Configuration does not exist in current context Core 2.0

[sipi41]

In the first example of the book, it is instructed to do the following:

public void ConfigureServices(IServiceCollection services) { // Add framework services. services.AddDbContext<BlogContext>(options => options.UseSqlServer(Configuration.GetConnectionString(" DefaultConnection"))); services.AddMvc(); }

But when I want to use the part of Configuration.GetConnectionString, I get a red line under saying: "The name "Configuration does not exist in current context"

Please help! (see attached file below)

As nobody took some time to answer, here's the answer:

Configuration IS a variable we should create into the "Startup Class", this is what I did according to other book called "Pro ASP.NET Core MVC 2"

private IConfiguration Configuration { get; }
public Startup(IConfiguration configuration)
=> this.Configuration = configuration;

Basically, we create a private variable of type IConfiguration, then we create a constructor for the Startup class with injection of an IConfiguration object, then pass the created object to the private IConfiguration variable we just created.

Why the book does not explain this?

I've only had this issue arise (adding the DI of an IConfiguration object into the Startup class) when starting from an Empty project with no scaffolding (API or MVC Core 2.x).

Thank you sipi41 for coming back and answering this.
