Rebex FTP/SSL is also known to work on Windows 8, Windows Vista SP1, Windows XP SP3, Windows Server 2003 R2, Windows Embedded Standard 2009 and Windows Embedded POSReady 2009. However, these platforms already reached end-of-life (most of them many years ago), which means we cannot guarantee support for Rebex FTP/SSL on these operating systems.
Rebex FTP/SSL supports .NET Core platform.
- .NET Core 3.1
- .NET Core 2.1 (end-of-life platform)
Supported operating systems:
Rebex FTP/SSL supports .NET Standard 2.1 on .NET 7.0/6.0/5.0, .NET Core 3.1, Mono 6.10 (or higher), Xamarin.Android 10.1 (or higher) and Xamarin.iOS 13.10 (or higher). It also supports .NET Standard 2.0 on .NET Core 2.1.
- Visual Studio with Xamarin.iOS 13.10 or later
- iOS 10.2 or later
To target Xamarin.iOS platform, reference .NET Standard 2.1 binaries.
- Visual Studio with Xamarin.Android 10.1 or later
To target Xamarin.Android platform, reference .NET Standard 2.1 binaries.
Rebex FTP/SSL can be used within an ASP.NET web page. However, you have to keep in mind specific features of the ASP.NET platform (it is stateless, multithreaded, it may be limited by MediumTrust security level...).
Legacy edition of Rebex FTP/SSL for the following platforms is available as a separate product:
- .NET Compact Framework 3.5/3.9
- .NET Framework 2.0/3.0
Legacy platforms are platforms that are no longer covered by our Standard Support, but have not yet reached End of Life. For details, see the following KB articles:
Rebex FTP/SSL supports .NET Compact Framework on Microsoft's legacy embedded, handheld and mobile platforms based on Windows CE.
- .NET Compact Framework 3.9

Known to work on the following end-of-life operating systems:
- Windows Embedded Compact 7
- Windows Embedded Handheld 6.5
- Windows Embedded CE 6.0
- Windows CE 5.0
- Windows Mobile 5.0, 6.0, 6.1, 6.5
Please note .NET Compact Framework is a legacy platform, which means that Rebex FTP/SSL for .NET CF is available as a separate product with different lifecycle and pricing.
Due to popular demand, we will continue to provide and maintain binaries for .NET Compact Framework 3.5 until 2023-10-10, as long as your legacy support contract remains active. However, support for these binaries is no longer included in the Rebex Support Contract.
