Declarative caching for .NET: [Cache] attributes compiled by a source generator, tag invalidation, and an in-memory cache with optional Redis or SQL Server as a distributed cache

OpenTelemetry instrumentation for MethodCache: traces and metrics for cache operations

Redis as MethodCache's distributed cache, with a pub/sub backplane that keeps every instance's in-memory cache in sync

SQL Server as MethodCache's distributed cache, with a polling backplane that keeps every instance's in-memory cache in sync

ASP.NET Core admin endpoints and health check for MethodCache: inspect statistics and entries, invalidate tags and clear the cache at runtime

HTTP caching for HttpClient: ETag and Last-Modified revalidation, Cache-Control and Vary, as in RFC 9111

MessagePack serialization for MethodCache: compact binary values in Redis and SQL Server instead of the default System.Text.Json
