Well.. have you ever got a request for help with creating multiple word documents based on dynamic data? Maybe you want to create some simple Invoice or send a new agreement to all employees based on their AD data… well now you can. While this method was available for long time (and I've utilized it for many of my apps in C# / .NET) it is now possible to do in PowerShell. No compilation, no exe, should work on any newer Windows system (.NET Core is still not supported by module). Keep in mind that this is still work in progress…
Some of those commands are not yet finished and some are going to evolve. Some will get new features, some will be deprecated (or not really needed).
