![]() There are also a bunch of explicit fluent mappings for the indexes and relationship etc.It also put the connection string directly in the OnConfiguring method with a note that you might not want it there for security reasons.You can see that DbSet properties are created for every one of the Entity classes. ![]() Protected override void OnModelCreating(ModelBuilder modelBuilder)Įntity.Property(e => e.OrderDetailId).HasColumnName( "OrderDetailID") Įntity.Property(e => e.OrderId).HasColumnName( "OrderID") Įntity.Property(e => e.ProductId).HasColumnName( "ProductID") Įntity.Property(e => e.CustomerId).HasColumnName( "CustomerID") Įntity.Property(e => e.EmployeeId).HasColumnName( "EmployeeID") OptionsBuilder.UseSqlServer( Source=(localdb)\ProjectsV13 Initial Catalog=StoreDB ") See for guidance on storing connection strings. #warning To protect potentially sensitive information in your connection string, you should move it out of source code. Protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) Public partial class StoreDBContext : DbContext Now let's look at the new DbContext class. When you run this command, a bunch of new files is added in the Solution Explorer. In this post, we are going to explore how to create a model based on the existing database (Db-First), with the help of Entityframework Core Command then learn how to generate Controller & Views using Scaffolding (Interface & Code-Generator Command) based on model. The provider and connection parameters are required, the provider is and the connection is the connection string for our legacy database. PM> Scaffold-DbContext -Provider -Connection "Data Source=(localdb)\ProjectsV13 Initial Catalog=StoreDB " Now we need to run the scaffold-dbcontext command with just the required parameters. Let's create a new empty project and add all the required packages for EF core which is explained in the Code First approach.
