After 6 previews, we’re happy to announce the release of the PowerShell 7 Release Candidate (RC). Whether you’ve been running PowerShell Core since our first alpha releases or you’ve been clinging to Windows PowerShell for backwards compatibility, 7.0 delivers a host of improvements to make your life better.

Traditionally, Windows 10 and Windows Server have always included a set of .NET native binaries that were pre-compiled using the Native Image Generator tool (Ngen.exe).
