5.2 Beta of .NET assembly not renamed

When I downloaded the WinSCP 5.2 Beta of the .NET assembly from https://winscp.net/download/winscp520automation.zip/download
the extracted files contained a DLL named "WinSCP.dll". I would have expected this DLL to be renamed to "winscpnet.dll" as per the release notes on https://winscp.net/eng/docs/history_old#5.2
- "Renamed WinSCP .NET assembly to winscpnet.dll to avoid conflicts with winscp.exe. 945"

Thanks for your report.
I'll fix this in 5.2.1.
