Example VB.NET visual studio project creating a COM DLL for use in Excel VBA

I need a Visual Studio 2019, VB.NET project compiled for .net Framework 4.0 that builds a simple COM DLL containing a single class "Hello World" with a single method "SayIt" that returns the string "Hello World". THen I need detailed procedures for exactly how to distribute and register that DLL on another workstation and adding it to an Excel VBA script that will display a message box showing the string returned form the DLL method
