libsdkencryptedappticket cannot be loaded on Linux

[LukasTr]

I'm using Steamworks.NET in C# with ASP.NET Core.

I am using the encrypted app ticket features, and running the app on Amazon Linux. According to the documentation, this requires sdkencryptedappticket.so to be placed next to libsteam_api.so .

I added both files to the project, and configured them to "copy to output". Unfortunately, this isn't working. Here's the error message:

DllNotFoundException: Unable to load shared library 'sdkencryptedappticket' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libsdkencryptedappticket: cannot open shared object file: No such file or directory

I attempted to solve this using patchelf to set a soname as described here, but this didn't work either.

Is this a known problem?
