YES, you can - use native DLLs in your Azure Functions via P/Invoke ([DllImport]) as you already know it from .NET Framework, and safe the code you have developed and maintained for decades with much effort and patience.

Illustrated guide on how to integrate a native DLL into Azure Functions. I use Visual Studio 2019, .NET Core 3.1 and .NET SDK Functions 3.0.3 for the managed DLL that contains the Azure Functions. I add a Pre-build event command line to the C# Azure Function project that copies the native DLL into the source code folder of the C# Azure Function project.
