Is there an equivalent to Html.Raw in Blazor?

Not right now, but will have it probably in the next version: Follow this

Workaround (from that issue):

cshtml

    

    @functions{
        [Parameter] string Content { get; set; }
        private ElementRef Span;

        protected override void OnAfterRender()
        {
            Microsoft.AspNetCore.Blazor.Browser.Interop.RegisteredFunction.Invoke("RawHtml", Span, Content);
        }
    }

index.html

        
            Blazor.registerFunction('RawHtml', function (element, value) {
                element.innerHTML = value;
                for (var i = element.childNodes.length - 1; i >= 0; i--) {
                    var childNode = element.childNodes[i];
                    element.parentNode.insertBefore(childNode, element);
                }
                element.parentNode.removeChild(element);
                return true;
            });
