NEventStore is a persistence-agnostic event store library for .NET that abstracts different storage implementations behind a common API. It is designed for event sourcing in DDD and CQRS applications and supports JSON, BSON, and MessagePack serialization.

Use cases

• implement event sourcing in a .NET application
• build a CQRS application with domain events
• swap storage backends for an event store without changing application code
• persist aggregate event streams in a DDD application
• serialize events to JSON, BSON, or MessagePack
• poll for new events from an event store

When to choose

• you are building a .NET DDD/CQRS application with event sourcing
• you want a storage-agnostic event store abstraction with pluggable persistence providers
• you need a mature, MIT-licensed event sourcing library for .NET Standard or .NET Framework

When to avoid

• you need a general-purpose message or stream store rather than event sourcing persistence
• you are not on the .NET platform
• you need a hosted event store with built-in projections and subscriptions
