Loading workflow definitions from JSON

[aksharadeep]

Hello,

I am trying to trigger the workflow using JSON Input. But it is not triggering the workflow or steps mentioned.
Please help if I am missing something.

This is the main method:
static void Main(string[] args)
{
IServiceProvider serviceProvider = ConfigureServices();
string json = File.ReadAllText("steps.json");
var loader = serviceProvider.GetService();
loader.LoadDefinition(json, Deserializers.Json);
}

But I can see the workflow is registered.
Do i need to start/build it somewhere?

This is the workflow class:
public class HelloWorldWorkflow : IWorkflow
{
public void Build(IWorkflowBuilder builder)
{
builder
.UseDefaultErrorBehavior(WorkflowErrorHandling.Suspend);
}

    public string Id => "HelloWorld";

    public int Version => 1;

}

Sample JSON:
{
"Id": "HelloWorld",
"Version": 1,
"Steps": [
{
"Id": "Hello",
"StepType": "WorkflowPOC.Steps.HelloWorld, WorkflowPOC",
"NextStepId": "Bye"
},
{
"Id": "Bye",
"StepType": "WorkflowPOC.Steps.GoodbyeWorld, WorkflowPOC"
}
]
}

I was missing this piece of code. It is now resolved.

host.Start();
host.StartWorkflow(workflow.Id);
Console.ReadLine();
host.Stop();
