Description
I am running .Net 4.8 Web Forms application and getting InvalidOperationException. Any help would be appreciated.
internal static void PreStart()
{
System.Diagnostics.Debug.WriteLine(nameof(RegisterServices) + "." + nameof(PreStart) + "() called.");
// If you are using ASP.NET Web Forms without any ASP.NET MVC functionality, remove the call to `.AddMvcDependencyResolver()`.
// If you are using ASP.NET MVC, regardless of whether you're using ASP.NET Web Forms, use `.AddMvcDependencyResolver()`:
_di = new ApplicationDependencyInjectionBuilder()
.ConfigureServices(ConfigureServices)
//.AddMvcDependencyResolver() // Uncomment this out if you're using ASP.NET MVC.
//.AddWebApiDependencyResolver() // Uncomment this out if you're using ASP.NET Web API.
//.AddScopedSignalRDependencyResolver() // Uncomment this out if you're using ASP.NET SignalR (and want to use services scoped to request or operation lifetime). NOTE: You cannot have both `AddScopedSignalRDependencyResolver` and `AddUnscopedSignalRDependencyResolver` at the same time. You must also configure SignalR below.
//.AddUnscopedSignalRDependencyResolver() // Uncomment this out if you're using ASP.NET SignalR (and only need Singleton or Transient lifetime services).
.Build();
}
private static void ConfigureServices(IServiceCollection services)
{
// TODO: Add any dependencies needed here
//services
// // Useful services built-in to AspNetDependencyInjection:
// .AddDefaultHttpContextAccessor() // Adds `IHttpContextAccessor`
// .AddWebConfiguration(); // Adds `IWebConfiguration`
// Example services:
//.AddScoped<Service1>()
//.AddTransient<Service2>()
//.AddScoped<IExampleRequestLifelongService, ExampleRequestLifelongService>()
//.AddScoped<Service4>()
//.AddSingleton<SingletonService>();
}
/// <summary>Invoked at the end of ASP.NET application start-up, after Global's Application_Start method runs. Dependency-injection re-configuration may be called here if you have services that depend on Global being initialized.</summary>
internal static void PostStart()
{
System.Diagnostics.Debug.WriteLine(nameof(RegisterServices) + "." + nameof(PostStart) + "() called.");
}
This error is happening during program startup and prevent the application from starting.
