Optimizely CMS 13 should run on .NET 11.
Optimizely CMS 13 should support running on .NET 11.
Today, CMS 13 officially supports .NET 10, but attempting to run it on .NET 11 currently fails because of a breaking runtime change that results in a System.MissingMethodException.
I have documented the current issue, including a workaround, here:
https://www.gulla.net/en/blog/upgrading-optimizely-cms-13-from-dotnet10-to-dotnet11/
The request is not necessarily to make .NET 11 the recommended production runtime, but to make CMS 13 compatible with it where this can be done without affecting .NET 10 support.
