Failing step
- [build 10/10] RUN dotnet publish Build.csproj -c Release -o /app/publish
- Exit code: 145
- Exact error snippet:
  The command could not be loaded, possibly because:
  * You intended to execute a .NET application:
      The application 'publish' does not exist.
  * You intended to execute a .NET SDK command:
      A compatible .NET SDK was not found.

Error specifics
- Requested SDK version: 8.0.100
- global.json file: /src/global.json
- Installed SDKs:
  8.0.419 [/usr/share/dotnet/sdk]
- Message about missing/mismatched SDK:
  Install the [8.0.100] .NET SDK or update [/src/global.json] to match an installed SDK.
- Follow-on guidance:
  Learn about SDK resolution:
  https://aka.ms/dotnet/sdk-not-found

Missing files/packages mentioned
- global.json path: /src/global.json (the file that pins the SDK)
- No matching SDK installed for 8.0.100; only 8.0.419 is present at /usr/share/dotnet/sdk

Version mismatch info
- Global.json requests SDK 8.0.100
- Installed SDK: 8.0.419

Notes
- The failure is due to SDK resolution (not having the exact requested SDK), not due to a missing publish target in the project. The container has an installed .NET SDK, but it does not satisfy the version specified by global.json. Potential fixes:
  - Install the 8.0.100 SDK, or
  - Update global.json to a version that is installed (e.g., 8.0.419).

Failing step (command):
- RUN dotnet publish Build.csproj -c Release -o /app/publish

Exact error message and exit code:
- The process did not complete successfully: exit code: 1
- NETSDK1129 errors observed (example):
  - /usr/share/dotnet/sdk/8.0.419/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.CrossTargeting.targets(31,5): error NETSDK1129: The 'Publish' target is not supported without specifying a target framework. The current project targets multiple frameworks, you must specify one of the following frameworks in order to publish: net462, netstandard2.0, netstandard2.1, net8.0 [/src/src/protobuf-net.HybridCache/protobuf-net.HybridCache.csproj]
  - /usr/share/dotnet/sdk/8.0.419/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.CrossTargeting.targets(31,5): error NETSDK1129: The 'Publish' target is not supported without specifying a target framework. The current project targets multiple frameworks, you must specify one of the following frameworks in order to publish: net462, net8.0 [/src/src/protobuf-net.Protogen/protobuf-net.Protogen.csproj]
- Additional similar NETSDK1129 messages appear for other projects (e.g., Examples, protobuf-net.Reflection, protobuf-net.Core, protobuf-net.ServiceModel, etc.) with their respective framework lists (e.g., net462, netstandard2.0, netstandard2.1, net8.0; net472, net8.0; etc.).

Missing packages or files mentioned:
- No explicit missing packages or files were reported. The log mainly shows multiple NETSDK1129 errors due to multi-target publishing.

Version mismatch / environment info:
- .NET SDK: 8.0.419 (path: /usr/share/dotnet/sdk/8.0.419)
- Root cause: Projects target multiple frameworks; the Publish target requires specifying a single target framework. The error appears across many projects with various target frameworks (net462, netstandard2.0, netstandard2.1, net8.0, net472, etc.), indicating a multi-target setup not being narrowed to one framework during publish.

- Failing step:
  - [build 11/13] RUN dotnet build Build.csproj -c Release -nologo

- Exact error message and exit code:
  - The command could not be loaded, possibly because:
    * You intended to execute a .NET application:
      The application 'build' does not exist.
    * You intended to execute a .NET SDK command:
      A compatible .NET SDK was not found.
    
    Requested SDK version: 8.0.100
    global.json file: /src/global.json
    
    Installed SDKs:
    
    Install the [8.0.100] .NET SDK or update [/src/global.json] to match an installed SDK.
    Learn about SDK resolution:
    https://aka.ms/dotnet/sdk-not-found
    8.0.419 [/usr/share/dotnet/sdk]
  - Exit code: 145

- Missing packages/files mentioned:
  - Missing/unsatisfied requirement: The global.json specifies 8.0.100, but the environment only has 8.0.419 installed.
  - global.json path: /src/global.json

- Version mismatch info:
  - Requested SDK version: 8.0.100
  - Installed SDK: 8.0.419
  - Guidance in log: Install the [8.0.100] .NET SDK or update [/src/global.json] to match an installed SDK

- Context note:
  - The error arises from SDK resolution failure when running dotnet build Build.csproj -c Release -nologo.

Summary (concise)

- Failing step:
  - [build 7/7] RUN dotnet publish assorted/BasicHttp/HttpClient/HttpClient.csproj -c Release -o /app/publish

- Exact error message and exit code:
  - MSB3644: The reference assemblies for .NETFramework,Version=v3.5 were not found. To resolve this, install the Developer Pack (SDK/Targeting Pack) for this framework version or retarget your application. You can download .NET Framework Developer Packs at https://aka.ms/msbuild/developerpacks [/src/assorted/BasicHttp/HttpClient/HttpClient.csproj]
  - Exit code: 1

- Missing packages or files mentioned:
  - Missing .NET Framework 3.5 reference assemblies (Developer Pack required) for building/publishing the project.
  - Logs also show attempted skips for missing project: Skipping project "/src/assorted/protobuf-net/protobuf-net.csproj" because it was not found (not a fatal error, but noted as missing).

- Version mismatch / context:
  - Using .NET SDK 8.0.419 (SDK path /usr/share/dotnet/sdk/8.0.419) on Ubuntu 22.04 base image.
  - The project HttpClient.csproj targets .NET Framework 3.5, which requires the .NET Framework Developer Pack; such packs are Windows-targeting and not present by default on this Linux-based image. This manifest mismatch causes the failure during publish.

- Project: MetroDto, C# class library. ProjectGuid {ED830391-FFCF-4AA4-B472-A4449BD307B6}; ProductVersion 8.0.30703; SchemaVersion 2.0; RootNamespace MetroDto; AssemblyName MetroDto; DefaultLanguage en-US; FileAlignment 512; ProjectTypeGuids {BC8A1FFA-BEE3-4634-8014-F334798102B3}; {FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}.
