Generate a complete MCP server project in C# with tools, prompts, and proper configuration

# Generate C# MCP Server

Create a complete Model Context Protocol (MCP) server in C# with the following specifications:

## Requirements

1. **Project Structure**: Create a new C# console application with proper directory structure
2. **NuGet Packages**: Include ModelContextProtocol (prerelease) and Microsoft.Extensions.Hosting
3. **Logging Configuration**: Configure all logs to stderr to avoid interfering with stdio transport
4. **Server Setup**: Use the Host builder pattern with proper DI configuration
5. **Tools**: Create at least one useful tool with proper attributes and descriptions
6. **Error Handling**: Include proper error handling and validation

## Implementation Details

### Basic Project Setup
- Use .NET 8.0 or later
- Create a console application
- Add necessary NuGet packages with --prerelease flag
- Configure logging to stderr

### Server Configuration
- Use `Host.CreateApplicationBuilder` for DI and lifecycle management
- Configure `AddMcpServer()` with stdio transport
- Use `WithToolsFromAssembly()` for automatic tool discovery
