Host in ASP.NET Core

Add SereinFlow to an existing ASP.NET Core app from the SereinFlow.AspNetCore assembly, targeting .NET 10.

Minimal setup

After referencing SereinFlow.AspNetCore, add:

using SereinFlow.AspNetCore;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddSereinFlow(options =>
{
    options.UseWebApi();
    options.UseMcp();
});

var app = builder.Build();
app.UseSereinFlow();
app.MapSereinFlow();
app.Run();

Enable at least one of UseWebApi() or UseMcp(). Call AddSereinFlow, UseSereinFlow, and MapSereinFlow once each in the same host, and map routes before starting it.

What the three calls do

Call	Purpose
builder.Services.AddSereinFlow(...)	Register storage, application and execution services, plus enabled Web API or MCP services.
app.UseSereinFlow()	Add required middleware and, when enabled, Swagger UI.
app.MapSereinFlow()	Map REST controllers, run/workspace SignalR hubs, and the HTTP MCP endpoint when enabled.

With Web API enabled, hubs are at /hubs/runs and /hubs/workspace. Swagger is enabled in Development by default; set UseWebApi(api => api.EnableSwagger = true) to enable it explicitly. SereinFlowWebApiOptions also configures CORS origins, OpenAPI, and Swagger UI paths. Set the MCP path with UseMcp(mcp => mcp.EndpointPath = "/mcp").

Verify it

Start the host and check health as in Quick start, then create a flow in the console. For node-accessible functions, see Built-in services. For host registrations, see Internal service registration.
