Installing with Dependencies

Packages often require other packages (dependencies):

Automatic Dependency Resolution

The NuGet manager automatically:

• Identifies required dependencies
• Downloads all dependencies
• Installs them in the correct order
• Resolves version conflicts

Viewing Dependencies

Before installing, expand the Dependencies section to see:

• Required packages
• Minimum versions
• Framework requirements

Post-Installation

After installation:

• The package is available for use in code
• Add using statements for the package namespaces
• IntelliSense will show types from the package
• Build the project to restore and verify

Troubleshooting

Installation Failed

If installation fails:

1. Check the Output panel for error details
2. Verify internet connectivity
3. Ensure sufficient disk space
4. Check for package source issues
5. Verify project file permissions

Version Conflicts

If you encounter version conflicts:

1. Review the error message for conflicting packages
2. Update or downgrade conflicting packages
3. Use package consolidation features
4. Consider using binding redirects (for .NET Framework)

Package Not Found During Restore

If the package isn’t restored after installation:

1. Try manual package restore
2. Check nuget.config for source configuration
3. Verify package exists in the configured sources
4. Clear NuGet cache and retry
