Chat with Your .NET Assembly and Generate Working Code

Upload DLL, EXE, or NuGet Package

Drop your managed .NET assembly or select a .nupkg file. The system extracts public API metadata, builds a searchable RAG index, and prepares an AI assistant familiar with your code.

Chat with Your .NET Assembly and Generate Working Code

Upload a DLL or NuGet package — AI reads metadata, builds a RAG index, and answers questions about your assembly.

Upload a DLL or NuGet package. Our AI reads metadata, builds a RAG index, and lets you ask questions, generate code samples, and visualize architecture.

AI Assembly Chat starts with static analysis, not guesswork. When you upload a DLL, EXE, or NuGet package, .NET reflection walks its public surface — namespaces, classes, interfaces, enums, methods, properties, and any XML doc comments attached to them — while internal and private members are excluded. This gives the AI ground truth about your specific assembly version instead of relying on generic training knowledge of the package.

That extracted metadata, along with inferred usage patterns, is embedded and indexed for semantic search (RAG), so a question like "how do I serialize an object with this library" retrieves the actual relevant methods and their real signatures rather than a plausible-sounding guess. This indexing step is what lets answers stay accurate even for internal, uncommon, or recently changed APIs that a general-purpose model would never have seen.

Retrieved signatures and doc comments then ground the AI's response: working C#/F# code samples with correct using statements and async patterns, plain-language explanations of what a type or method does, or on-demand SVG class diagrams and PlantUML sequence diagrams showing how the real API pieces connect. Nothing you upload is stored beyond your session or used to train models.

How Assembly Chat Works

1. Upload Your .NET Assembly

Select a DLL, EXE, or .nupkg file from your local machine or CI pipeline.

2. AI Extracts Public API Metadata

The system reflects over the assembly to map namespaces, classes, interfaces, enums, delegates, methods, properties, fields, and custom attributes.

3. RAG Index for Fast Semantic Search

API signatures, XML comments, and inferred behaviors are vectorized and indexed, enabling instant question answering.

4. Chat, Generate Code & Diagrams

Ask "How do I use X?", "Show me an example of Y", or "Generate a sequence diagram for Z". AI replies with code, explanations, and visual diagrams.

FAQs

Any managed .NET assembly (DLL, EXE) targeting .NET Framework 4.6.2+, .NET Core 3.1+, .NET 5-8. Also supports .nupkg NuGet packages.
Public types and their public/protected members. Internal and private members are excluded for security and relevance.
High accuracy because the AI reads actual method signatures, parameter types, return types, and XML docs from your specific assembly version.
No. Extracted metadata is temporarily indexed for your session. Files are not permanently stored or used to train models.
SVG class diagrams, PUML (PlantUML) sequence and component diagrams showing public API relationships and call flows.
