I have been using this client for some time. It's an awesome library.
I am doing a simple upload via streaming.
Usually, when I am uploading I use the physical path method as I have the file physically.
Currently, I am downloading the file from one location and uploading it to another location.
Using this method avoids creating unnecessary files locally.
I am getting an error on this line.
https://github.com/winscp/winscp/blob/5.18.2-beta/dotnet/Session.cs#L823
I am not familiar with the internals but I looking at code.
I think this check is incorrect.
this._process.StdIn is going to be null in the beginning.
Below is my code for calling this method.

public void UploadFile(Stream stream, string remotePath)
{
// Setup session options
var sessionOptions = new SessionOptions
{
Protocol = Protocol.Ftp,
HostName = FtpHostName,
UserName = FtpUser,
Password = FtpPassword
};
using Session session = new Session();
// Connect
session.Open(sessionOptions);
if (session.Opened)
{
session.PutFile(stream, remotePath);
}
}
