That broke the net9/net10 legs at "Run Build": solution projects that target a fixed net8.0 and reference FsAutoComplete.Core (FsAutoComplete.Tests.TestExplorer, OptionAnalyzer) could no longer resolve a matching TFM once Core was narrowed to net9.0/net10.0 (NU1201). Keep the libraries multi-targeted as plain net8.0;net9.0;net10.0 so fixed-TFM consumers always find their framework. Every leg still builds with the .NET 10 SDK (the actual fix for the Paket-10-is-net9-only restore failure) and just runs `dotnet test -f ` for the framework under test.
