What this installs / configures:
- - WinMerge on the user PATH
+ - WinMerge on the user PATH (x64 only)
- vswhere.exe on the user PATH: the Visual Studio installer puts it in
%ProgramFiles(x86)%\Microsoft Visual Studio\Installer, which nothing adds
to the PATH, so build scripts (and VsDevCmd.bat itself) complain that
'vswhere.exe' is not recognized
- BinSkim (binary hardening analyzer) in %LOCALAPPDATA%\Programs\BinSkim,
- on the user PATH
+ on the user PATH (x64 only - the NuGet package publishes win-x64 alone)
- Global git identity, and core.sshCommand pointed at a Win32-OpenSSH
client so git shares the Windows ssh-agent: the fast ssh.exe the elevated
half unpacks beside rsync.exe if it is there, the in-box one otherwise
+ - An architecture audit: the real PE machine type of every tool this box
+ provisions, resolved the way a shell would. Informational, never fatal.
+ Anything running emulated without a listed reason is called out.
