Activities of "ruffzy"

When I map one of my object to the dto I get a stackoverflow exception. This is because I am using a self referencing object. Fortunately automapper allows setting a configuration in startup.cs to prevent that behaviour.

//MVC
            services.AddMvc(options =>
            {
                options.Filters.Add(new CorsAuthorizationFilterFactory(DefaultCorsPolicyName));
            }).AddJsonOptions(opt =>
            {
                opt.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Serialize;
            });

But as I still get the stackoverflow exception after setting the option I guess that in ABP I have to configure that somewhere else. Where?

I am using the new angular 2 / asp.net core project with VS 2017 update 1 . After I have added some new entities I wanted to create a new migration as described in the documentation with the following command:

dotnet ef migrations add "created_new_BM_entities"

Unfortunately the dotnet-ef.exe crashes with the following exception:

PM> dotnet ef migrations add "created_new_BM_entities"

Can you please explain what I am doing wrong here?

kind regards, marco

Hi,

when I run the Migrator project to create a new Migration I'll get an AutomaticMigrationsDisabledException. And the message is: Unable to update database to match the current model because there are pending changes and automatic migration is disabled. Either write the pending model changes to a code-based migration or enable automatic migration. Set DbMigrationsConfiguration.AutomaticMigrationsEnabled to true to enable automatic migration.

In another post I have seen that I would make sense now to run the database update command in the package manager console. But when I run Update-Database I get again an error: No DbContext was found in assembly 'enio.Web_Manager.EntityFramework'. Ensure that you're using the correct assembly and that the type is neither abstract nor generic.

Btw, I have selected EntityFramework as my Default project in the drop down list. What is also a bit strange is that I also receive the following message:

Both Entity Framework Core and Entity Framework 6 are installed. The Entity Framework Core tools are running. Use 'EntityFramework\Update-Database' for Entity Framework 6.

When I try executing EntityFramework\Update-Database I get the following exception: The EntityFramework package is not installed on project 'enio.Web_Manager.EntityFramework'.

Can you please give me an idea where to look for a solution? Do I have to use the commands for Entity Framework Core or Entity Framework 6 ?
