Incompatible external console protocol version 4

Hi - I am using WinSCP.dll (1.0.0.528) in .NET 4.0 to run the sample program given on the site. All the input parameters work with the GUI version of WinSCP. However, when I run my program using the .net assembly, I get the following message at "session.Open(sessionOptions)".

Version of GUI based WinSCP installed on my machine is 4.2.7 and I using the WinSCP .NET assembly having version 1.0.0.528.

Please advise[/img]

You have to use the same version of the assembly as WinSCP.

You are right..Finaly I got it working by using the below version combination: -
WinSCP.exe - 5.0.7
WinSCP.dll - 1.0.0.235

Thanks for creating the dll. It's very handy for a developer to write managed code.
