Successfully built the project and fixed all compilation issues! Here's what was resolved: Major Issues Fixed:
The project now builds successfully with no compilation errors. All HttpClient service changes are working correctly and tests are properly updated for the new dependency injection patterns. Fixed in commit c8ea353. Warning Firewall rules blocked me from connecting to one or more addressesI tried to connect to the following addresses, but was blocked by firewall rules:

Pull Request Overview
This PR implements a centralized HttpClient service design to replace problematic direct HttpClient instantiation patterns throughout the Azure MCP codebase. The implementation provides injectable HttpClient management with global configuration control and enterprise proxy support through environment variables.
Key changes include:
- Introduction of
IHttpClientServiceinterface andHttpClientServiceimplementation with proxy configuration - Replacement of static/per-request HttpClient instances in MonitorHealthModelService, KustoClient, and FoundryService
- Comprehensive test coverage and documentation for the new service architecture

This PR implements a centralized HttpClient service design that provides injectable HttpClient management with global configuration control and proxy support.
Problem
Multiple commands throughout Azure MCP were creating HttpClient instances directly using problematic patterns:
This led to resource management issues, inconsistent configuration, and no centralized proxy support for enterprise environments.
Solution
Core Infrastructure
IHttpClientService: Injectable interface for centralized HttpClient managementHttpClientService: Implementation with proxy configuration and resource managementHttpClientOptions: Configuration class supporting environment variablesProxy Support
The service automatically reads and applies standard proxy environment variables:
ALL_PROXY: Global proxy for all protocolsHTTP_PROXY: Proxy for HTTP requestsHTTPS_PROXY: Proxy for HTTPS requestsNO_PROXY: Comma-separated bypass listUpdated Services
Example Usage
Benefits
Testing
Added comprehensive unit tests covering:
Fixes #407.
