What is IAsyncDisposable?

IAsyncDisposable is an interface in C# introduced for asynchronous resource cleanup. It extends the IDisposable concept, allowing cleanup operations that can be asynchronous, such as closing network connections, files, or releasing other resources that require waiting.

Main method of the interface:

ValueTask DisposeAsync();

Example usage:

public class AsyncResource : IAsyncDisposable
{
    public async ValueTask DisposeAsync()
    {
        // Asynchronous cleanup, e.g., closing a connection
        await CloseConnectionAsync();
    }

    private Task CloseConnectionAsync()
    {
        // Simulate an asynchronous operation
        return Task.Delay(100);
    }
}

// Usage
await using var resource = new AsyncResource();
// ... work with the resource

This approach improves resource management in asynchronous code, avoiding blocking and efficiently releasing resources.
