- Now allow the attribute to exist on `img` and `source` tags.
- Updated existing `UrlResolutionTagHelper` functional test to validate `srcset` attribute.
#2964
- Razor rendering now understands `TagMode` which allows void elements to be rendered.
- Added a `TagStructure.WithoutEnd` bit to `InputTagHelper`, `ImageTagHelper` and `UrlResolutionTagHelper`. This will allow users to write the various elements in the void format. Used the HTML5 spec to determine the elements appropriate.
- Added tests to ensure `TagMode.StartTagOnly` is rendered properly.
- Updated a few functional tests to showcase the void element formats.
aspnet/Razor#450
- Razor removed the ability to automatically resolve URLs prefixed with `~/`; therefore `ScriptTagHelper`, `LinkTagHelper` and `ImageTagHelper` have changed to take in `IUrlHelper`s and auto-resolve their URL based properties if they start with `~/`.
- Added a catch-all `~/` resolver for non `TagHelper` based HTML elements. Razor used to resolve any attribute value that started with `~/` now the behavior is restricted to attributes that can contain URLs.
- Updated `IUrlHelper` to accept `null` values.
- Added functional tests to validate that URLs resolve correctly.
- Updated `TagHelper` tests to ensure that URLs are resolved via an `IUrlHelper`.
