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