Foundations & compatibility
Evidence basis: source-verified at the pinned commit. Claims on this page were checked by reading the CNA source at commit 3b43bd86; unless a sentence says otherwise, nothing here was built or executed.
What CNA is, how it relates to XNA and to the sibling projects, the vocabulary the rest of the site relies on, the CNAEXT extension policy, and the difference between representing an XNA API, matching its behaviour and proving that it matches.
Pages in this group
- CNA and XNA 4.0: what the compatibility promise covers — What CNA translates and cannot load, which reference settles a disputed XNA question, what CNA deliberately is not at snapshot 3b43bd86, and its Ms-PL licence and FNA provenance.
- Compatibility levels and the evidence vector — The distinct levels of XNA compatibility CNA keeps apart, the evidence vocabulary used across the site, what each renderer class can prove, and how to state a verification claim.
- The CNA ecosystem: siblings, references and consumers — Which repositories CNA builds against, audits against and is consumed by, when CMake needs each sibling, where each sibling draws its boundary, and which revision each statement refers to.
- From C# to C++: CNA's translation conventions — How CNA represents C# XNA concepts in C++ so that code stays diffable against the reference: names, properties, aliases, events, interfaces, disposal, visibility, layout and the porting checklist.
