# Event Sourcing

> Aggregate-based event sourcing for .NET across any store.

A .NET event sourcing framework for building aggregate-based applications. Provider-agnostic store facades, source-generated aggregates and events, transaction coordination for multi-aggregate saves, queryable snapshots and read models, and storage providers for SQL Server, PostgreSQL, MongoDB, Azure Storage, Azure Cosmos DB, and in-memory.
