System.MissingMethod exception with AngleSharp 0.9.4

[rmichela]

After updating to AngleSharp 0.9.4, HtmlSanitizer.Sanitize() started throwing a MissingMethodException.

Method not found: 'System.String AngleSharp.IStyleFormattable.ToCss()'
at Ganss.XSS.HtmlSanitizer.SanitizeStyle(IHtmlElement element, String baseUrl)
at Ganss.XSS.HtmlSanitizer.Sanitize(String html, String baseUrl, IMarkupFormatter outputFormatter)

Reverting to AngleSharp 0.9.3 fixed the problem.

I think angelsharp isn't following semver then.

The method was moved from the interface to an extension method in AngleSharp/AngleSharp@59d98f0, causing binary incompatibility. Recompiling fixes it. Will release a new version shortly.

Ow the apply to semver I see:

Major version zero (0.y.z) is for initial development. Anything may change at any time. The public API should not be considered stable.
