The name "Configuration" does not exist in the current context

When trying to register a database context in startup.cs

public void ConfigureServices(IServiceCollection services)
{
        services.AddMvc(option => option.EnableEndpointRouting = false);
        services.AddDbContext<PostDbContext>(options =>
        options.UseSqlServer(Configuration.GetConnectionString("PostDbContext")));
 }

I get error

The name "Configuration" does not exist in the current context.

All code examples are taken from the official Microsoft documentation. Tutorials -> MVC -> Get started -> Add model. ASP.NET Core version: 3.1 How fix it?

If you are using dotnet 6 and the above solution no longer applies because they got rid of the startup file... try the below answer.

Configuration.GetConnectionString(string connName) in .NET6 is under builder:

var builder = WebApplication.CreateBuilder(args);
string connString = builder.Configuration.GetConnectionString("DefaultConnection");

also AddDbContext() is under builder.Services:

builder.Services.AddDbContext<ApplicationDbContext>(options =>
{
    options.UseSqlServer(builder.Configuration.GetConnectionString("DefaultConnection"));

});

I hope it helps.

This problem occurs because you have not defined Configuration which is an instance of IConfiguration interface like this-

public IConfiguration Configuration { get; }
public Startup(IConfiguration configuration)
{
   Configuration = configuration;
}

Here Configuration is important to define which checks configuration details. For Ex.-Configuration.GetConnectionString("Your Connection String") checks the connection string from appsettings.json file to get or set data in database.

I have not defined a configuration.

public IConfiguration Configuration { get; }
public Startup(IConfiguration configuration)
{
    Configuration = configuration;
}
