v0.57.0

Added

• Add fsharp/addExistingFile LSP command (Thanks @MangelMaxime!)
• Support for .NET SDK 6.0.400 and 7.0.100
  • Primary change was updating the Ionide.ProjInfo dependency

Changed

• Improvements/Fixes for unused declarations (thanks @Booksbaum!)
  • Detect more cases when values are unused
  • Fixes for associated codefix to remove or ignore the value
• Support removing files that are outside the fsproj directory (thanks @MangelMaxime!)
• Reverted back to full-text synchronization from incremental sync
  • This didn't play well with the debounced checking that we do, so we need to rethink the interaction between the features
