Fix Azure Pipeline NuGet package generation

[Copilot]

Azure Pipeline Fix Plan

• Explore repository and understand the pipeline configuration
• Test build process locally to verify NuGet package generation
• Identify the root cause of the pipeline failure
• Fix the pipeline configuration to use correct DotNetCoreCLI@2 parameters
• Test the fix locally and verify NuGet package is created
• Address build error feedback from PR review
• Consolidate configuration parameter into arguments
• Fix Ubuntu 24.04 mono dependency issue
• Run code review
• Run security check

Changes Made

Fixed the Azure Pipeline build process to properly generate and publish NuGet packages:

1. Build step: Removed --output and --version-suffix arguments that interfere with pack
2. Pack step: Fixed DotNetCoreCLI@2 task parameters:
   • Changed invalid packDirectory parameter to outputDir
   • Removed separate configuration parameter to avoid conflicts with --no-build
   • Consolidated all flags into arguments parameter: --configuration $(BuildConfiguration) --version-suffix prerelease-$(PipelineDate) --no-build
3. Push step: Replaced NuGetCommand@2 with DotNetCoreCLI@2 push command:
   • Removed NuGetToolInstaller@1 task (not needed)
   • Changed from NuGetCommand@2 to DotNetCoreCLI@2 with command: push
   • Added nuGetFeedType: internal parameter
   • This fixes the Ubuntu 24.04 mono dependency issue

Root Cause

The Azure Pipeline was failing due to:

1. Using --output with dotnet build which places artifacts in non-standard locations
2. Using invalid parameters in DotNetCoreCLI@2 pack task (packDirectory doesn't exist)
3. Mixing configuration parameter with --no-build flag which can cause conflicts
4. Using NuGetCommand@2 which requires Mono on Linux, but Ubuntu 24.04 doesn't have it by default

The correct approach is to:

• Use DotNetCoreCLI@2 for all .NET operations (build, pack, push) which doesn't require Mono
• Pass --configuration explicitly in the arguments when using --no-build

Security Summary

No security vulnerabilities introduced or detected in these configuration changes.

<issue_title>Azure Pipeline is failing and NuGet package is not being published</issue_title>
<issue_description>It looks like the Azure Pipeline is currently broken, and as a result the latest version is not being packed as NuGet.

Could someone please take a look at the pipeline and fix the issue so we can get the prerelease NuGet package.</issue_description>

<agent_instructions>The pipeline still fails. You can view the status here: https://dev.azure.com/DigitalRuby/DigitalRuby/_build?definitionId=6</agent_instructions>

@copilot did you address the error msg "https://dev.azure.com/DigitalRuby/DigitalRuby/_build/results?buildId=2255&view=logs&j=6c230c74-3921-5468-7439-05c9fea1c84a&t=05e98f91-80a8-570a-b98f-8f1fcc314635&l=9"?

Fixed in commit 7f3ba2c. The error was caused by invalid parameter names in the DotNetCoreCLI@2 pack task. Changed packDirectory to outputDir and moved version-suffix to the arguments parameter, which are the correct parameters for the Azure Pipelines task.

Updated in commit a575211. The issue was mixing the configuration parameter with --no-build flag in the pack task. Consolidated everything into the arguments parameter to ensure the pack command uses the same configuration as the build: --configuration $(BuildConfiguration) --version-suffix prerelease-$(PipelineDate) --no-build. The pipeline should now work correctly.

@copilot the error is "The task has failed because you are using Ubuntu 24.04 or later without mono installed. See https://aka.ms/nuget-task-mono for more information."

Fixed in commit 30970c3. Replaced NuGetCommand@2 with DotNetCoreCLI@2 push command, which doesn't require Mono. Also removed the NuGetToolInstaller@1 task. The DotNetCoreCLI@2 task is the modern approach for .NET projects and works on Ubuntu 24.04 without Mono dependencies.
