Polecat.AspNetCore

ASP.NET Core helpers for applications built on Polecat, the SQL Server-backed event store in the Critter Stack.

Install

dotnet add package Polecat.AspNetCore

What it gives you

Write event streams straight to the response. WriteStreamState and WriteEvents serialize a stream's aggregate or its raw events using the store's own serializer, so the wire format matches what Polecat persists:

app.MapGet("/orders/{id:guid}", (Guid id, HttpContext context, IQuerySession session)
    => context.Response.WriteStreamState<Order>(session, id));

ETag helpers for optimistic concurrency. ETagHelpers formats a stream version — Guid or long — as an HTTP ETag and checks incoming If-None-Match headers, so a caller can be told 304 Not Modified without you reloading the aggregate.

MCP endpoints. MapPolecatMcp exposes the event store over the Model Context Protocol for agent-driven exploration of streams and events.

Requirements

.NET 9 or .NET 10
A configured Polecat IDocumentStore — see the Polecat package
