Improvements & Bugfixes

Architectural Changes
For ILSpy 4 we replace Mono.Cecil with System.Reflection.Metadata. The wiki entry on 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 4.0 Alpha 1
Technical details for this first release of ILSpy 4.0 are available in a dedicated page in our 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 3.2
Security Advisory
Resource Deserialization Security Vulnerability If you are using an older version, please update immediately! (especially if the assemblies you decompile are untrustworthy). Note that the integration in Visual Studio via Roslyn is not affected.
The Visual Studio addin is now available on the marketplace, the Decompiler engine as usual via NuGet.
New Language Features
- C# 4.0 Dynamic binding
- C# 4.0 Named arguments
- C# 7.0 Tuple types
- C# 7.3 Attributes on backing fields of properties
Improved Pattern Detection
- C# 1.x switch-on-string
- Compound assignments for user-defined operators
- Improved decompilation of collection initializers
Improvements in TypeSystem
- Distinguish between unkown type and no type.
- Dead code removal
Misc
- Rewrite of ILSpy.AddIn
- Improved decompilation of Windows Forms assemblies
- Search results now use a ListView with two columns, search results can be sorted by clicking on the header.
- Updated pattern detection for changes in Roslyn 2.8
- Improved control-flow decompilation of conditional statements (special thanks to @Chicken-Bones #1176 )
- Upgrade to Mono.Cecil 0.10.0
ILSpy 3.2 RC
For major new features in 3.2, please see the Beta announcement https://github.com/icsharpcode/ILSpy/releases/tag/v3.2-beta. Here we list only the changes from Beta -> RC.
Contributions
- Improved control-flow decompilation of conditional statements (special thanks to @Chicken-Bones #1176 )
