Entity Framework: how to solve “FOREIGN KEY constraint may cause cycles or multiple cascade paths”?

Introducing FOREIGN KEY constraint 'FK_dbo.ChildProfile_dbo.SourceType_SourceTypeId' on table 'ChildProfile' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.
Could not create constraint. See previous errors.

Also you can modify your migration class. In my case in the migration class was:

Make  "cascadeDelete: false" Update-Database works perfectly.


OR
Add this code in context

protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();
    }

Update-Database works perfectly.
