Fresnel is a .NET library that accelerates the discovery, analysis, and design phase of projects using Domain Driven Design.

Build .NET domain models that run as interactive prototypes, then use those prototypes to explore the domain model with your team and your Domain Experts.

Fresnel is built using Blazor on .NET 8.
