I am facing a issue related to subgurim maps. I downloaded a sample from offical subgurim map github repository. It works as expected because running on 3.5 version but if I upgraded to 4.7.2 or above 4 version. Gives me the error screenshot is attached below.
Error invisible to.

1. I don’t have code access of Subgurim maps library. So, I can’t make any changes related to InvisibleTo in the source code. Nuget package link
2. I tried reflection technique to ressolve the issue becauase code throws MethodAccessException but no luck.
3. I made changes in web.config underneath of runtimes, because I am successfully able to get the public token 564d55b144e7aa5a.
