ILSpy 8.0


Recommended Posts

ILSpy 8 is based on .NET 6.0 compared to .NET Framework 4.7.2 for the previous generations of ILSpy. All artifacts except the self-contained distribution are built framework-dependent, which means .NET 6.0.2+ must be installed prior to starting ILSpy.

Note - none of the following lists are exhaustive except of course the first one:

New Language Features

  • C# 10: record structs
  • C# 11: Required members
  • C# 11: ref fields
  • C# 10: Support DefaultInterpolatedStringHandler
  • Output attributes on lambda expressions
  • Updated pattern detection for Roslyn 4.4.0


  • More themes - Light/Dark are the original ones, R# & VS Code added (see #2906 and #2931 by @ltrzesniewski)
  • Improve selected text highlighting (see #2938 by @Konctantin)

  • Add option to always fully qualify type names with global:: (see #2762 by @hexafluoride)
  • Fix #2736: ILSpy decides to fully qualify type name when it is not necessary (see #2789 by @ElektroKill)
  • Add progress reporting to PortablePdbWriter (see #2802 by @andrewcrawley)
  • Add IEntityProcessor to ReflectionDisassembler (see #2835 by @tom-englert)
  • Fix dynamic type index calculation in ApplyAttributeTypeVisitor (see #2840 by @ElektroKill)
  • Add support for another using pattern (see #2841 by @ElektroKill)
  • Fix debug assertion regarding using directives (see #2843 by @ElektroKill)
  • Add support for VB cached delegate initialization (see #2844 by @ElektroKill)
  • Add support for VB auto events (see #2845 by @ElektroKill)

  • Add support for Visual Basic Yield Return state machine decompilation (see #2874 by @ElektroKill)
  • Fix ResXResourceWriter support for MemoryStream resource element (see #2895 by @ElektroKill)
  • Use .interfaceimpl type syntax (see #2903 by @ltrzesniewski)
  • Fix empty parameter names in delegate declarations (see #2912 by @ElektroKill)
  • Support disassembling ReadyToRun binaries compiled using composite mode (see #2944 by @cshung)
  • Make return duplication in ControlFlowSimplification less aggressive (see #2972 by @ElektroKill)
