Thanks for your guidance and valuable time.
my question is where to copy external dlls which are used in ssrs references, for example to get barcode/Q.R. printed in ssrs. that process for earlier vversions of visual sttudio is known to me. only vs2022 the report project is not fiinding them when i try to preview report from vs2022 preview option. other wise that report in application is running well , the required libraries in bin directory of application works well.
just to remind all here that diffrent locations fo copy dlls were as under
echo Barcode.dll File Copied Paths
