Blazor NavLink style with a class in CSS Isolation

I am trying to style NavLink in Blazor with a CSS class that I have in a CSS Isolation file for that razor file. I just do not seem able to make any changes accept with global or inline styles.

sample.razor

<NavLink href="" class="cssLink">A Link</NavLink>

sample.razor.css

.cssLink {  color: #10069f;  text-decoration: none;  transition: all 0.1s linear;}.cssLink:hover {  color: #4a4a4a;  text-decoration: none;}
