    I’m new in active reports and i am trying to print a report in a web api in .net 5. I have managed to render a report and get back as a pdf when doing a get request. When i want to print te same report i get the following exception.

    “message”: “Could not load file or assembly ‘System.Resources.Extensions, Version=, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’. The system cannot find the file specified.”,

    “type”: “System.IO.FileNotFoundException”,

    Don’t know if it has anything to doe with it but:

    When in debug mode i see that the pagedocument.IsEmpty throws an exception of type InvalidOperationException.

    Here is the used code

        /// <summary>
        /// Get all report categories.
        /// </summary>
        ///// <param name="id"></param>
        ///// <param name="queryParameterString"></param>
        /// <param name="ct"></param>
        /// <response code="200">Ok</response>
        /// <response code="400">Bad Request</response>
        /// <response code="401">Unauthorized</response>
        /// <response code="403">Forbidden</response>
        /// <response code="404">Not Found</response>
        /// <response code="500">Internal Server Error</response>
        /// <returns></returns>

    The problem is already solved, an Package reference was missing.

    I am having the same issue - what package did you need to add?

    Hi Mike,

    This seems to be a generic issue. As per the error message the package “System.Resources.Extension” is not found. I would suggest you to try adding this package to your project and refer to the following post on the StackOverFlow Forum page:

    If the issue persists then please share a sample application reproducing this issue so we can reproduce this issue at our end and get back to you accordingly.
