A powerful command-line tool for analyzing NuGet packages and .NET assemblies using reflection. Quickly explore package contents, types, methods, and properties without writing code or digging through documentation.

• NuGet Package Analysis: Download and analyze any NuGet package directly by name
• Local DLL Analysis: Inspect .dll files from your filesystem
• Comprehensive Type Information: View all public types including classes, interfaces, enums, and structs
• Member Details: See constructors, properties, methods, and events with clear formatting
• Smart Dependency Resolution: Automatically resolves assembly dependencies
• Beautiful Console Output: Color-coded output with intuitive icons for easy reading
• Safe Inspection: Uses reflection without executing any code from analyzed packages

• .NET SDK 6.0 or later
• Internet connection (for NuGet package analysis)

git clone https://github.com/sojohnnysaid/PackageAnalyzer.git cd PackageAnalyzer dotnet build

dotnet tool install -g PackageAnalyzer

dotnet run Newtonsoft.Json dotnet run Serilog dotnet run Microsoft.EntityFrameworkCore

dotnet run /path/to/your/assembly.dll

dotnet run help

For packages with extensive APIs, pipe the output to less for easier navigation:

dotnet run Microsoft.EntityFrameworkCore | less

The analyzer uses icons and colors to make the output easy to understand:

• 📘 Regular Class
• 🔒 Static Class
• 🎨 Abstract Class
• 🔌 Interface
• 📝 Enum
• 📦 Struct

• Yellow: Constructors
• Green: Properties
• Cyan: Methods
• Magenta: Events

╔═══════════════════════════════════════════════════════════════╗ ║ 📦 PACKAGE: Newtonsoft.Json v13.0.3 ║ ╚═══════════════════════════════════════════════════════════════╝ 🗂️ Namespace: Newtonsoft.Json ──────────────────────────────────────────────────── 📘 JsonConvert (static class) Methods: • static string SerializeObject(object value) • static T DeserializeObject<T>(string value) • static void PopulateObject(string value, object target) 🔌 IJsonLineInfo (interface) Properties: • int LineNumber { get; } • int LinePosition { get; } Methods: • bool HasLineInfo() 

1. Creates a temporary .NET project
2. Uses dotnet add package to download from NuGet
3. Locates the package in the NuGet cache
4. Finds the best matching framework version
5. Loads assemblies using .NET Reflection
6. Analyzes all public types and members
7. Cleans up temporary files automatically

1. Loads the assembly directly from the specified path
2. Automatically resolves dependencies from:
   • Same directory as the DLL
   • NuGet cache for known packages
3. Analyzes all public types and members

The analyzer automatically selects the best framework version from the package, with preference for:

• .NET 8.0
• .NET 7.0
• .NET 6.0
• .NET 5.0
• .NET Standard 2.1
• .NET Standard 2.0
• .NET Core 3.1

• API Exploration: Quickly understand what a NuGet package offers
• Dependency Analysis: See what types and methods are available in a library
• Documentation Alternative: Get a quick overview when documentation is lacking
• Learning Tool: Explore how popular packages are structured
• Migration Planning: Understand APIs before upgrading package versions
• Security Review: Inspect package contents without executing code
