- 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`.
