  - Exit code: not provided in the log (non-zero error)

- Failing command/step
  - [build 5/8] COPY ET.sln ./

- Missing packages or files mentioned
  - File not found: /ET.sln (ET.sln not found in build context)

- Version mismatch info
  - Base image appears to be Ubuntu 22.04 (ubuntu:22.04)
  - .NET components referenced: dotnet-runtime-8.0 and dotnet-sdk-8.0
  - No explicit version mismatch indicated in the log; the failure is due to the missing ET.sln file

Suggested quick fix
- Ensure ET.sln exists in the build context (and not ignored by .dockerignore) or adjust the COPY path to the correct location.

Actionable gist of the tool output:

- Context: JetBrains/Rider style settings dump (XAML ResourceDictionary) for Code Editing, IntelliSense, Code Style, Naming, Environment, etc.

- Notable file paths and versionish info:
  - Java/JDK: C:\Apps\Java\jdk1.8.0_131
  - Roslyn CSI (C# interactive): C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\15.0\Bin\Roslyn\csi.exe
  - ReSharper/Rider sessions store: C:\Users\USER-PC\AppData\Local\JetBrains\Shared\vAny\Sessions
  - Xamarin/Build: same Java JDK path (C:\Apps\Java\jdk1.8.0_131) listed under Build/Xamarin/JavaDevelopmentKitPath
  - Snapshot store: C:\Users\USER-PC\AppData\Local\JetBrains\Shared\vAny\Sessions
  - Theme: Dark (CurrentTheme)

- Key feature toggles (highlights):
  - IntelliSense/Code Completion: AutoCompleteBasicCompletion True; CacheImportCompletion True; CompletionFilters PersistFilterState True
  - IntelliSense non-completing chars: NonCompletingCharacters <>;
  - UpgradedFromVSSettings True
  - Localization: DontAnalyseVerbatimStrings False
  - Typing Assist: VirtualSpaceOnEnter False
  - OpenDocument after modification: True
  - Inlay hints: ShowInlayHints False (Environment/InlayHints shows various Never/False for parameter hints)
  - NuGet: GlobalEnabled True; IncludePrerelease False
  - Theme: Dark

- Code style and cleanup (Unity profile embedded XML):
  - Unity profile in /Default/CodeStyle/CodeCleanup/Profiles
  - Unity cleanup flags: CSArrangeThisQualifier True; CSRemoveCodeRedundancies True; CSShortenReferences True; CSReformatCode True; RemoveCodeRedundancies True; Many arrangement settings (ArrangeBraces, ArrangeAttributes, etc.) True
  - Auto-detected naming rules: multiple entries with Style="AaBb" or "aaBb"; several prefix/suffix policies
  - EventHandlerPatternLong for C# and VB: "$object$_On$event$"

- Bracing/formatting preferences:
  - BRACES_FOR_FOR/FOREACH/IFELSE/WITH/WHILE: Required
  - ForceAttributeStyle: JOIN
  - Wrap and alignment settings (WRAP_IF_LONG, WRAP_LIMIT 150, etc.)

- Naming and patterns:
  - AutoDetectedNamingRules for Constants, EnumMember, Event, Interfaces, Locals, Method, Parameters, TypeParameters, TypesAndNamespaces (styles AaBb/aaBb)
  - Some explicit naming rules for user-defined/Predefined rules

- Migration and housekeeping flags:
  - SettingsMigration IsMigratorApplied: multiple migrations set True (numerous JetBrains migration entries)
  - Housekeeping: extensive keybinding/shortcut mappings for VS actions are present and set to True

- Misc:
  - Inspection severities: many entries set to DO_NOT_SHOW
  - ProcessingInstruction/Xml formatting and various language-specific format settings present

If you need, I can extract a focused subset (e.g., all file paths with their values, or all True/False toggles) or convert this into a config-change plan.
