Document Library for UWP is a collection of classes that provide a cross-platform framework for working with various document types. The library is used internally by a number of ComponentOne components, such as FlexReport and can be used directly to access PDF documents. C1Document enables the FlexViewer control to load and view the supported document formats, such as FlexReport, and PDF. The library also provides programmatic access to exporting, printing, and other operations such as text search.
