    We emailed the log file to liming.ma@volosoft.com

    We are able to inject IWorkflowInvoker in web project and it is working. whenever trying to inject in AppService/Controller, We are getting ActivatorChain error.

    hi

    Your ConfigureElsa in the MicroServiceDemoWebModule

    and MicroServiceDemoWebModule depends on ProductServiceWebModule that's the way you can inject the IWorkflowInvoker

    but the application doesn't call ConfigureElsa

    eg call ConfigureElsa in MyCompanyName.MyProjectName.IdentityService.HttpApi.Host then you can use IWorkflowInvoker in MyCompanyName.MyProjectName.IdentityService.Application
