If/else is not working properly with using OnInitiliazedAsync in Blazor C#

Question

<div class="form-inline justify-content-center mt-4">
    @if (Products != null && Products.Any())
    {
        @foreach (var product in Products)
        {
            #MyCode
        }
    }
    else 
    {
        <h2>This Store has no Products :)</h2>
    }
</div>
@code
{
    [Parameter]
    public int Id { get; set; }

    public IEnumerable<ProductDTO> Products { get; set; }
    protected override async Task OnInitializedAsync()
    {
        Products = await Store.GetStoreProducts(Id);
    }
}

It first show the else part and then load the if part ( if products are available ). It should work like that if products are available then else part shouldn't be loaded.
