+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Best Practices
+
+When working with this codebase, always follow modern .NET and C# best practices:
+
+- Use latest C# language features (records, pattern matching, nullable reference types, file-scoped namespaces)
+- Follow .NET naming conventions and coding standards
+- Leverage modern async/await patterns where applicable
+- Use `System.Text.Json` for JSON serialization
+- Prefer `Span<T>` and `Memory<T>` for performance-critical code
+- Use collection expressions and LINQ for data manipulation
+- Apply proper error handling with exceptions and Result patterns
+- Write clean, readable code with meaningful variable names
+- Use nullable reference types and enable all relevant compiler warnings
+
+## Commands
+
+### Build
+```bash
+dotnet build
+```
+
+### Test
+```bash
+dotnet test --no-restore
+```
+
+### Run a single test
+```bash
+dotnet test --filter "FullyQualifiedName~TwoSumTest"
+```
+
+### Run console application
+```bash
+cd ./LeetCode
+dotnet run
+
+# Run specific commands
+dotnet run benchmark LRUCache --csharp
+dotnet run info MergeTwoLists
+dotnet run list
+```
+
+## Architecture
+
+This is a LeetCode problem solutions repository with benchmarking capabilities, structured as follows:
+
+### Three main projects:
+1. **LeetCode.CSharp** - C# implementations of LeetCode problems with xUnit tests and BenchmarkDotNet benchmarks
+2. **LeetCode.FSharp** - F# implementations of selected problems
+3. **LeetCode** - Console application for running benchmarks and viewing problem information
+
+### Key architectural patterns:
+
+**Problem Organization**: All C# problems are implemented as static methods in the `Problem` partial class, decorated with `[LeetCode]` attributes containing metadata (description, difficulty, category, NeetCode video link). Each problem includes inline xUnit tests using `[Fact]` attributes.
+
+**Benchmark Structure**: Each problem has a corresponding benchmark class in the Benchmarks folder that inherits from a base `Benchmark` class. Benchmarks use BenchmarkDotNet with GlobalSetup/GlobalCleanup for test data preparation.
+
+**Console Application**: Built with Spectre.Console, provides an interactive menu system and CLI commands (app, benchmark, info, list, workflow) for running benchmarks and viewing problem information.
+
+**Testing**: Uses xUnit with FluentAssertions for test assertions. Tests are co-located with problem implementations for easy access.
+
+**Package Management**: Uses Directory.Packages.props for centralized NuGet package version management across all projects.
