IDENTITY_INSERT is set to OFF
Error:
Cannot insert explicit value for identity column in table 'XYZ' when IDENTITY_INSERT is set to OFF.
Solution:
If you work on ASP .Net vNext with MVC 6.0 and EF 7.0 beta, welcome to hell :-))
It's was kidding.
Solution 1 is add [DatabaseGenerated(DatabaseGeneratedOption.None)] annotation to your ID of your Table (class model)
Solution 2 is add below line to OnModelCreating override method of your DbContext
builder.Entity<XYZ>().Property(i => i.Id).GenerateValuesOnAdd(generateValues: false);

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>();
