Tools for parsing and exploring PRI (Package Resource Index) files

This sample application allows to open and browse the contents of PRI files. It is also possible to export individual resources.

The application leverages the XbfAnalyzer (originally by misenhower) to provide on-the-fly decompilation of XBF2 resources back to XAML.

This project implements a PRI file reader in C# for low-level access to pretty much all structures in the PRI file format. Only file reading, not writing, is supported at the moment.

You can use the following code to open a PRI file and print the names of all resource map items:

using (FileStream stream = File.OpenRead(path))
{
    PriFile priFile = PriFile.Parse(stream);

    ResourceMapSection resourceMapSection = priFile.GetSectionByRef(priFile.PriDescriptorSection.PrimaryResourceMapSection.Value);

    foreach (CandidateSet candidateSet in resourceMapSection.CandidateSets.Values)
    {
        ResourceMapItem resourceMapItem = priFile.GetResourceMapItemByRef(candidateSet.ResourceMapItem);

        Console.WriteLine(resourceMapItem.FullName);
    }
}

For more sample code, see the PriInfo project.

Package Resource Index File Format.md contains a reasonably complete (but unofficial) description of data structures in the PRI file format.

XBF2 decompilation code is originally based on the implementation by misenhower.
