Prerendering might be useful for other pages that don't use `localStorage` or `sessionStorage`. To retain prerendering, defer the loading operation until the browser is connected to the circuit. The following is an example for storing a counter value:

:::moniker range=">= aspnetcore-5.0"
:::moniker range=">= aspnetcore-9.0"

```razor
@using Microsoft.AspNetCore.Components.Server.ProtectedBrowserStorage
@inject ProtectedLocalStorage ProtectedLocalStore

@if (RendererInfo.IsInteractive)
{
<p>Current count: <strong>@currentCount</strong></p>
<button @onclick="IncrementCount">Increment</button>
}
else
{
<p>Loading...</p>
}

@code {
private int currentCount;

protected override async Task OnInitializedAsync()
{
if (RendererInfo.IsInteractive)
{
await LoadStateAsync();
}
}

private async Task LoadStateAsync()
{
var result = await ProtectedLocalStore.GetAsync<int>("count");
currentCount = result.Success ? result.Value : 0;
}

private async Task IncrementCount()
{
currentCount++;
await ProtectedLocalStore.SetAsync("count", currentCount);
}
}
```
