design-time VMs

2.0.0-beta-2

  • Improve log messages

2.0.0-beta-1

  • Complete rewrite, several breaking changes and new features
  • twoWayValidation is called twoWayIfValid (because that’s what it is, and it clearly separates it from the new twoWayValidate)
  • oneWayMap is called oneWayLazy (its implementation has changed, and the use case has expanded, but is similar)
  • cmd and cmdIf have been renamed paramCmd and paramCmdIf, because the old names have new signatures/use-cases
  • model has been renamed subModel because it’s more clear, and consistent with the new subModelOpt and subModelSeq
  • Program.runDebugWindow has been removed in favour of Program.runWindowWithConfig
  • Bundled Elmish has been removed, and Elmish 2.0 is used as an external dependency
  • Any Application instance instantiated before calling Program.run... will now be used
  • Several new functions in the Binding module; dot into it in your IDE or see the repository for samples or source code
