title: EF Core Data Seeding (HasData method on modelBuilder) not inserting data for Identity column
body: <p>I'm calling the HasData method (see below) for an entity that has an Id (Identity) column, but no data is inserted into the table the first time the Migration runs.</p>
  <p>When the TestObject model was not using an Id (Identity) column for the Primary Key, data was inserted as expected the first time the migration was run.</p>
  <p>Is EF Core able to insert data for Identity columns?</p>
  <pre><code>modelBuilder.Entity&lt;TestObject&gt;().HasData(
              new TestObject
              {
                  Id = 1,
                  TestValue = &quot;Test 1&quot;
              }
  </code></pre>
