How to change a clustered index in Entity Framework 6.1 Code First model and apply it to an Azure database

Question

Using the Entity Framework 6.1 code first model, what is the best way to go about changing the clustered index on a table from the default ID to another set of columns. Azur

This is truly an area where EntityFramwork (Core) had to advance and it still is hard.

So, I could not use IsClustered(false) for my GUID / string Primary keys, for the simple reason, the project having DbContexts was DB - agnostic. So you needed to Add EntityFrameworkCore.SqlServer and IsClustered is available then, and only.

So, my solution was simple. Add no nuget package but this attribute. This ONLY works on EF Core.

I have tested this on SQL. Though, not sure if the other providers would allow this string not having any meaning. (e.g. SQLite does not know clustered indexes)

 p.HasKey(k => k.Id).HasAnnotation("SqlServer:Clustered", false);
