When using Code-First approach, how do you create an index that spans multiple columns?
- Using Fluent API's HasIndex method
- Using the Index attribute with Include properties parameter
- Using the Index attribute with Name parameter
- Using the Key attribute with Index parameter
When using the Code-First approach in Entity Framework, you create an index that spans multiple columns using Fluent API's HasIndex method. This method allows you to define an index on multiple columns by specifying the properties involved in the index. Using Fluent API provides more flexibility and control over index creation compared to using attributes like Index or Key.
