Remarks
Answered from a lazily built index rather than by scanning. The scan walked every assembly and materialized every type — twice — on every call that missed the GetType(string) fast path, which measured at seconds per call in a loaded editor. Callers re-resolve while text is being typed, so each keystroke of a partial type name paid that in full and froze the editor. The index costs one scan the first time this fallback is needed at all, and nothing after; it rebuilds itself when the number of loaded assemblies changes.
WarmTypeIndex()
Builds the type-name index ahead of need. Safe to call from any thread.
Declaration
public static void WarmTypeIndex()Remarks
The index is built lazily, so without this the first lookup that misses the fast path pays the one-time build — several seconds in a large editor domain, landing on whatever keystroke happened to come first. A tool that knows type names are about to be typed calls this from a background thread when it opens; by the time the author reaches the field, lookups are dictionary hits.
