Using QuantLib.NET for Bond Analytics in C#

Summary

The document asks for open-source C# tools to calculate fixed-income measures such as yield to maturity and duration. An answer recommends QuantLib.NET, noting its use for bond pricing in back-office work and a soft real-time trading system.

This is a brief tool recommendation rather than a tutorial or comparison. It provides no implementation details, accuracy assessment, or discussion of supported analytics, so readers would need to consult the library's documentation and other sources to determine whether it fits a particular workflow.

Key ideas

• QuantLib.NET is suggested for fixed-income analytics in C#.
• The answer reports its use for bond pricing in back-office and soft real-time trading systems.
• The document gives no code, feature comparison, or validation of specific calculations.

I'm doing some Fixed Income analytics work and wanted to know if there where any opensource C# libraries that I could use in order to avoid writing functions for generic calculations like YTM and Duration.

Thanks for the help, Rafael

Have you looked at Quantlib.net? We use it both in the back office and some soft realtime trading system for pricing bonds.

There are a few questions on this site that deal with using it for pricing bonds.
