PowerShell 7 RC 3 Is Available With The Following Changes

Microsoft is releasing a new version of the next gen PowerShell scripting language. Interesting users can get the PowerShell 7 Release Candidate 3. It contains a number of new features and many bug fixes from both the community as well as the PowerShell team.

PowerShell is an advanced form of command prompt. It is extended with a huge set of ready-to-use cmdlets and comes with the ability to use .NET framework/C# in various scenarios. Windows includes a GUI tool, PowerShell ISE, which allows editing and debugging scripts in a useful way.

PowerShell 7 is the first command-line shell and scripting language package based on .NET Core 3.0. It can attain compatibility with 90+% of the inbox Windows PowerShell modules by leveraging changes in .NET Core 3.0 that bring back many APIs required by modules built on .NET Framework so that they work with .NET Core runtime.

Microsoft expects General Availability of PowerShell 7 in January as their first Long Term Servicing release.

Between the Release Candidate and General Availability, Microsoft will only accept critical bug fixes and no new features will be included. For that release, some Experimental Features will be considered design stable and no longer be Experimental. This means that any future design changes for those features will be considered a breaking change.

Key features of PowerShell 7

• .NET Core 3.1 (LTS)
• ForEach-Object -Parallel
• Windows compatibility wrapper
• New version notification
• New error view and Get-Error cmdlet
• Pipeline chain operators (&& and ||)
• Ternary operator (a ? b : c)
• Null assignment and coalescing operators (?? and ??=)
• Cross-platform Invoke-DscResource (experimental)
• Out-GridView, -ShowWindow and other legacy GUI cmdlets are back on Windows
