SqlMethods.Like equivalent in EF7

In EF6, we can perform a SQL LIKE enquiry by writing

SqlMethods.Like(dbProductMaster.ProductName.ToLower(), "%" + searchProductName.ToLower() + "%"))

and it will translate to

SELECT * FROM ProductMaster WHERE ProductName LIKE '%xxx%'; 

What should I do to perform the same query under EF7?

EF.Functions.Like() is here in EF Core 2.0 by the way
