CodePudding user response：

The answer here lies in - BadImageFormatException. One of these

Your app is compiled for one architecture (x64 or x86) but your Web Server pool runs different one
One of the 3rd party DLLs is of incompatible architecture (your case)
One of your DLLs is of incompatible architecture.
DLL is compiled for the wrong platform. e.g. running DLL compiled for .net4.8 in the .netcore (your case)
