Pull Request Overview
This PR adds Microsoft.Extensions.AI Proof of Concept (POC) implementation to TelegramSearchBot, demonstrating the feasibility of integrating Microsoft's new AI abstraction layer while maintaining backward compatibility through configuration switches and fallback mechanisms.
- Introduces OpenAIExtensionsAIService using Microsoft.Extensions.AI abstractions with automatic fallback to legacy implementation
- Adds Linux deployment support with platform-specific runtime packages and dedicated scripts
- Implements comprehensive testing framework for the new AI service integration

Using a static field for an instance property violates object-oriented principles. The static field _botName shared across all instances can lead to unexpected behavior. Consider making it an instance field or using dependency injection to manage bot name configuration.

This method logs a configuration change but doesn't actually update the configuration or trigger any logic. Either implement the configuration update functionality or remove this method if it's purely for demonstration purposes.

Using multiple reflection calls in sequence is inefficient. Consider caching the property info or using a more efficient approach to find the correct property. This reflection-heavy approach could impact performance in high-throughput scenarios.
| // Try reflection with all possible property names | |
| var embeddingProp = embedding.GetType().GetProperty("Embedding") | |
| ?? embedding.GetType().GetProperty("EmbeddingVector") | |
| ?? embedding.GetType().GetProperty("Vector") | |
| ?? embedding.GetType().GetProperty("EmbeddingData") | |
| ?? embedding.GetType().GetProperty("Data"); | |
| // Efficient reflection: cache property info in a dictionary | |
| var properties = embedding.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance); | |
| var propertyDict = properties.ToDictionary(p => p.Name, p => p); | |
| string[] possibleNames = { "Embedding", "EmbeddingVector", "Vector", "EmbeddingData", "Data" }; | |
| PropertyInfo embeddingProp = null; | |
| foreach (var name in possibleNames) | |
| { | |
| if (propertyDict.TryGetValue(name, out var prop)) | |
| { | |

This simplified implementation delegates all chat functionality to the legacy service, effectively bypassing the Microsoft.Extensions.AI integration for the core chat feature. Consider implementing at least a basic Microsoft.Extensions.AI chat implementation with fallback, as this is likely a primary use case for the POC.

| // TODO: 后续实现完整的Microsoft.Extensions.AI聊天功能 | |
| _logger.LogInformation("{ServiceName}: 聊天功能暂时使用原有服务实现", ServiceName); | |

| } | |
| // 优先使用Microsoft.Extensions.AI实现聊天功能，失败时回退到原有服务 | |

| _logger.LogInformation("{ServiceName}: 尝试使用Microsoft.Extensions.AI实现聊天功能", ServiceName); | |
| // 假设已通过依赖注入获得AIClient（或类似服务），此处为简化示例 | |
| var aiClient = _serviceProvider.GetService<AIClient>(); | |
| if (aiClient == null) | |
| { | |
| throw new InvalidOperationException("AIClient 未配置"); | |
| } | |
| // 构造请求（假设AIClient支持Chat接口，具体API根据实际情况调整） | |

| { | |
| Role = "user", | |

| }, | |
| Model = modelName | |

The error message would be more helpful if it also included the expected property types and the actual value types found. Consider adding information about what was expected and what was actually returned to aid in debugging.
| _logger.LogError("Failed to extract embedding data. Available properties: {Props}", | |
| string.Join(", ", embedding.GetType().GetProperties().Select(p => $"{p.Name}:{p.PropertyType.Name}"))); | |
| // Collect expected property names and types | |
| var expectedProps = new[] | |
| { | |
| "Embedding", "EmbeddingVector", "Vector", "EmbeddingData", "Data" | |
| }; | |
| var expectedTypes = new[] | |
| { | |
| typeof(float[]).Name, | |
| typeof(IEnumerable<float>).Name, | |
| typeof(IReadOnlyList<float>).Name | |
| }; | |
| // Collect actual value types for each property | |
| var actualValueTypes = embedding.GetType().GetProperties() | |
| .Select(p => | |
| { | |
| object value = null; | |
| try { value = p.GetValue(embedding); } catch { } | |
| var valueType = value?.GetType().Name ?? "null"; | |
| return $"{p.Name}:{p.PropertyType.Name} (value type: {valueType})"; | |
| }); | |
| _logger.LogError( | |
| "Failed to extract embedding data. Expected property names: {ExpectedProps}, expected types: {ExpectedTypes}. Available properties: {Props}", | |
| string.Join(", ", expectedProps), | |
| string.Join(", ", expectedTypes), | |
| string.Join(", ", actualValueTypes) | |
| ); |
