Issue with configuration for dotnet core web api

[ADringer]

Hi,

I'm having an issue running EventFlow with the latest version in dotnet core web api. I have the following setup:

services.AddEventFlow(options =>
                options
                    .AddAspNetCore(o => o.AddDefaultMetadataProviders())
                    .AddDefaults(typeof(AgencyCreatedEvent).Assembly)
                    .AddDefaults(typeof(Startup).Assembly)
                .ConfigureMsSql(MsSqlConfiguration.New
                    .SetConnectionString(@"Server=(localdb)\mssqllocaldb;Database=EventFlowDb;User Id=eventFlow;Password=Password!"))
                .UseMssqlEventStore()
                .ConfigureEntityFramework(EntityFrameworkConfiguration.New)
                .AddDbContextProvider<AgencyContext, MsSqlDbContextProvider>()
                .UseEntityFrameworkReadModel<AgencyReadModel, AgencyContext>()
                .UseEntityFrameworkReadModel<ManagementServiceReadModel, AgencyContext>()
                .CreateResolver());

But is coming up with the error:

No versioned type definition for 'AgencyCreatedEvent' with version 1 in 'EventDefinitionService'

I have added the following attribute to the event:

 [EventVersion("AgencyCreated", 1)]
    public class AgencyCreatedEvent : IAggregateEvent<Agency, AgencyId>
    { }

But still get the same issue. With this latest version I can not run EventFlow at all.

Please try calling RunBootstrapperOnHostStartup in AddAspNetCore. Seems I need to change the design and make this opt-out instead of opt-in...

@frankebersoll Still get the same error. My startup now looks like:

services.AddEventFlow(options =>
                options
                    .AddAspNetCore(o => o.RunBootstrapperOnHostStartup().AddDefaultMetadataProviders())                  
                    .AddDefaults(typeof(AgencyCreatedEvent).Assembly)
                    .AddDefaults(typeof(Startup).Assembly)
                .ConfigureMsSql(MsSqlConfiguration.New
                    .SetConnectionString(@"Server=(localdb)\mssqllocaldb;Database=EventFlowDb;User Id=eventFlow;Password=Password!"))
                .UseMssqlEventStore()
                .ConfigureEntityFramework(EntityFrameworkConfiguration.New)
                .AddDbContextProvider<AgencyContext, MsSqlDbContextProvider>()
                .UseEntityFrameworkReadModel<AgencyReadModel, AgencyContext>()
                .UseEntityFrameworkReadModel<ManagementServiceReadModel, AgencyContext>()
                .CreateResolver());

Found the issue. Originally I hadn't set any EventVersion attributes on my events. I then updated to the latest nuget package and started getting that error.

After purging the database (I'm only doing a POC) and started saving events it started working. It looks like the latest version expects events to have the EventVersion attribute?

Need to investigate this

Work on event naming is scheduled in #907, closing this as the original issue was found and there's already an issue for the event naming
