ASP.NET Core targeting net461 in Azure - asp.net-core

Question

Can an ASP.NET Core project target net461 and run on an Azure Website?
Here is what have been tried and failed.
It works when targeting netcoreapp1.0 but when I change it to net461(including some other needed changes to compile) I get the following error:
Unhandled Exception: System.TypeInitializationException: The type initializer for 'Microsoft.Extensions.PlatformAbstractions.PlatformServices' threw an exception. ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.AppContext, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

Specifically
System.IO.FileNotFoundException: Could not load file or assembly 'System.AppContext, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
Locally it works fine.
I've naively added nuget packages to include the needed assemblies.
{
"dependencies": {
"Microsoft.AspNetCore.Diagnostics": "1.0.0",
"Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",
"Microsoft.AspNetCore.Server.Kestrel": "1.0.1",
"Microsoft.AspNetCore.StaticFiles": "1.0.0",
"Microsoft.Extensions.Logging.Console": "1.0.0",
"Newtonsoft.Json": "9.0.1",
"System.AppContext": "4.1.0",
"System.Reflection.TypeExtensions": "4.1.0",
"System.Security.Cryptography.X509Certificates": "4.1.0"
},
Eventually I got a different kind of errors:
warn: Microsoft.AspNetCore.Server.Kestrel[0]
Unable to bind to http://localhost:7762 on the IPv6 loopback interface.
System.AggregateException: One or more errors occurred. ---> Microsoft.AspNetCore.Server.Kestrel.Internal.Networking.UvException: Error -4089 EAFNOSUPPORT address family not supported

I'm not sure where to go from here.

Although the publish profile had the option checked to "remove additional files at destination" there must still have been some files left.
Using FTP and manually delete all files before publishing solved the project.
ASP.NET Core targeting net461 works on Azure assuming you have not published any other frameworks there previously.
These NuGet packages I added in the question was not needed either and can safely be removed from the project.
"System.AppContext": "4.1.0",
"System.Reflection.TypeExtensions": "4.1.0",
"System.Security.Cryptography.X509Certificates": "4.1.0"
