EF 忽略 ON DELETE CASCADE 的 fluent API

Question

I have this code:

  modelBuilder.Entity<ProductDetails>()
          .HasRequired(c => c.Product)
          .WithMany()
          .WillCascadeOnDelete(false);

However when I check the table definition generated I see:

 CONSTRAINT [FK_dbo.ProductDetails_dbo.Product_ProductId] FOREIGN KEY ([ProductId]) REFERENCES [dbo].[Product] ([Id]) ON DELETE CASCADE

What am I missing? why does it create the ON DELETE CASCADE ?

Answer 1

I believe there is an issue with EF in the syntax above. When I reverse the definition like described below, it works:

  modelBuilder
         .Entity<Product>()
         .HasMany(p => p.Details)
         .WithRequired()
         .WillCascadeOnDelete(false);
