 > 💡 Still on Entity Framework 6 (non-core)? Then [QueryableValues `EF6 Edition`](https://github.com/yv989c/BlazarTech.QueryableValues.EF6) is what you need.

-The `AsQueryableValues` extension method is intended for queries that are dependent upon a *non-constant* sequence of external values. It provides a solution to the following [EF Core issue](https://github.com/dotnet/efcore/issues/13617) and enables other currently unsupported scenarios; like the ability to efficiently create joins with in-memory data.
