Could not load file or assembly 'Merged' or one of its dependencies

I am trying to start an iis site (asp.net mvc) which has worked perfectly before my changes. I have referenced some nuget-packages (nothing special, but some of them reference netstandard) and have done some minor code changes. Now I am getting the error Could not load file or assembly 'Merged' or one of its dependencies with this stacktrace while trying to connect to the site:

I also provide assembly binding logs:

I have looked around trying to find the dll with the name "Merged". But it seems to be partial assembly name. Also it looks like this error is thrown before my actual code starts. I tried restoring packages. Also it works fine on local machine, but on the other server it fails.

How can I fix this error?

So finally I figured it out. The problem was that one of the packages that I've installed took the netcoreapp dependency. But my application is netframework. So none of this netcoreapp library dependencies was put to the binary directory and this library could not be loaded. I found this Merged.dll in my app's binary folder and removed it. After that it works.

Now I am in contact with this package authors to find out why netcoreapp dependency was put in netframework app.
