I am having Asp.Net 3.1 application, and I am getting error After updating my nuget packages 'Microsoft.EntityFrameworkCore' in below line as

'The specified field '_redirectUris' cannot be used for the property 'ClientApplication.RedirectUrisList' because it does not match the property name.'

modelBuilder.Entity<TestApplication>().Property<string>("RedirectUrisList").HasField("_redirectUris");

Hi TechAspirant ,

From the related github issue , it seems that this method still has problems in 3.0 and is not applicable

Here is workaround to make modification as follows:

Model

 public class TestApplication
    {
        private string _redirectUris;

        public int Id { get; set; }

        public string Name { get; set; }

        public string RedirectUrisList => _redirectUris;
    }

DbContext

modelBuilder.Entity<TestApplication>().Property(t=>t.RedirectUrisList).HasField("_redirectUris");

Best Regards,

Sherry

I am getting error as below

System.InvalidOperationException: 'The specified field '_redirectUris' of type 'string' cannot be used for the property 'ClientApplication.RedirectUris' of type 'IEnumerable<string>'. Only backing fields of types that are assignable from the property type can be used.'

public IEnumerable<string> RedirectUris
    {
      get => EnumerationToStringConverter.CreateEnumerationFromString(_redirectUris);
      set => _redirectUris = EnumerationToStringConverter.CreateStringFromEnumeration(value, _redirectUris);
    }

modelBuilder.Entity<TestApplication>().Property(t=>t.RedirectUrisList).HasField("_redirectUris");

Sql does not support a column as an array type, so there is no way to map a database field to a enumerator. It looks you really wanted to map to a enum, which can be done
