New Post: nuget update adds nuget.core dependency in mvc web app

By the way, here are the injected types defined as a part of the app start up:

string noString = string.Empty;
container.RegisterType(typeof(IPosManContext), typeof(PosManContext), noString, new TransientLifetimeManager());
container.RegisterType(typeof(IcssprodContext), typeof(cssprodContext), noString, new TransientLifetimeManager());
container.RegisterType(typeof(ICacheManager), typeof(CacheManager), noString, new TransientLifetimeManager());
container.RegisterType(typeof(IAdminComponent), typeof(AdminComponent), noString, new TransientLifetimeManager());
container.RegisterType(typeof(IReconcileComponent), typeof(ReconcileComponent), noString, new TransientLifetimeManager());
container.RegisterType(typeof(ICssComponent), typeof(CssComponent), noString, new TransientLifetimeManager());
container.RegisterType(typeof(IEntitlements), typeof(Entitlements), noString, new TransientLifetimeManager());
container.RegisterType(typeof(ILogger), typeof(Logger), noString, new TransientLifetimeManager());

I do not want NuGet involved at run time at all.
Why does my app think that I want NuGet involved at run time?
