I need to convert an XPS file I create with my application to a PDF file, what is the best way to do so? I prefer this to be done from inside C# using a managed assembly.
Open source is preferred upon third party solutions
You can use the XpsDocument class to read the XPS files, then use a PDF library (such as Report.Net or #PDF) to export it. I used #PDF back in .NET 1.1, but not sure if it can be easily converted to .NET 2.0.
