In-Memory Storage

In-memory storage is commonly used in development and test environments. However, if you use memory-based storage, you lose the reliability guarantee of local transaction messages.

Configuration

To use in-memory storage, you need to install the following package from NuGet:

PM> Install-Package DotNetCore.CAP.InMemoryStorage

Next, add configuration items to the ConfigureServices method of Startup.cs.

public void ConfigureServices(IServiceCollection services)
{
    // ...

    services.AddCap(x =>
    {
        x.UseInMemoryStorage();
        // x.UseXXX ...
    });
}

CAP will clean successful messages from memory every 5 minutes.

Publish with transaction

In-memory storage does not support transactional message publishing.
