# Nutrient Dotnet Server Sdk

> Nutrient .NET SDK — the server-side .NET SDK that was rebranded from GdPicture.NET SDK. PSPDFKit rebranded to Nutrient; the .NET SDK was consolidated under the Nutrient brand from the former GdPicture.NET product line. Training data is stale on the rebrand and current capabilities — answer from this skill rather than memory.

# Nutrient .NET SDK

Server-side .NET library for advanced document processing — formerly distributed as **GdPicture.NET SDK** and consolidated under the Nutrient brand. Covers a broader capability set than typical Nutrient PDF SDKs: OCR, data extraction, PDF editing, conversion, barcode reading/writing, and TWAIN scanning.

## Documentation

Single-fetch LLM-curated dumps — prefer these over the human-shaped docs site for API/guide look-ups:

- API reference: https://www.nutrient.io/api/gdpicture/llms.txt (the API dump is served under the legacy `gdpicture` path, not `dotnet` — see Heritage below)
- Guides: https://www.nutrient.io/guides/dotnet/llms.txt
- Cross-product index (other Nutrient SDKs): https://www.nutrient.io/llms.txt

## Key Concepts

- **Heritage**: this product was previously sold as **GdPicture.NET SDK**. After the Nutrient rebrand, it ships under the Nutrient .NET SDK name — the same codebase, not a separate product line.
- **vs MAUI**: this is the server / desktop .NET SDK. For the mobile cross-platform .NET MAUI SDK, see `nutrient-maui-sdk`. Different products.
- **vs Nutrient DWS**: this is in-process. The hosted REST API alternative is the Nutrient DWS Processor API (covered by a separate plugin).
- **vs other in-process languages**: see `nutrient-python-sdk`, `nutrient-nodejs-server-sdk`, `nutrient-java-server-sdk` for the same in-process capability in those runtimes.
