I'm attempting to call a scoped Service inside of an IHostedService to run a background task that interacts with the database. Basically it is telling me my scoped service is not a registered service.



This is the line I'm using to register the Service from Startup.cs



services.AddScoped<IIdeaService, IdeaService>();


This is the implementation of that Service in my Hosted Service



using (var scope = _serviceScopeFactory.CreateScope())

var scopedIdeaService = scope.ServiceProvider.GetRequiredService<IdeaService>();

foreach (var idea in ideaList.Ideas)

var exists = await scopedIdeaService.GetIdeaByIdAsync(idea.IdeaId);

var updatedIdea = AddIdeaDataForDatabase(idea, exists);

if (exists == null)

await scopedIdeaService.CreateIdeaAsync(await updatedIdea);

else

await scopedIdeaService.UpdateIdeaAsync(await updatedIdea);





The exact error i'm receiving is:




System.InvalidOperationException
HResult=0x80131509
Message=No service for type 'BrightIdeaService.Services.BrightIdea.IdeaService' has been registered.
Source=Microsoft.Extensions.DependencyInjection.Abstractions
StackTrace:
at Microsoft.Extensions.DependencyInjection.ServiceProviderServiceExtensions.GetRequiredService(IServiceProvider provider, Type serviceType)
at Microsoft.Extensions.DependencyInjection.ServiceProviderServiceExtensions.GetRequiredService[T](IServiceProvider provider)
at BrightIdeaService.Services.BrightIdea.BrightIdeaReportingDownload.d__6.MoveNext()




I'm trying to understand if I'm registering my service incorrectly or if I'm declaring the scope incorrectly. It is entirely possible I just don't know what I'm doing also. Suggestions would be appreciated.
