- #3918
- precompute size of `StringBuilder` in `ExpressionHelper`
- reduce `string` allocations in `ViewDataEvaluator`
- also get rid of `Enumeration` state machines
- reduce the size of a few objects; use more expression-valued properties
- e.g. don't store `_modelType` in `ModelExplorer`
- add `EmptyArray<TElement>`; make empty arrays consistently `static`
- avoid `string.Split()` in HTML and tag helpers
nits:
- make `ExpressionHelperTest` tests more stringent
- correct `Message` for an `ArgumentNullException`
- remove excess `using`s in classes I touched (but often ended up leaving otherwise unchanged)
- improve doc comments
- remove `ToString()` call on a `string`
- avoid encoding `string.Empty`
- fix test file name
- remove useless variables
- correct spelling
- improve whitespace
- #2969
- `RemoteAttribute` did not support `IStringLocalizer` overrides
- use same `MvcDataAnnotationsLocalizationOptions` property as for other `ValidationAttribute`s
- error message `NumericClientModelValidator` added could not be overridden
- not related to `IStringLocalizer` because users have no way to set the resource lookup key
- extend `IModelBindingMessageProvider` to add the necessary `Func<,>`
- also correct problem using resources with `RemoteAttribute` and add lots of tests
This change removes a layer of abstraction. These validators now just do
what they do now without creating a bunch of intermediate objects.
ModelClientValidationRule has been removed, and client validations
manipulate the attributes collection of a tag directly.
