IDisposable Pattern

DbRepository.cs

 public class DbRepository : IDisposable 
 {
    public IDbConnection Connection { get; set; }
    private bool _disposedValue;

    protected virtual void Dispose(bool disposing)
    {
        if (!_disposedValue)
        {
            if (disposing)
            {
                Connection.Dispose();
            }

            // Free unmanaged resources (unmanaged objects) and override finalizer
            // Set large fields to null
            Connection = null;
            _disposedValue = true;
        }
    }

    public virtual void Dispose()
    {
        // Do not change this code. Put cleanup code in 'Dispose(bool disposing)' method
        Dispose(disposing: true);
        GC.SuppressFinalize(this);
    }
 }
