This PR addresses the requirement to generate complete documentation for all methods on the .NET System.IO.Directory class using the Microsoft Learn MCP service.

What's Added

A comprehensive documentation file Directory_Methods_Documentation.md that covers all 40+ static methods in the System.IO.Directory class, including:

• Creation methods: CreateDirectory (2 overloads), CreateSymbolicLink, CreateTempSubdirectory
• Deletion methods: Delete (2 overloads)
• Enumeration methods: EnumerateDirectories, EnumerateFiles, EnumerateFileSystemEntries (4 overloads each)
• Array-based retrieval methods: GetDirectories, GetFiles, GetFileSystemEntries (4 overloads each)
• Time-related methods: 12 methods for getting/setting creation, access, and write times
• Directory information methods: GetCurrentDirectory, SetCurrentDirectory, GetDirectoryRoot, GetParent
• Utility methods: Move, Exists, GetLogicalDrives, ResolveLinkTarget

Documentation Features

Each method entry includes:

• Complete method signature with correct parameter types
• Detailed parameter descriptions with expected values and constraints
• Return value documentation
• Comprehensive exception information with specific conditions
• Platform-specific attributes (e.g., [UnsupportedOSPlatform("windows")])
• Usage examples and implementation notes where applicable

Data Source

All documentation content was sourced exclusively from the official Microsoft Learn documentation using the Microsoft Docs MCP service, ensuring accuracy and alignment with official .NET documentation standards.

Benefits

This documentation provides developers with:

• A single, comprehensive reference for all Directory class methods
• Detailed parameter help for proper API usage
• Exception handling guidance
• Cross-references to related classes and common I/O tasks

The documentation follows standard .NET documentation conventions and includes helpful reference tables for wildcard patterns and method comparisons.
