IServiceCollection StackOverflow exception

Question

I tried moving all my DI instructions to a separate class using an extension method, on runtime I get a stack-overflow exception with no further details

public static IServiceCollection AddMyServices(this IServiceCollection services)
{
    var dns_client = new LookupClient();

    services.AddSingleton<ImySQLService, mySQLService>();
    services.AddSingleton<ILoggerService, LoggerService>();
    services.AddSingleton<IOrginizationRepository, OrginizationRepository>();
    services.AddSingleton<IEdiModelRepository, EdiModelRepository>();
    services.AddSingleton<IEdiUserProfileRepository, EdiUserProfileRepository>();
    services.AddSingleton<IEdiSegmentRepository, EdiSegmentRepository>();
    services.AddSingleton<IConnectionRepository, ConnectionRepository>();
    services.AddSingleton<IVariableRepository, VariableRepository>();
    services.AddSingleton<ISegmentPictureRepository, SegmentPictureRepository>();
    services.AddSingleton<IAuthorizationHandler, HasScopeHandler>();
    services.AddSingleton<IEdiExampleRepository, EdiExampleRepository>();
    services.AddSingleton<IDocumentReceiverRepository, DocumentReceiverRepository>();
    services.AddSingleton<IDocumentToEdiRepository, DocumentToEdiRepository>();
    services.AddSingleton<IEdiValidatorRepository, EdiValidatorRepository>();
    services.AddSingleton<IDnsLookupRepository, DnsLookupRepository>();
    services.AddSingleton<ILookupClient>(dns_client);
    services.AddHttpClient<IPylonAPIService, PylonAPIService>();
    ...

    return services;
}

• What could possibly be causing this?
• How would I got about debugging such an exception that has no further messages
• I tried to wrap it with try - catch but to no avail

Thanks in advance!

Answer 1

I found the problem, I had

builder.Services.AddMyServices();

twice , once in my Program.cs and once in the Extension Method itself
