Microsoft Report Designer - Undocumented Error could not load file or assembly... RRS feed

  • Question

  • I have recently started to get this error when trying to add a dataset to an RDLC.  I have searched all over the internet for a solution to this problem and have not found it.  There is one other person on this forum who had my same issue, and I tried what he did, and it did not work for me.

    What I do to get this issue, is create a report and then hit the new button in the tool box and then select dataset.  This error then pops up immediately "Undocumented Error.  Could not load file or assembly 'App_subcode_pscoredll.rnecvofk, version =, culture = neutral, publickeytoken=null' or one of its dependencies.  the system cannot find the file specified."

    This is an urgent issue for me as we need to complete this report.
