Excel DNA packing issue

Question

I am trying to pack all my dlls into XLL using the ExcelDNApack.exe, for this I am using below command and its generating pack xll file for me.

"$(SolutionDir)dependencies\Excel-DNA.0.32.0\tools\ExcelDnaPack.exe" 
"$(TargetDir)ExcelTrader-AddIn.dna" /Y

But when I am running the xll file from the folder where I dont have dependent dlls its throwing an exception "An Exception occured while calling function OnLoad". The exception message is Could not load file or assembly 'OpenApiSecurityLib, version=1.0.0.0,Culture=neutral,PublicKeyToken=null'

I have a main project ExcelTrader.dll which references OpenAPISecurityLib.dll and OpenAPIClientLib.dll, I have added Reference attribute in the dna file for both these dlls and dependencies and added ExternalLibrary attribute for ExcelTrader.dll

If I put both OpenAPISecurityLib.dll and OpenAPIClientLib.dll in the same folder as xll file, XLL file runs perfectly fine

Please suggest what is that I am doing wrong here Thanks

Answer 1

My issue got resolved I checked that in the output 'Reference with Path: System.Threading.Tasks.Dataflow.dll and Name: not found.' after this exception rest of the references were getting ignored.

I checked that the dll reference for which the error was coming is no more in use in our project after removing reference for this dll everything worked fine.
