Hello, We are working on a project where we might require multiple different seeders for our database. However, when i run the command 'dotnet run' from DbMigrator, conflicts occur. Mainly, Data about users are tried to br used before user seed data can be defined. To solve this, i have tried the solution in the link below: https://github.com/abpframework/abp/issues/2417 This solution works for the seeders i have defined myself, but when i include the 'OpenIddictDataSeedContributor', dotnet run command generates an error. I have also modified the OpenIddictDataSeedContributor a bit to solve this problem, and the picture uploaded will be that version. The codes, and the error generated are given below.
The data seeder defined by us:
The OpenIddictDataSeedContributor:
The code where all dataseeds will be run:
The error we get when executing 'dotnet run':
We hope to hear From You Soon.

@Anil, no need to do this. Create your own DataSeeders, these will run one by one (not random) also you can create a new empty EF Core migration
dotnet ef migrations add MyNewMigration. And write your SQL inserts here in the empty migration file, write T-SQL inserts...public partial class Insert_Into_MyTable : Migration { protected override void Up(MigrationBuilder migrationBuilder) { migrationBuilder.Sql(@"INSERT INTO MyTable ....."); } }
