Hello everyone,

In the software that I created with Keyence image sensors, I run a .dll file and import the data from FTP to my program. In this software I created with Windows10 .Net Framework 4.8, the target version of the .dll file is 4.0.0. My program works fine on Windows 10, but it throws "FileNotFoundException" error with IoT Core computer. You can find the image of the error attached. Thank you in advance for your help.

Best regards,

    Welcome to Microsoft Q&A!

    Could not load file or assembly 'Keyence.IV2.Sdk.Lib.dll' or one of its dependencies. The specified module could not be found.
