@bevanjkay Hi. Won't this break dotnet@9 alias as it will be installing .Net 10 instead of 9? I think it will be better to introduce new formula dotnet@9 in this PR which essentially be a copy of dotnet.rb from the current main branch. So, after PR is merged it will be possible to install both v10 and v9 of .Net.
