Escaping @ in Blazor
Quoting Razor syntax:
To escape an @ symbol in Razor markup, use a second @ symbol:
<p>@@Username</p>
The code is rendered in HTML with a single @ symbol:
<p>@Username</p>
Just add another @ symbol. So your exmaple:
wwwroot/lib/@@icon/open-iconic/icons/account-login.svg
will render as:
wwwroot/lib/@icon/open-iconic/icons/account-login.svg
