 > [!IMPORTANT]
 > The guidance in this article applies only to [C# class library functions](functions-dotnet-class-library.md), which run in-process with the runtime. This custom dependency injection model doesn't apply to [.NET isolated functions](dotnet-isolated-process-guide.md), which lets you run .NET functions out-of-process. The .NET isolated worker process model relies on regular ASP.NET Core dependency injection patterns. To learn more, see [Dependency injection](dotnet-isolated-process-guide.md#dependency-injection) in the .NET isolated worker process guide.
