Cannot set value of Manual Identity Type

[RuiAlias]

Hi, I'm trying to create an entity with not-auto-generated primary key. To achieve that, I created an entity and modified the identity property to have an "Identity Type" of "Manual".

I expected to see this property being generated in the entity's constructor, since it's required and not-auto-generated. However, that's not what's happening. The generated class does not expose a way to set the value of the identity property: the property does not appear in the constructor and its setter is private.

As such, I cannot create entities of this type in my code.

Example

         modelBuilder.Entity<global::BottomUp.Model.Currency>()
                     .ToTable("Currency")
                     .HasKey(t => t.Code);

         modelBuilder.Entity<global::BottomUp.Model.Currency>()
                     .Property(t => t.Code)
                     .HasMaxLength(3)
                     .IsRequired()
                     .ValueGeneratedNever();

      /// <summary>
      /// Public constructor with required data
      /// </summary>
      /// <param name="name">Name of language in English</param>
      /// <param name="symbol">Currency symbol</param>
      public Currency(string name, string symbol)
      {
         if (string.IsNullOrEmpty(name)) throw new ArgumentNullException(nameof(name));
         this.Name = name;
         if (string.IsNullOrEmpty(symbol)) throw new ArgumentNullException(nameof(symbol));
         this.Symbol = symbol;
         Init();
      }

      /// <summary>
      /// Static create function (for use in LINQ queries, etc.)
      /// </summary>
      /// <param name="name">Name of language in English</param>
      /// <param name="symbol">Currency symbol</param>
      public static Currency Create(string name, string symbol)
      {
         return new Currency(name, symbol);
      }

Each constructor calls the partial method Init which allows you to add constructor logic in a central location and have it execute in every constructor (note, though, that if you add your own constructors, you're on the hook for calling Init from that constructor as well :-) ). In the current version, this is typically where you would set the entity's identifier.

In the very-soon-to-be-released v1.3.0.5, though, manually-set identifiers have indeed been added to the public constructors. See #93 .

Hope that helps.

Thanks! And sorry for the duplicate issue.

It certainly helps. The Init solution doesn't work for what I want to do though.

I will try to compile the latest version.

No need (unless you really want to) - it's in the Marketplace and the github release list now.

Oh, awesome!

I gave compilation a quick shot but there were some problems. However I haven't yet read the Contributing article so I'm probably missing something. I'll leave that for another time since I have no urgency now.

Thanks
