As you know, the PowerShell team just released the new PowerShell version called PowerShell 7. PowerShell 7 will brings a couple of new features and enhancements not only for users who used PowerShell Core 6 but also for people who are currently using Windows PowerShell 5.0. I want to quickly give you an overview of what’s new in PowerShell 7.
New feature enhancements – What’s new in PowerShell 7
There are many enhancements in PowerShell 7 to make it the best PowerShell version yet. It is almost impossible to list all of them in one single blog post, so I will focus on the once, which are the most important once for me.
Out-GridView, -ShowWindow and other GUI cmdlets are back on Windows
With .NET Core 3 brining back WPF support on Windows, the PowerShell team was able to bring back some of the popular graphical tools and cmdlets like Out-Gridview, Show-Command, and the Get-Help -ShowWindow.
Since I started using PowerShell and get into working with objects, ForEach-Object was one of the most critical cmdlets. By adding the -Parallel parameter to the ForEach-Object cmdlet, you can execute a scriptblock in parallel, similar to the option we had with PSWorkflow. With that performance can get so much better if you are working with a broad set of objects. You can also optionally set the maximum threads, which will be used in parallel (the default thread count is set to 5) with the -ThrottleLimit parameter.
