No service for type

Error:
An unhandled exception occurred while processing the request.
Exception: TODO: No service for type 'ABC.Services.XYZService' has been registered.
Microsoft.Framework.DependencyInjection.ServiceProviderExtensions.GetRequiredService(IServiceProvider provider, Type serviceType)

Solution:
If you have a new Service in your ASP .Net vNext, you need to add below line in ConfigureServices(IServiceCollection services) function in Startup.cs for register it ;-)

services.AddTransient<XYZService>();

PS: At this time ASP .Net vNext, Visual Studio 2015 and MVC 6.0 are beta version.

Update 1: it could be solved with this services.AddScoped<XYZService>();

The service cannot be activated

Error:
The service cannot be activated because it does not support ASP.NET compatibility. ASP.NET compatibility is enabled for this application. Turn off ASP.NET compatibility mode in the web.config or add the AspNetCompatibilityRequirements attribute to the service type with RequirementsMode setting as 'Allowed' or 'Required'.

Solution:
Add this line in top your Service class
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
