This is where I ran into my first problem. Public EventContext( DbContextOptions options) : base( options) This app was using Entity Framework Core and there was a DbSet for the Event class. NodaTime provides a LocalDate type that is perfect for this scenario so I declared a LocalDate property named Date on my Event class. I don’t want to deal with time at all, I’m only interested in the date the event is being held. It might be initially tempting to store the date of the event as a DateTime in UTC, but that’s not necessarily accurate unless the event happens to be held at the Royal Observatory Greenwich. In my app, I needed to model an Event that occurs on a particular date. It helps you to think about your data more clearly, and express operations on that data more precisely. Noda Time is an alternative date and time API for. That’s why the Noda Time library was created, billing itself as a better date and time API for. There is no type that represents a Date on it’s own. For example, how to I represent a date in. NET’s somewhat limited representation of date and time values through the one DateTime class. Open appsettings.If you have ever dealt dates/times in an environment that crosses time zones, you know who difficult it can be to handle all scenarios properly. Let's update appsettings.json with these sections next: Appsettings.json We then use this section to retrieve sub-sections called "Http" and "Smtp"". Notice that we're accessing a configuration section called "Elsa". If you prefer to run the migrations yourself, make sure to pass autoRunMigrations: false when using the UseEntityFrameworkPersistence method (it is an optional parameter set to true by default). If you do not wish to use pooled DB contexts, use the UseNonPooledEntityFrameworkPersistence method instead. When using the Entity Framework Core provider, Elsa will use pooled DB contexts by default and will automatically run migrations for you. Elsa API Endpoints are implemented as regular ASP.NET Core API controllers. Public void Configure( IApplicationBuilder app) WithExposedHeaders( "Content-Disposition")) Services.AddCors(cors => cors.AddDefaultPolicy(policy => policy In a production environment, make sure to allow only origins you trust. Allow arbitrary client browser apps to access the API. AddHttpActivities(elsaSection.GetSection( "Server").Bind) UseEntityFrameworkPersistence(ef => ef.UseSqlite()) Var elsaSection = Configuration.GetSection( "Elsa") Public void ConfigureServices( IServiceCollection services) Public void Build( IWorkflowBuilder builder) => Public HeartbeatWorkflow( IClock clock) => _clock = clock Public class HeartbeatWorkflow : IWorkflow Go ahead and create a new file called HeartbeatWorkflow.cs and add the following code: using
