Usage

Disposable

using DisposableHelpers;

namespace YourNamespace
{
    public class SampleDisposable : Disposable
    {
        private SampleUnmanagedResource resources;
        
        protected override void Dispose(bool disposing)
        {
            if (disposing)
            {
                resources.Release();
            }
            base.Dispose(disposing);
        }
    }
}

Disposable Source Generator

using DisposableHelpers.Attributes;

namespace YourNamespace
{
    [Disposable]
    public partial class SampleDisposable
    {
        private SampleUnmanagedResource resources;
        
        protected void Dispose(bool disposing)
        {
            if (disposing)
            {
                resources.Release();
            }
            base.Dispose(disposing);
        }
    }
}

Anonymous Disposable

using DisposableHelpers;

namespace YourNamespace
{
    public static class Program
    {
        private static SampleUnmanagedResource resources;
        
        public static void Main(string[] args)
        {
            Disposable disposable = new Disposable(disposing =>
            {
                if (disposing)
                {
                    resources.Release();
                }
            });

            disposable.Dispose();
        }
    }
}

AsyncDisposable

using DisposableHelpers;

namespace YourNamespace
{
    public class SampleAsyncDisposable : AsyncDisposable
    {
        private SampleAsyncUnmanagedResource resources;
        
        protected override async ValueTask Dispose(bool isDisposing)
        {
            if (isDisposing)
            {
                await resources.Release();
            }
            return base.Dispose(isDisposing);
        }
    }
}

AsyncDisposable Source Generator

using DisposableHelpers.Attributes;

namespace YourNamespace
{
    [AsyncDisposable]
    public partial class SampleAsyncDisposable
    {
        private SampleAsyncUnmanagedResource resources;
        
        protected async ValueTask Dispose(bool isDisposing)
        {
            if (isDisposing)
            {
                await resources.Release();
            }
            return base.Dispose(isDisposing);
        }
    }
}

Anonymous AsyncDisposable

using DisposableHelpers;

namespace YourNamespace
{
    public static class Program
    {
        private static SampleAsyncUnmanagedResource resources;
        
        public static async void Main(string[] args)
        {
            AsyncDisposable disposable = new AsyncDisposable(async disposing =>
            {
                if (disposing)
                {
                    await resources.Release();
                }
            });

            await disposable.DisposeAsync();
        }
    }
}
