Dependency Injection

Once you setup dependency injection for your flow library, you can use it in your flows.

Flow constructor

To use dependencies inside of your flow definitions, all you need to do is inject them into the flow constructor as is normal procedure. Typically, I inject my dependencies and set them as private readonly fields.

For example, if I want to use IServiceA in my flow, I would do the following:

using DidactCore.Flows

namespace FlowLibrary
{
    public class MyFlow : IFlow
    {
        private readonly IServiceA _serviceA;

        public MyFlow(IServiceA serviceA)
        {
            _serviceA = serviceA;
        }

        // ...

        public async Task ExecuteAsync(IFlowExecutionContext context)
        {
            await _serviceA.DoSomething();
        }
    }
}

Flow registration

Just as a quick reminder, you do not have to register the flows themselves for dependency injection; you only need to register the flows' dependencies.
