DotVVM syntax is different from Razor. Instead of the @if statement, use the Visible property on any HTML element and bind it to a boolean expression.

// Razor
@if (orders.Count == 0)
{
    <div class="order-list">
        <h2>No orders placed</h2>
    </div>
} 

// DotVVM
<div class="order-list" 
     Visible="{value: Orders.Count == 0}">
    <h2>No orders placed</h2>
</div>

There is also IncludeInPage with a similar meaning. The Visible property just hides the element using CSS display property while IncludeInPage removes it from the DOM.
