“error CS0433: The type 'CodeBinaryOperatorType' exists in both 'System.CodeDom and 'System" compilation errors are thrown when opening a specific project

Package: Visual Scripting

-

Reproduction steps:
1. Open the attached “ASDQWE” project
2. Observe the Console Window

Expected results: There are no compilation errors
Actual result: 9 “error CS0433: The type 'CodeBinaryOperatorType' exists in both 'System.CodeDom, Version=7.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' and 'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'“ compilation errors are visible

Reproducible with: 2022.3.23f1, 2023.2.17f1, 6000.0.0b14
Could not test with: 2021.3.37f1 (Multiple “Multiple precompiled assemblies with the same name Grpc.Net.Client.dll included on the current platform” compilation errors)

Reproducible on: MacOS Sonoma 14.3.1 (Intel), Windows 11 (user’s)
Not reproducible on: No other environment tested

Notes:
- Clearing the Library folder does not remove the errors
- Does not reproduce on a blank project with the same Visual Scripting package version
- Removing the “Assets/Packages/System.Codedom.7.0.0” folder prevents these errors

  1. Resolution Note:

    This issue is being caused by a second version of the System.CodeDom assembly being installed by NuGetForUnity that causes compilation errors in Visual Scripting.

    You can get around this issue by

    * Exiting Safe Mode
    * Open the NuGet For Unity window
    * Open the "Installed" tab
    * Expand "Implicitely installed packages"
    * Search for "System.CodeDom"
    * click "Uninstall"

    Visual Scripting should now compile as expected
