Answer: This error means that however you are defining the connection string into the Database Context Factory is somehow not initializing. This happens when you use the really new Microsoft.Extensions.Configuration.Abstruction library. The other way you could resolve this issue is by passing in the Connection String Name that is located under the ConnectionStrings section of the appsettings.json file. This way the Service Repository class where the actual declaration of Database Context is being initialized can pass in the name of the Connection String into the Configuration like below:

 public MyDbContext CreateDbContext(string nameOfConnectionString)
            var builder = new DbContextOptionsBuilder<MyDbContext>();

                       Configuration.GetConnectionString(nameOfConnectionString), sqlServerOptionsAction: sqlOptions =>

            catch (Exception ex)

            return new MyDbContext(builder.Options);
