Commented Issue: Remote File exists not working [1574]

I've tried to use sftp.Exists(String) do not work for files. Already tested for file and for directory. Directory work well, but files are not recognized.

my changing the beloow method in sftpclient.cs from

public bool Exists(string path)
{
if (path.IsNullOrWhiteSpace())
throw new ArgumentException("path");

if (this._sftpSession == null)
throw new SshConnectionException("Client not connected.");

var fullPath = this._sftpSession.GetFullRemotePath(path);

if (this._sftpSession.RequestRealPath(fullPath, true) == null)
{
return false;
}
else
{
return true;
}
}

to

public bool Exists(string path)
{
if (path.IsNullOrWhiteSpace())
throw new ArgumentException("path");

if (this._sftpSession == null)
throw new SshConnectionException("Client not connected.");

var fullPath = this._sftpSession.GetCanonicalPath(path);

// Try to open as a file
var handle = this._sftpSession.RequestOpen(fullPath, Flags.Read, true);

if (handle == null)
{
handle = this._sftpSession.RequestOpenDir(fullPath, true);
}

if (handle == null)
{
return false;
}
else
{
this._sftpSession.RequestClose(handle);
return true;
}
}

the new code was taking form a old version of sshnet library.
good luck to all
