Hi,
I suddenly started getting the following exception when compiling any report: Cannot create an abstract class
This happens in a server and don't happens on another server (the same application).

This is urgent, please advice.
I updated .NET 5 on both servers and also try with an empty report.
Continue to work on one server and did not work on another.
I can't find stimulsoft .NET source code on my account to download and check deeper inside CompileAsync method.
Another point: All my reports came from a string with the report xml file: LoadFromString

I just found that this issue is related with the ZXing.Net.Bindings.CoreCompact.System.Drawing that was added to the project yesterday.
ZXing uses CoreCompact.System.Drawing.v2 and Stimulsoft uses System.Drawing.Common. Probably came from here the issue even don't happen in development environment and happen on one server and not another.

You can close this issue.
I found an alternative to ZXing.Net.Bindings.CoreCompact.System.Drawing and the incompatibility was workarounded.
