Severity Code Description Project File Line Suppression State Error CS0103 The name 'Configuration' does not exist in the current context BankSystem C:\New Project\BankSystem\Startup.cs 24 Active

This error message is indicating that the name 'Configuration' is not recognized in the current context of your code. This could be due to a few reasons:

1. You might not have imported the necessary namespace to use 'Configuration'. If you're using ASP.NET Core, you should have using Microsoft.Extensions.Configuration; at the top of your Startup.cs file.

2. 'Configuration' might not be defined in your Startup class. In an ASP.NET Core application, 'Configuration' is usually defined in the Startup class like this:

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

    public IConfiguration Configuration { get; }
    //...
}

3. If you're trying to access 'Configuration' from another class, you might need to pass it to that class through dependency injection.

Please check these points in your code. If the problem persists, you might need to provide more context or code for a more accurate solution.
