To set the default document programmatically in an ASP.NET Core Web App (Razor Pages), you can add a middleware in the Configure
method of the Startup.cs
file. However, since you mentioned that you do not have a Startup.cs
file in your project, you can try adding the following code to the Program.cs
file:
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Hosting;
namespace YourNamespace
{
public class Program
{
public static void Main(string[] args)
{
CreateHostBuilder(args).Build().Run();
}
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
webBuilder.UseDefaultServiceProvider(options =>
options.ValidateScopes = false);
webBuilder.UseWebRoot("wwwroot");
webBuilder.UseDefaultFiles(new DefaultFilesOptions
{
DefaultFileNames = new[] { "Index.cshtml" }
});
});
}
}
The UseDefaultFiles
method is used to specify the default file names for a directory. In this case, it is set to Index.cshtml
. You can replace this with the name of your default file.
Note that this approach assumes that your Razor Pages are located in the wwwroot
folder. If they are located elsewhere, you will need to adjust the UseWebRoot
method accordingly.
