.NET WPF desktop app using iTextSharp to merge PDF files.

1. Open PdfMergeDesktop.sln in Visual Studio (any version with NuGet enabled).
2. Build with NuGet restore enabled (or install dependencies and then build).
3. Run.

I could use help writing tests for all the asynchronous functions.

This application was inspired and guided by this article on CodeProject by Igor Krupitsky.
