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

Answer 1

You need to remove the existing clustered index from your current PK 'ID' which is created by default for any "KEY" property in code first. It can be done using fluent API:

.Primarykey(x=>x.ID,clustered:false)

Once existing clustered index is removed from ID, your migration to add the clustered index on UserID should run smoothly.
