Missing SupressFinalize in Dispose

[vpenades]

The proper dispose pattern requires a GC.SupressFinalize to prevent the dispose to be called two times:

 public void Dispose()
 {
            Dispose(true);
            GC.SuppressFinalize(this);
 }

 protected virtual void Dispose(bool disposeManagedResources)
 {
            if (disposeManagedResources)
            {
                this.Close();
            }
 }
