Log File not being created

I'm not sure what I am doing wrong. I have a power script that uses the below code. It won't create the log file. The folder exists, and I have full rights to it. I can created and delete files there just fine. I am using 5.7.6

# Load WinSCP .NET assembly
Add-Type -Path "C:\Program Files (x86)\WinSCP\WinSCPnet.dll"

# Setup session options
$sessionOptions = New-Object WinSCP.SessionOptions
$sessionOptions.Protocol = [WinSCP.Protocol]::ftp
$sessionOptions.HostName = "65.82.131.58"
$sessionOptions.UserName = "*****"
$sessionOptions.Password = "*****"
$session = New-Object WinSCP.Session
$session.SessionLogPath = "C:\WinSCPLogs\test.xml"

try
{
# Connect
$session.Open($sessionOptions)

FYI I just tried 5.7.7 still no luck (as well as the new 5.7.7 .NET dll). I know the code is executing, because at the end I do a send-mail and that comes through.

Still not sure why it is not logging, but I figured out the issue that I needed the log. Remote folder path is case sensitive. I'd like to get the logging working, but it can be prioritized lower.

WinSCP get confused by the .xml extension. You have to use another one. The session log is not XML, it's a plain text file. Use for example "C:\WinSCPLogs\test.log".
