InMemory

This article describes how to use Orca with InMemory store.

Setup

First add the Orca.Store.InMemory package into your project.

.NET CLI

dotnet add package Orca.Store.InMemory

Package Manager

Install-Package Orca.Store.InMemory

In the Program.cs, register the InMemory store:

builder.Services
  .AddOrca()
  .AddInMemoryStores(Configuration);

AddInMemoryStores method configures Orca stores to use in-memory persistence.

Import configuration

The InMemory store allows importing the configuration from appsettings.json.

if (app.Environment.IsDevelopment())
{
  await ConfigurationHelper.ImportAsync(app.Services, "Orca");
}
