Monogame currently recommends 9.0. Shouldn't we be using that?

Monogame recommends .NET 9.0 over 10.0.

dotnet 9 support will be dropped by Microsoft on November 10, 2026 see: https://dotnet.microsoft.com/en-us/platform/support/policy/dotnet-core.

seemingly dotnet 10 is also supported for monogame 3.8.4.1 at least.
I'm pretty sure that monogame would also have to be updated to support higher dotnet versions, currently this template is on monogame version 3.8.1.303, newest is 3.8.4. though i cannot find anything to support this idea

they'll probably end up using dotnet 10 as it is the newest LTS version of dotnet, though they didn't make it the main target b/c it released in november of 2025

Wow then, okay. Not sure why Monogame still reccomends 9.0 then.
