No external dependencies ,simply dotnet run TaskManager.Api InMemory Db seeds itself with initial data, you can use this list of predefined IDs to test

Guid TaskListId = new Guid("3582b784-669e-49c9-bcf4-0d4b336e8003");
Guid UserId = new Guid("dbe4dd38-54b7-4b9c-a831-a480c74bfd91");
Guid UserId2 = new Guid("5bab8aa3-e66c-421d-a2cf-02708d47b929");
Guid UserId3 = new Guid("5e747c0b-4c42-4ed3-9592-409105546e3a");

Solution implemented with Clean Architecture in mind, it consists of 4 main layers ((Api, Infra) - Presentation -> Application -> Domain ( which has our table modules from EF)

EF Core with InMemoryDb(Code first approach), Automapper so we don't leak our domain entities outside, CQRS with MediatR library for our Presentation -> Application communication, Repository pattern without UOW for the sake of simplicity

##Notes Access policies are implemented only in DeleteTaskList, RevokeUserAccessToTaskList
