  • Same DLLs for all platforms (32-bit x86, 64-bit x64, ARM)

.NET Standard 

Rebex HTTPS supports .NET Standard 1.5/2.0 on .NET Core. It also supports .NET Standard 2.0 on Mono 5.14 (or higher). Support for .NET Standard 2.0 on Universal Windows Platform (build 16299 or higher) and Xamarin.Mac (version 3.8 or higher) is experimental.

Mono on Linux

Xamarin.Mac 

Rebex HTTPS features experimental support for Xamarin.Mac 3.8 or later via .NET Standard 2.0.

Universal Windows Platform 

Rebex HTTPS features experimental support for Universal Windows Platform (UWP/UAP) applications on Windows 10 via .NET Standard 2.0.

Supported platforms:

  • Windows 10 (version 1709 or higher)
  • Windows 10 IoT (version 1709 or higher)

In order to use Rebex HTTPS on these platforms, make sure to specify at least Windows 10 Fall Creators Update (10.0; Build 16299) in your Universal Windows project.

ASP.NET 

Rebex HTTPS 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, multi-threaded, it may be limited by MediumTrust security level...).

Further info on using Rebex components in web environment can be found in How to use Rebex SFTP or FTP/SSL in ASP.NET knowledge base article. The article discusses SFTP and FTP/SSL, but implications for Rebex HTTPS component are the same.

Legacy platform support 

Legacy edition of Rebex HTTPS for the following platforms is available as a separate product:

  • .NET Compact Framework 3.5/3.9

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:

.NET Compact Framework 

Rebex HTTPS supports .NET Compact Framework on Microsoft's legacy embedded, handheld and mobile platforms based on Windows CE.

Supported frameworks:

  • .NET Compact Framework 3.9
  • .NET Compact Framework 3.5

Supported operating systems:

  • Windows Embedded Compact 2013
  • Windows Embedded Compact 7
  • Windows Embedded Handheld 6.5
  • Windows Embedded CE 6.0 (end-of-life platform)
  • Windows CE 5.0 (end-of-life platform)
  • Windows Mobile 5.0, 6.0, 6.1, 6.5 (end-of-life platforms)

Supported IDE versions:

  • Microsoft Visual Studio 2013
  • Microsoft Visual Studio 2012
  • Microsoft Visual Studio 2008

Please note .NET Compact Framework is a legacy platform, which means that Rebex HTTPS for .NET CF is available as a separate product with different lifecycle and pricing.
