Index on Spatial / DBGeography Property for Entity Framework Code First

Question

I have an EF (6.1) code first project and one of its model has a DbGeography Property (which will contain only POINT geographies) which I'll perform queries against.

I declare custom indices following the official guide, however it is lacking details regarding indices for spatial members / properties and I was wondering how I can create those via Code First?

The underlying Database is / will be SQL Server 2012 if that plays any role.

Could not comment.

Practically same question here.

Apparently it cannot be done.
