 ## .NET
 
-EF Core is a .NET library. EF Core version 8.0 targets .NET version 8.0, while both EF Core versions 6.0 and 7.0 target .NET version 6.0. In general, we target the latest [LTS release](/lifecycle/products/microsoft-net-and-net-core) of .NET. This enables you to upgrade to a newer, STS release of EF Core to take advantage of the latest features without having to upgrade your entire app. There may be exceptions to this, however, as runtime features sometimes get added that require us to depend on the latest version of .NET.
