在Asp.Net Core 2.X中部署后无法解析DbContext

Question

I have a webapi in asp.net core 2.1 and that is working properly if I press F5 from the Visual Studio, I can hit my controllers, but when I deploy the application to the IIS, it says that it can resolve the DbContext on the Configure method.

My Configure looks like this

 public void Configure(IApplicationBuilder app, IHostingEnvironment env, IConfiguration configuration, DocumentDbContext documentContext)
        { …}

on my ConfigureServices I inject the dbcontext on this way

container.AddDbContext<DocumentDbContext>(options => options.UseSqlServer(connectionString), ServiceLifetime.Scope);

and as I said is working. In order to deploy the application to an IIS I added the following information on the Program class

 public class Program
    {
        public static void Main(string[] args)
        {
            var host = BuildWebHost(args);

            host.Run();
        }

        public static IWebHost BuildWebHost(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseKestrel()
                .UseContentRoot(Directory.GetCurrentDirectory())
                .UseIISIntegration()
                .UseStartup<Startup>()
                .Build();
    }

The ApplicationPool is running under No Managed Code do I need to check something else?

Answer 1

Issue was identified to be the connection string was using integrated security which was not working when deployed to run under IIS as web app was running under application pool identity. Since application pool identity does not have access to database, connection was failing.

Suggested fix was to create a new sql server login, assign that user to application database, update connection string to use the userid and password instead of integrated security.
