Let's say I'm a new developer in a company. So there is already an existing database for the project. To work on the project, obviously I need to scaffold the existing database(database first approach), which can generate model classes for me to work on. So I start to work on the project and want to add a new column to a table, so I add a new property on the model class then I want to apply this change in the database. So I switch back to code first approach by adding a new migration and update the database. But the problem is, if I add a new migration, EF will include all the data model

I try do adhere DDD principles on C# collections see more here And I notice that the model builder method for initial seed HasData relies on the Add Method of ICollection . There is any way to circumvent or trick that method when is called from database update / migrate process? All I had done until now to trick it follows this path. 1) Create a wrapper around the ICollection named ReadOnlyKollection 2) Have a private ICollection on the model, to avoid exposing to the outside world the collection. 3) Expose the wraper making obsolete Add and some other methods that will trow

I've got a Solution with many projects. One of them ( Domain ) is a .NET Standard 2.0 project where I made my EF Core DbContext implementation for which I want to enable database migrations . I saw various blogs and Q/A forums where the problem was explained but none of the proposed solutions seem to work for me because of the .NET Core newer version or (probably) for my particular solution configuration. Solution projects Engine (.NET Core 2.1 Console App) Web API (.NET Core 2.1 Library) Application (.NET Core 2.1 Library) Domain (.NET Standard 2.0 Library) WindowsService (.NET Core 2.1

I successfully deployed a .NET Core Console Application to my Windows IoT running on a Raspberry Pi 3. The application pulls data from a webservice and stores them in a database. I used Entity Framework Core for that. When I start the deployed console application (.exe) through the remote powershell everything works except the access to my database running on Azure. When the application tries to read from the database it throws the following exception: System.TypeInitializationException: The type initializer for 'System.Data.SqlClient.TdsParser' threw an exception. ---> System

Im having two models: public class Customer { public int Id { get; set; } public int Number { get; set; } public int ParentNumber { get; set; } public string Name { get; set; } public string Address { get; set; } public string City { get; set; } public string Country { get; set; } public string Language { get; set; } } and public class Batch { public int Id { get; set; } public int Number { get; set; } public string FileName { get; set; } public string ArticleNumber { get; set; } public string ArticleDescription { get; set; } public int Weight { get; set; } public DateTime ProductionDate { get

I'm having an issue with DescriptionAttribute in ASP.NET 5 project.
