Summary of Docker build error

- Failing step: [6/7] RUN dotnet restore (Dockerfile:27)
- Exact error message and exit code (as appears in output):
  The command could not be loaded, possibly because:
  * You intended to execute a .NET application:
    The application 'restore' does not exist.
  * You intended to execute a .NET SDK command:
    A compatible .NET SDK was not found.

  Requested SDK version: 10.0.100
  8.0.419 [/usr/share/dotnet/sdk]
  global.json file: /src/global.json

  Installed SDKs:

  Install the [10.0.100] .NET SDK or update [/src/global.json] to match an installed SDK.
  Learn about SDK resolution:
  https://aka.ms/dotnet/sdk-not-found

  Exit code: 145

- Missing packages/files mentioned:
  - global.json file path: /src/global.json (used to pin the SDK)
  - The requested SDK (10.0.100) is not installed; the system only has 8.0.419 at /usr/share/dotnet/sdk
- Version mismatch info:
  - Requested SDK version: 10.0.100
  - Installed SDK: 8.0.419
  - The message indicates a mismatch between global.json requirement and available SDKs
- Context note:
  - This occurs during dotnet restore, which relies on the SDK specified in global.json; the absence of 10.0.100 causes the command to fail with exit code 145.

- Missing packages or files mentioned:
  - dotnet-sdk-10.0 could not be located in the configured apt sources after adding the Microsoft package feed.

- Version mismatch / context:
  - The Dockerfile adds the Microsoft Ubuntu 22.04 (jammy) package feed and attempts to install dotnet-sdk-10.0, but that package is not available for jammy in the configured sources. Use a supported SDK version (e.g., a currently published dotnet-sdk version such as 6.0/7.0/8.0, depending on needs) or adjust to a version present in the repository.

Summary (under 1500 chars):

- Exact error message and exit code
  - MSBUILD : error MSB1003: Specify a project or solution file. The current working directory does not contain a project or solution file.
  - Exit code: 1

- Failing command/step
  - [build 7/8] RUN dotnet restore

- Missing packages or files mentioned
  - The restore fails because the current working directory /src does not contain a project or solution file (no .csproj/.fsproj/.vbproj or .sln found).

- Version mismatch info
  - Dockerfile sets global.json with sdk version 8.0.100 and rollForward: latestFeature.
  - The actual .NET SDK installed is 8.0.419 (SDK Version: 8.0.419) and dotnet restore runs against that SDK.
  - This is consistent with the rollForward setting, but indicates a mismatch between requested (8.0.100) and installed (8.0.419) versions.

Error: file not found: README.md

Summary:
- Humanizer is a .NET library for transforming and displaying strings, enums, dates/times, timespans, numbers, and quantities in a human-friendly form. Packages: Humanizer (all languages) and Humanizer.Core (English only); language-specific packs like Humanizer.Core.fr, .es, etc.
- Install options:
  - All languages: dotnet add package Humanizer
  - English only: dotnet add package Humanizer.Core
  - Specific languages: dotnet add package Humanizer.Core.<locale> (e.g., fr, es)
- Framework targets:
  - Supported: net10.0, net8.0, net48
  - netstandard2.0 is supported as a special case for Roslyn/MSBuild tasks
  - Not officially supported: net4.6.1–net4.7.2 (though may work)
- 3.0 restore requirement:
  - Restore requires .NET SDK 9.0.200+ or VS/MSBuild with that patch
  - If using older tooling, reference Humanizer.Core and add satellite packages manually
  - Migration notes: docs/migration-v3.md
- Key capabilities (highlights):
  - Strings: Humanize, Dehumanize, Transform, Truncate
  - Enums: Humanize (with Description/DisplayAttribute precedence), DehumanizeTo
  - DateTime/DateTimeOffset: Humanize with culture, relative terms, precision strategies (PrecisionDateTimeHumanizeStrategy)
  - TimeSpan: Humanize with precision, minUnit/maxUnit, toWords, collectionSeparator, zero handling
  - Fluent Date, Number-to-words/ordinal, Inflector (Pluralize/Singularize/ToQuantity/ToWords/ToOrdinalWords), and various case converters (Titleize/Pascalize/Camelize/Underscore/Dasherize/Kebaberize)
  - ByteSize: conversion, parsing (Parse/TryParse), formatting, and Humanize with various units
  - Time units: ToSymbol, heading/clock notation, and related utilities
- ASP.NET MVC integration (sample):
  - HumanizerMetadataProvider auto-humanizes property names when no DisplayName/Display attributes exist
  - Register via: ModelMetadataProviders.Current = new HumanizerMetadataProvider();
  - Example shows replacing explicit Display attributes with automatic humanized labels
- Additional notes:
  - There are extensive docs and migration guidance; see docs/migration-v3.md
  - For practical usage, see code samples and the various public API methods described above
  - The library also offers collections formatting, age representation (ToAge), and multiple localization options

  - Context: The build produced binaries under /src/src/Humanizer/bin/Release/net10.0 (e.g., Humanizer.dll), not under /src/bin/Release/net10.0, which the COPY attempts to use.

- Version mismatch / other version info
  - dotnet install: Installed version is 10.0.100 (SDK Version: 10.0 as shown during restore/build)
  - Actual built outputs location: /src/src/Humanizer/bin/Release/net10.0 (observed in build logs)
  - The COPY path (/src/bin/Release/net10.0) does not exist; the artifacts are under /src/src/Humanizer/bin/Release/net10.0, indicating a path mismatch rather than a software version mismatch.

Notes:
- The build itself completed successfully up to the copy step; the failure is caused by attempting to copy from a non-existent path.
- To fix, align the COPY source with where dotnet build actually places artifacts (e.g., /src/src/Humanizer/bin/Release/net10.0) or adjust the build output directory in the Dockerfile.
