I’m happy to announce Marvin.Cache.Headers 4.0 was just released. This release retargets Marvin.Cache.Headers to .NET Standard 2.0. Next to bugfixes it also includes one breaking change: action-level attributes now override controller-level attributes instead of the other way around (as it should’ve been al along). This release has also been tested with the current prerelease version of ASP.NET Core 3.0 (preview 8).
You can find it over on NuGet. If you notice any issues or want to contribute, check the issue list on GitHub.
Happy coding!
