Re: What is the solution ?

@PathruduMajji: You have to download WinSCP 5.14 RC for .NET Core support.

For information about using the assembly in Azure Function, see also:

What is the solution ?

2019-03-05 12:31

Hi Guys,

Finally what is the solution for this issue. I did not find anything from above discussion.

I had an Azure function which i am hosting in Azure. I installed WinSCP 5.13.8 from NuGet package manager. When I run this code in local, it is working fine. But this throwing above method not found error once I hosted the function and ran it from AZURE.

ERROR: System.MissingMethodException: Method not found: 'Void System.Threading.EventWaitHandle..ctor(Boolean, System.Threading.EventResetMode, System.String, Boolean ByRef, System.Security.AccessControl.EventWaitHandleSecurity)'.

Edit: Sorry for the confusion. It is not working in my local either. Do I need to add any packages? Please help me out.

Re: Downloaded 5.14.1 Beta still getting error

2018-11-10

@croffers: Download ".NET assembly" package:
https://winscp.net/eng/downloads.php#stable_automation

(Not the installer – which does not include .NET Standard build of the assembly)

Downloaded 5.14.1 Beta still getting error

2018-11-09 17:27

I downloaded the 5.14.1 Beta and I'm still receiving this error:

Method not found: 'Void System.Threading.EventWaitHandle..ctor(Boolean, System.Threading.EventResetMode, System.String, Boolean ByRef, System.Security.AccessControl.EventWaitHandleSecurity)'.

Was the right version of the dll included in the Beta download?

I'm using .NET Core 2.1

Thanks, Craig

I'll look into it in few days. Once I have anything to test, I'll contact you.

Though note that there's no way to make the assembly working on other system than Windows.

MissingMethodException in Session.Open error in .NET Core 2.0

2018-04-13 15:38

While running this C# code (.NET Core 2.0.3), the app throws System.MissingMethodException when I get to this line: session.Open(sessionOptions)
Using WinSCP 5.13.1.0
My code:

SessionOptions sessionOptions = new SessionOptions
{
  Protocol = WinSCP.Protocol.Sftp,
  HostName = "10.22.111.12",
  PortNumber = 22,
  UserName = "ec2-user", // this is on AWS.  linux EC2 instance 
  SshHostKeyFingerprint = "ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:..."
};
using (Session session = new Session())
{
  session.DebugLogPath = @"C:\Projects_c#\AWS\consoleApp\AMFConsoleApp\log.txt"; 
  session.Open(sessionOptions); // I get the error right here
  session.MoveFile(filePath, "10.22.111.12/appdata/content");
  session.Close();                      
}
