Using method, much more composable than a using statement.

usingMethod.cs

public static class DisposableExtensions
{
    public static R Using<U,R>(this U disposable, Func<U,R> body) where U : IDisposable
    {
        try
        {
            return body(disposable);
        }
        finally
        {
            disposable.Dispose();
        }
    }
}
