2016-06-05T16:01:55+00:00

Fixes, Changes and Features are listed in the [milestone 2.4 issues](https://github.com/icsharpcode/ILSpy/issues?q=milestone%3A2.4+is%3Aclosed)

ILSpy 0.76

2017-05-28T17:42:29+00:00

ILSpy 3.0-Preview1

2017-09-19T09:00:58+00:00

This is a preview release! Framework requirements: .NET 4.6.1 or higher. Language support status can be found in [issue #829](https://github.com/icsharpcode/ILSpy/issues/829), please note that this is a live issue and might have changed after this preview has been published. Notable missing feature compared to older versions: nullables. (only fully implemented features have a checkmark in the status issue). Before opening an issue ("X doesn't decompile correctly") please go check with [issue #829](https://github.com/icsharpcode/ILSpy/issues/829)! New: support for .NET Standard and .NET Core assemblies. Missing: decompile to VB. Contributions welcome because we concentrate solely on C#. Architectural changes are documented in the [wiki](https://github.com/icsharpcode/ILSpy/wiki/newdecompiler) (Note: roadmap not up to date as of this release). Important points to note (design goals): the decompiler should always create semantically correct and compilable code.

ILSpy 3.0-Preview2

2017-10-03T11:46:09+00:00

What's new compared to Preview 1? * (Partial) support for nullables, foreach, using * New: Open assembly from Nuget package * A *lot* of small-ish fixes * The VSIX is here! And it supports output from netstandard and netcore projects. * The -alpha4 Nuget package corresponds to this release.

ILSpy v3.0-beta1

2017-10-23T05:01:25+00:00

ILSpy v4.0-alpha1

2018-07-23T15:30:09+00:00

Technical details for this first release of ILSpy 4.0 are available in a dedicated page in our wiki: [SRM](https://github.com/icsharpcode/ILSpy/wiki/srm) deals at length with information that is important to addin writers, the background story and some of the performance/memory improvements you as a user of ILSpy can expect. Our goal for this version given the underlying architectual changes is as follows: "As good or better as ILSpy 3.2 in terms of decompilation quality, stability, performance and memory usage." Therefore we ask you to compare the last released production version with this Alpha 1 - we are confident that even at this early stage we match the quality in decompilation. If not, please do open an issue (sample assemblies very much appreciated!)

