  • Show target frameworks next to the assembly version in the tree-view
  • Using the middle mouse button to click on tree nodes and links will open the decompilation result in a new tab.
  • "Select PDB" context menu: allows to change the PDB file resolved by ILSpy or pick one from a different location
