✅ Fixed NuGet Package Source Switching Bug

Todo List:

• Read CLAUDE.md for repo context and setup
• Examine current NuGet package source switching implementation
• Identify the bug causing it to always use nuget.org
• Create backend API to get/set NuGet sources
• Add source selection UI in frontend NuGet dialog
• Update backend download logic to use selected source
• Update frontend to use selected source for search/metadata
• Test the fix
• Run build/lint commands as needed
• Commit and push changes

🎯 Problem Fixed

The NuGet package source switching was broken in both frontend and backend:

Frontend Issues (Fixed):

• ❌ Hardcoded nuget.org endpoints in nugetManager.js
• ❌ No UI for source selection
• ✅ Added dynamic source endpoints that update based on selection
• ✅ Added source dropdown in NuGet dialog

Backend Issues (Fixed):

• ❌ Hardcoded https://packages.nuget.org/api/v2/package/ in download logic
• ❌ Completely ignored NuGet.config sources
• ✅ Created NugetSourceManager to read from NuGet.config
• ✅ Added /completion/nugetSources and /completion/setNugetSource APIs
• ✅ Updated download logic to use selected source

🚀 Implementation Details

New Files:

• MonacoRoslynCompletionProvider/NugetHelper/NugetSourceManager.cs - Manages NuGet source configuration

Backend Changes:

• Added API endpoints for getting/setting NuGet sources
• Updated DownloadNugetPackages.cs to use selected source
• Reads sources from NuGet.config file

Frontend Changes:

• Added source selector dropdown in NuGet package manager
• Dynamic endpoint updating based on selected source
• Cache clearing when switching sources
• User notifications for source changes

🌏 Supported Sources

The fix now properly supports all sources from NuGet.config:

• nuget: nuget.org (official)
• huaweicloud: 华为云镜像源 (Huawei Cloud Mirror)
• azure: Azure 中国镜像源 (Azure China Mirror)

🔍 How It Works

1. Backend: NugetSourceManager reads NuGet.config and maps V3 index URLs to V2 package/search endpoints
2. Frontend: Source dropdown loads available sources via /completion/nugetSources
3. Source Switch: User selects source → frontend calls /completion/setNugetSource → backend updates current source
4. Package Operations: Search, metadata, and downloads now use the selected source instead of hardcoded nuget.org
