Edit - I have changed the title of this blog series from AngularJS GUIs with PowerShell to just PowerShell GUI with HTML. I will make a second series though covering AngularJS, how and why you should use it for making PowerShell GUIs but I figured that it needed to be split out.
I am going to cover in the next few blog posts a method I have developed for developing user interfaces for PowerShell scripts using HTML. This is not an HTA. This is all built from within PowerShell.
