I'm getting below error in log file when trying to start the .Net Core API application deployed on IIS. Tried many workarounds according to many posts (configuration changes in IIS, etc) but still couldn't resolve this issue. Specially tried to add logs to find specific missing dlls using this link, related to .Net Core ReflectionTypeLoadException in ASP.NET Core MVC application
But it didn't log any specific log message related to this exception. Only the above mentioned error is there in the log.
This is a .Net Core API application (Net Core 2.0 with Visual Studio 2017). Deployed on IIS in both Windows 10 & Windows Server 2012 R2. Same error is there in log file.
Main issue I found here is: this project has added a reference to a SOAP service (asmx service). When this service reference is removed, no such error. Seems the application is trying to get relevant dlls from some where else, instead of getting from published folder. May be from GAC. But copied the dlls related to "system.servicemodel.*" to GAC as well (these are the automatically added dlls (from Nuget) when adding that service reference via Connected Services in Visual Studio).
This happens only after deployed (on IIS). When runing this application from source code, this works fine. No such error. I'm not sure if these new version of .Net Core doesn't support asmx services after deployed.
Appreciate any help to resolve this issue, as we need that asmx service reference in this project. Thank you.
