A new article shows how you can use the code under the hood of PowerTools for OpenXML  in a .NET application. PowerTools provided rich PowerShell functionality for simplifying scenarios such as joining documents with a single command. This article, with included code shows, will show you how you can do the same with a single .NET method call instead of from a PowerShell script. The article takes the functionality of an earlier article that does some interesting document assembly using PowerShell, and replicates this in C# as a Windows application.
