JavaScriptEngineSwitcher.V8 NuGet package incompatible with .NET Core

[Zenexer]

I'm attempting to use V8 with .NET Core 2.1. ChakraCore works, more or less, but whenever I try to use V8:

System.MissingMethodException: Method not found: 'System.AppDomainSetup System.AppDomain.get_SetupInformation()'.
   at JavaScriptEngineSwitcher.V8.AssemblyResolver.AssemblyResolveHandler(Object sender, ResolveEventArgs args)
   at System.AppDomain.InvokeResolveEvent(ResolveEventHandler eventHandler, RuntimeAssembly assembly, String name)

System.IO.FileLoadException: Could not load file or assembly 'ClearScriptV8, Culture=neutral, PublicKeyToken=null'. Method does not exist. (Exception from HRESULT: 0x80131513)

I noticed that I get a warning for the JavaScriptEngineSwitcher.V8 NuGet dependency:

Package 'JavaScriptEngineSwitcher.V8 2.4.13' was restored using '.NETFramework,Version=v4.6.1' instead of the project target framework '.NETCoreApp,Version=v2.1'. This package may not be fully compatible with your project.

Sure enough, the NuGet package requires .NET Framework v4.0 or v4.5:

Am I correct in assuming that JavaScriptEngineSwitcher.V8 is incompatible with .NET Core?

Hello, Paul!

Am I correct in assuming that JavaScriptEngineSwitcher.V8 is incompatible with .NET Core?

Yes, you understood correctly. There is even a note in the README.md file:

• JS Engine Switcher: V8 (supports .NET Framework 4.0 Client and .NET Framework 4.5)

JavaScriptEngineSwitcher.V8 module is based on the Microsoft ClearScript.V8 library that is not yet compatible with .NET Core.

FYI: V8.Net is now .Net Standard (core) compatible.
