Something failes to load when deploying MirrorSharp on a server

[Sicos1977]

When I run my project in visual studio 2022 I have no problems but when deployed on IIS on a Windows 2019 server something failes to load. Does somebody know how I can hook into MirrorSharp to find out what is failing to load. I have no idea how I can retrieve the LoaderExceptions property

Well it seemed to be an assembly redirect in the app.config file from the service that is hosting mirrorsharp. It was pointing to a deleted assembly version

Still it would be nice if there was a way to hook into the exception to retrieve some more information. This time I found it rather quick but the exception that is shown in the eventviewer is very difficult to read.

Thanks for reporting! It's a fair point -- I could actually expose assembly name and LoaderExceptions directly for this one.
I'll look into this (no specific timeline promise).

Any updates on this?

Not yet, I haven't actively looked at the library for a while, but might take a look as part of the new upgrade work (no promises).
