## GetConnectionStringAsync(CancellationToken)

- Name: `GetConnectionStringAsync(CancellationToken)`
- Returns: `ValueTask<string?>`
- Source: [GitHub](https://github.com/CommunityToolkit/Aspire/blob/d479e13473b1d29d06b974f144a0049289a3cb5c/src/CommunityToolkit.Aspire.Hosting.K3s/K3sServiceEndpointResource.cs#L103-L106)

Returns the host-accessible service URL, or `null` if the port-forward is not yet active.

```csharp
public sealed class K3sServiceEndpointResource
{
    public ValueTask<string?> GetConnectionStringAsync(
        CancellationToken cancellationToken = default(CancellationToken))
    {
        // ...
    }
}