ILSpy 0.92

2018-07-24T09:09:27+00:00

And we want to thank all testers, who provided feedback and tested very thoroughly! # New Language Features * C# 1.0/2.0 overloaded &&/|| operators * C# 4.0 optional arguments * C# 7.1 reference assemblies: ILSpy will show a warning if you are looking at a reference assembly * C# 7.2 non-trailing named arguments * C# 7.2 stackalloc with Span * C# 7.3 stackalloc initializers # Improved Pattern Detection * Decompilation and pretty-printing of float literals (#517 -> #1350) * Object and array initializer improvements * Various smaller improvements in correctness and prettiness of the decompiled code. * Decompilation of integer literals (#1322) * Variable splitting works better with method calls (#1253) * Expression Trees: Multiple levels of nesting are now supported better * C# 6.0 string interpolation with FormattableString/IFormattable # Contributions ## Decompilation engine * Chicken-Bones: Improved block ordering in ConditionDetection (#1218) * Chicken-Bones: Improved switch and loop detection (#1258, #1295 and #1296) * ashmind: Decimal constant improvements (#1236) * Viridovics: Add cast to object for reference types in ExpressionBuilder.VisitUnboxAny (#1277) * vizv: Fix yield return for assembly compiled with Mono (#1303) * cshung: Bug fix for #1224 (#1243) ## Others * ninjaoxygen: Update UniversalAssemblyResolver to include missing .NET 3.x [Compact Framework] support (#1347) * wangzq: Add command line argument "/config:" to specify settings file (#1360) * kmatyaszek: Add show IL code to ICSharpCode.Decompiler.Console (#1285) * agametov: CWE-252 The return value of function 'Reverse' is required to be utilized. (#1305) * siriak: Code cleanup (#1363) # Improvements & Bugfixes * Added option to display all members, including compiler-generated members and getters/setters in tree view. (#747) * Added option to display metadata token in 10-based or hex format. (#628) * Reorganized option pages. (#1130) * Local functions: Code is no longer hidden if local functions are used in the code, as long as they're not decompled correctly. Note that this might still lead to compile errors, if anonymous types or lambdas are used in the local functions. * Decompilation of invalid IL * Improved decompilation of C++/CLI constructs * Improved stability of analyzers * Various smaller bugfixes # Misc * CreateCecilObjectModel: extension method to help plugin writers porting their plugins to ILSpy 4.0 * IAmbience API revived: If you want to nicely print type names or member signatures in C# style, you can now use CSharpAmbience * "Open containing folder" and "Open command line here" added to Assembly tree nodes. * Experimental PDBgen (no lambda support, no yield/async state machines; very basic C#) * New IAnalyzer API * Added IDocumentationProvider: allows providing XML doc comments from custom sources * Added IDebugInfoProvider: allows providing debug info (variable names and sequence points) # Architectural Changes For ILSpy 4 we replaced Mono.Cecil with System.Reflection.Metadata. The [wiki entry on SRM](https://github.com/icsharpcode/ILSpy/wiki/srm) deals at length with information that is important to addin writers, the background story and some of the performance/memory improvements you as a user of ILSpy can expect. Our goal for this version given the underlying architectual changes is as follows: "As good or better as ILSpy 3.2 in terms of decompilation quality, stability, performance and memory usage."

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 or newer minor release](https://dotnet.microsoft.com/en-us/download/dotnet/6.0) must be installed prior to starting ILSpy. IMPORTANT: If you don't have the .NET Desktop Runtime installed, the .NET bootstrapper (a dialog popping up when you try to run ILSpy) will link you to the .NET Runtime which supports only console apps! Please follow the above link and download the Desktop Runtime. # New Language Features * C# 11: Required members * Updated pattern detection for Roslyn 4.4.0 # Contributions * Add option to always fully qualify type names with `global::` (see #2762 by @hexafluoride) * Refresh ready to run for .NET 7 (see #2774 by @cshung) * Fix #2736: ILSpy decides to fully qualify type name when it is not necessary (see #2789 by @ElektroKill) * Fix initialization of FakeProperty with setter (see #2792 by @exyi) * Add progress reporting to PortablePdbWriter (see #2802 by @andrewcrawley) * Include assembly name in decompiled code (see #2810 by @miloush) * 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 lock statements within yield return state machines (see #2846 by @ElektroKill) * Add support for VB async state-machines (see #2853 by @ElektroKill) * Enable various passing ignored tests (see #2852 and #2854 by @ElektroKill) * Improve support for post-increment/decrement on pointers (see #2856 by @ElektroKill) # Enhancements * Various performance improvements in the type system and decompiler engine.

Also ignore embedded resources with an invalid offset, treat them as having zero byte length. * Fix #2763: Improve decompilation of switch-on-enum by preserving enum type information when inlining local variables into SwitchInstruction.Value. * PDB generation: Use row ID instead of token in AsyncDebugInfo blob. * Fix #2806: Do not use implicitly typed out variables, if argument and parameter types do not match exactly. * #2823: Introduce IType.GetDefinitionOrUnknown() to allow better detection of async state-machines involving unknown types. * Fix #2825: Missing whitespace after new() * Fix #2827: Allow users to enter search queries that match our prefixes. * `WholeProjectDecompiler`: Fix #2830: Can't decompile project with / in resource name on Windows * Fix #2831: Popup/Tooltip scaling on multi-monitor multi-DPI setups. * `WholeProjectDecompiler`: Fix #2850: Make sure that type names longer than 255 characters are handled correctly.
