Deployment Method: Individual Install, Upgrade, & Uninstall
To install ILSpy, run the following command from the command line or from PowerShell:
To upgrade ILSpy, run the following command from the command line or from PowerShell:
To uninstall ILSpy, run the following command from the command line or from PowerShell:
Deployment Method:
This applies to both open source and commercial editions of Chocolatey.
1. Enter Your Internal Repository Url
(this should look similar to https://community.chocolatey.org/api/v2/)
2. Setup Your Environment
1. Ensure you are set for organizational deployment
Please see the organizational deployment guide
2. Get the package into your environment
Option 1: Cached Package (Unreliable, Requires Internet - Same As Community)-
Open Source or Commercial:
- Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
- You can also just download the package and push it to a repository Download
-
Open Source
-
Download the package:
Download - Follow manual internalization instructions
-
-
Package Internalizer (C4B)
-
Run: (additional options)
choco download ilspy --internalize --source=https://community.chocolatey.org/api/v2/
-
For package and dependencies run:
choco push --source="'INTERNAL REPO URL'"
- Automate package internalization
-
Run: (additional options)
3. Copy Your Script
choco upgrade ilspy -y --source="'INTERNAL REPO URL'" [other options]
See options you can pass to upgrade.
See best practices for scripting.
Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.
If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:
choco upgrade ilspy -y --source="'INTERNAL REPO URL'"
$exitCode = $LASTEXITCODE
Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
Exit 0
}
Exit $exitCode

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).
Chocolatey Pro provides runtime protection from possible malware.

ILSpy 9.x is based on .NET 8.0. All artifacts except the self-contained distribution are built framework-dependent, which means .NET 8.0.x or later must be installed prior to starting ILSpy. Note that ILSpy 9.1 also allows a later runtime via #3391.

- #2716: Add an option to allow sorting custom attributes
- #3377: Extend error information if multiple assemblies with the same (short) name are selected when creating a solution file.
- #3393: Option to turn off smooth scrolling
- #3399: Add module filename as ToolTip of AnalyzerEntityTreeNode
- #3440: Added support for evaluation-order-preserving reference type check
- #3316: Add "variable scopes" to improve naming local variables and anonymous method parameters
Contributions
- Add support for array initialization based on
RuntimeHelpers.CreateSpan<T>
(see #3380 by @ds5678) - Load resource stream outside of delegate (see #3389 by @snorrk)
- Allow ILSpy to launch, when net8.0 is not installed, but a later version (see #3391 by @nil4)
- Fix nested namespace directories (see #3449 by @ds5678)
- Fix #3402: System.NullReferenceException on right click on .NET 9 (see #3403 by @tom-englert)
- Add an option to turn off smooth scrolling (see #3405 by @tom-englert)

- Fix #3381: Make sure that selectedNode is still selected when focus is deferred in IsActive property changed handler.
- Fix #3383: more aggressively transform object initializers on structs
- Fix #3384: add special case for null-literal conversions in optional argument handling.
- Fix #3385: Allow address uses of structs in using transform, if the reference is passed to an in parameter.
- Fix #3392: uses of init-setters must use object-initializer syntax.
- Fix #3401: Multiple problems when exporting an assembly as project
- Fix #3414: Apply latest session settings before saving upon closing the main window
- Fix #3342: Wrong null check in MethodVirtualUsedByAnalyzer
- Fix #3450: Fix "Clear assembly list" not actually persistent.
