Hello,
I’m new in active reports and i am trying to print a report in a asp.net 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=4.0.0.0, 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="403">Forbidden</response>
/// <response code="404">Not Found</response>
/// <response code="500">Internal Server Error</response>
/// <returns></returns>
