Possibly related to ASP.NET Core 2.0 Could not load file or assembly System.ServiceModel
We are currently developing a console app using .NET Core 2.0 as framework that references a .NET Framework 3.5 WCF library.
When we execute the console app an error appears in the debug output:
Could not load file or assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. The system cannot find the file specified.
What do we have to do to get this assembly visible to the Dotnet Core 2.0 console app?

I am getting below errors while trying to build/publish a blazer application (client version) in release mode. The application is running fine and is getting published as well in debug mode.
Unhandled exception. Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: 'ExistingLibraryBuiltIn.NetFramework4.7.1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' C:\...\.nuget\packages\microsoft.aspnetcore.components.webassembly.build\3.2.0-rc1.20223.4\targets\Blazor.MonoRuntime.targets 284
ILLink failed with exit code -532462766.
Project Details -
VS Version - 16.7.0 Preview 2.0,
Target Framework - .Net Standard 2.1
Is it even possible for a .Net Core 2.1 console application to reference a .Net Framework 4.6.1 DLL?
I have such a DLL that consumes a WCF service successfully. I now wish to use this DLL from a .Net Core 2.1 console application. But I am getting an exception stating that it cannot load assembly System.ServiceModel. The web.config file in the 4.6.1 DLL has relevant settings for System.ServiceModel.
Many thanks.
I am creating a fresh ASP.net core web API.
I have referenced a project DLL in my web API which is again referring to system.web.application.services.dll.
The solution is building fine but getting the below exception when I call POST verb from POSTMAN.
Error details:
Could not load file or assembly 'System.Web.ApplicationServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified
It sounds like you're referencing a .NET Framework 4.6 (or below) DLL in your .NET Core project. You have two options:
Add a reference to System.Web.ApplicationServices in your project. You may have to browse for the actual DLL (System.Web.ApplicationServices.dll), which you should be able to find in C:\Windows\Microsoft.NET\Framework64\v4.0.30319.
(I think this will work) Change your project to target the full .NET Framework instead of .NET Core.
You might run into other roadblocks after doing this, but it's a step in the right direction.
I have an ASP.NET Core 1.1. web application and I have successfully referenced it to a .NET 4.6 class library.
When a call is made from one of the web application's controllers to one of the public methods of .NET 4.6 class library I am getting the following exception:
"Could not load file or assembly 'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. The system cannot find the file specified."
Any ideas, how I can correct that?
when I add a .NET core class library dll to my ASP.NET core project and try to use it in my code, I get the following:
FileNotFoundException: Could not load file or assembly
'Test.Core, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=null'. The system cannot find the file specified.
I'm on .NET Core 1.1 for both projects. The dll is referenced in the project. I assume I need to add the reference of this class dll in some config file but I searched everywhere and couldn't find where.
Any help would be appreciated

Until they fix the issue in 1.1, if possible, if you jump back to 1.0 this should not be a problem as i can get it working fine on 1.0.
