Facing the above issue while implementing the graphql services with dot net web api.
public class UserModel
{
public List<IAddress> Addresses { get; set; }
}
This is query
public class Query
{
readonly IUserService _userService = null;
public Query(IUserService userService)
{
_userService = userService;
}
public List<UserModel> Users => _userService.GetUsers();
}
This is configuration
public void ConfigureServices(IServiceCollection services)
{
_ = services.AddMvc();
_ = services.AddControllers();
_ = services.AddSingleton(CreateClusterClient);
_ = services.AddScoped<IUserService, UserService>();
_ = services.AddScoped<Query>();
_ = services.AddGraphQLServer().AddQueryType<Query>();
_ = services.AddGraphQLServer().AddType<UserType>();
}
I am using the above configuration, Model, Query and other stuff.
