How to load as assembly for SSRS?

[forslundscott]

I have watched several tutorials on loading the .dll to SSRS as an assembly, but when I try with this library I keep getting and error reading, " Could not load file or assembly 'QRCoder". It also says "Failed to grant permission to execute. (Exception from HRESULT: 0x80131418)". The errors occur at "SetReportDefinition" and "SetItemDefinition" in SSRS. Does anyone know the solution to this? I need this for something for work by year end. Any help would be much appreciated!

Thank you!

This is the full error text:

Have you set the permissions as explained here: https://social.msdn.microsoft.com/Forums/en-US/9955d507-a028-4b67-8cd7-f6586832f5fc/problem-in-running-ssrs-report-using-custom-dll-in-ssrs-2016-failed-to-grant-permission-to-execute?forum=sqlreportingservices ?

Thank you. Now I have that working, but I cannot figure out how to write a vb code in SSRS that can properly use this dll. Any insight on how to write a vb function that will result in a qrcode image from this dll?

Nevermind, I found #336 which references #337 which helped get it working. Thank you for a great tool and good discussion response!
