Performance talks on #powershell will tell you to avoid += on arrays, because it copies the array to a new one every single time. But the reality is much worse. 🧵1/17
Have something cool you've made with #PowerShell? Sign up to show it off at the #PowerShell/#OpenSSH Community Call on May 16th, github.com/orgs/PowerShel…
Don't forget that our monthly aka.ms/pscommunitycall is today at our normal time!
Just finalised what could be my largest contribution to #PowerShell .NET named arguments support github.com/PowerShell/Pow…. Big thanks to @SeeminglyScienc for all this help. This was a fun exercise in learning about the pwsh parser/ast, compiler, and binder all in one!
Because of the progression of his brain cancer, Sean had a minimal details. He's now had a friend significantly expand the details in the writeup of his family's story. I had no idea things had gotten this bad. 🙁 Please share for reach. Consider donating if you can.

#PowerShell 7.4 GA is out! Read more about it here: devblogs.microsoft.com/powershell/pow…. Thanks to the team and community for making this possible!
Automatically convert lengthy multi-parameter #PowerShell commands to use splatting mikefrobbins.com/2023/10/19/aut… <<-- New blog article
PSResourceGet is generally available! Thanks to everyone who contributed to this effort! devblogs.microsoft.com/powershell/psr…
PSResourceGet (aka PSGet3.0) is GA. The culmination of a years-long huge amount of implementation and compatibility testing. Congrats to @sydneysmithreal and the entire underlying team. devblogs.microsoft.com/powershell/psr…
Would anyone have any clue why calling CreateProcess with CREATE_NEW_CONSOLE would fail with 5 (Access Denied). I've been unable to replicate it myself but I know for sure that on a Server 2016/2019 host through WinRM it will fail with this flag but the same args work without it.
We will be having a LIVE PUBLIC BUG BASH July 27th 9am-10am pdt (Seattle time) for PSResourceGet...more info and a Teams join link to follow🐛 🥳 (there will be async instructions provided afterwards for those who aren't able to join live)
Just pushed a prerelease version of the #PowerShell #Pester @code extension. This adds support for Pester 5.5, fixes bugs with having a large amount of test files, and adds a lot more logging to see whats going on. Give it a try and file any issues! marketplace.visualstudio.com/items?itemName…
Just created Yet Another YAML #PowerShell module and published it to the PSGallery github.com/jborean93/Powe…. It's 7.2+ only as it uses an AssemblyLoadContext to avoid DLL hell. Some nice features in there including YAML 1.2 and custom parser/emitting support.
Turns out there is no TOML parser/writer for PowerShell so I wrote a module wrapping Tomlyn called PSToml github.com/jborean93/PSTo…. Currently online in the PSGallery! Needs PowerShell 7.2+ due to its use of Assembly Load Contexts.
🚨New PSReadLine Beta Just Dropped 🚨 Download 2.3.1.beta1 from the Gallery and read more about the new features from this blog post: devblogs.microsoft.com/powershell/psr…
This morning, members of my team focusing on #PowerShell discussed how we can provide more impact to the community on our Monday Community Day. So several things came out of this:
Anyone know what the IMAGELOG resource property is on Windows? I'm struggling to find any definitive info on it.
First RFC I've written for #PowerShell github.com/PowerShell/Pow…. It's to try and improve the UX when it comes to custom remoting providers with cmdlets like Invoke-Command.
Don't know if github.com/CarloToso is on Twitter, but so many contributions from Carlo coming in PS7.4-preview.2!
v0.2.0 is now live on the PowerShell gallery powershellgallery.com/packages/Ctype…. Happy PInvoking.
