回答1:
This is not a supported scenario by ExcelDnaPack at the moment.
ExcelDnaPack only supports packing of .NET assemblies (a.k.a. managed DLLs). sqlceca40.dll is a Win32 DLL... Therefore you won't be able to pack that DLL in your XLL using ExcelDnaPack.
You could use alternative approaches to embed the sqlceca40.dll into your add-in assembly using a tool such as Fody.Costura, for example, as this example in SO shows.
