> .NET Core ( dotnet at the CLI ) has replaced .NET Framework and ( by implication ) has replaced Mono as well. That is what I think the post above is trying to say.
dotnet build (from the modern .NET CLI) can compile .NET SDK projects that target legacy Framework versions. A csproj with a .NET.Sdk reference can use a TargetFramework of net48 or lower.
dotnet build times are an order of magnitude faster than Mono’s msbuild command, and migrated projects also receive the recent dotnet toolchain improvements (like automatic nuget restore, among many others).
Unity projects sometimes use dotnet's csc, even when the compiled libraries are executed with the Mono .NET (Framework!) 4.x runtime.
