How to drop unique index with entity framework code first migrations

Question

I\'m using Entity Framework 5.0 with Code First migrations enabled.

I\'ve added Unique key by using:

CreateIndex(\"dbo.Groups\", \"Name\", true);
         


        

Answer 1

Ok, I solved this on my own :)

Apparently I misused syntax for DropIndex. I assumed it takes name of column, but instead it takes name of index. This worked:

DropIndex("dbo.Groups", "IX_Name");

:)

Answer 2

There is another answer to this:

DropIndex("dbo.Groups", new[]{"Name"});

There is an overload of DropIndex that takes column names, but it takes an array of them. So for a single column name you still have to wrap it in an array to get to the overload.
