如何在 Entity Framework db-first 项目中添加非聚集索引？

Question

I have a table in SQL Server which includes custom nonclustered indexes for some columns. And I have also a project with below versions.

• .Net Framework 4.6.2
• Entity Framework 6.4.4

I added an entity data model to project based on my existing database (using a database-first approach).

Although a SELECT query returns quickly in database, the same query gets a timeout error in the project. And I thought that EF couldn't add column indexes to the project. I searched index names in the project, but there isn't any code about indexes in the project.

So, how can I add indexes to my database-first model?

"database-first" means that you apply design changes to the database first , and then apply any changes to the EF model second.

So you just create the indexes in SQL Server using Visual Studio or SSMS , and since EF model doesn't need to change when you add an index, you're done.
