EntityFramework code first: Set order of fields

Update: In EF Core 2.1, for the initial migration at least, columns are added to tables in the order in which the relevant properties are declared in their respective classes, rather than in alphabetical order. See here. But note that any subsequent Entity Framework migrations performed on the same tables won't change the column order of the columns created earlier.

Currently ordering columns by class property is not implemented. Here's the long discussion about column ordering. Column ordering #2272

Update as of 07/12/2017

This issue is in the Backlog milestone. This means that it is not going to happen for the 2.0 release. We will re-assess the backlog following the 2.0 release and consider this item at that time.

Update as of 06/10/2019

Issue 2272 shipped with EF Core v2.1 and matches the order of the columns in the generated table to the order of the properties in the class. However, as @lloyd-conrade mentioned, this is only useful for initial creation

A new issue, #10059, has been created to track the possible implementation of respecting the Column attribute's Order property.

If the implementation of #2272 is insufficient for you and specifying something like [Column(Order = 1)] would help, please vote for this issue and add details about your scenario (if not already listed) below.

Note the "Punted for 3.0" label was added on May 10th, 2019, which is to say it will not ship in EF Core 3.0.
