BETA: SUA – “Subsystem for UNIX-based Applications”

I wanted to let you know that we have a new version of SFU available – the component that can be used to port UNIX applications to Windows (Interix) is now called Subsystem for UNIX-based Applications (SUA) and is part of the Windows Server 2003 R2 operating system beta.

The new features are:

  1. Support for AMD-64 – this means that you can now port and run your UNIX scripts and applications on AMD64 hardware and not just x86.
  2. Support for custom UNIX Oracle and SQL Server applications – we have introduced a new paradigm called "mixed-mode programming" that lets UNIX applications link with the Windows client libraries of these databases, e.g. Oracle Call Interface (OCI) for Oracle, and SQL ODBC for SQL Server.
  3. System-V Release 5 (SVR-5) utilities
  4. A Visual Studio debugger add-in to debug ported UNIX applications using the rich Visual Studio debugger. 

This beta is ready now and following are the instructions to sign-up.

  1. Go to and sign-in using your .Net Passport
  2. Select to sign-in using a Guest ID of "WSR2Beta" (case-sensitive – if you experience problems, cut/paste the GuestID rather than typing it)
  3. Complete the nomination survey
