MES.Inside.Contracts 0.4.0-preview.5 Mayer EDV Services README.md https://inside.mes.wien/ Versioned telemetry event and ingestion contracts shared by all MES Inside clients. Preview 5 adds atomic cross-application runtime snapshots for ASP.NET Core, WebForms, Windows services, workers, console and desktop applications; request heap and GC diagnostics; bounded page tracing; installation-specific HMAC correlation; Web.config API-key fallback; and numeric properties for measured functions. It retains durable bounded spooling, hierarchical traces and stable installation identity. Requires a server upgraded for the RuntimeSnapshots contract. Not yet a stable API.
