Missing .NET Core version of AppVeyor logger for vstest.console

[jariq]

I am using Visual Studio 2017 image and I tried to run my tests with .NET Core and its vstest.console with the following command:

C:\projects\pkcs11interop>dotnet vstest .\src\Pkcs11Interop.NetStandard\Pkcs11Interop.DotNetCore.Tests\bin\Release\Pkcs11Interop.DotNetCore.Tests.dll /logger:AppVeyor
Microsoft (R) Test Execution Command Line Tool Version 15.0.0.0
Copyright (c) Microsoft Corporation.  All rights reserved.

Could not find a test logger with URI or FriendlyName 'AppVeyor'.

Seeing that vstest.console included with .NET Core SDK 1.0.4 was unable to find AppVeyor logger I decided to shamelessly copy Appveyor.BuildAgent.Api.dll and Appveyor.MSTestLogger.dll from VS2017 installation with following command:

copy "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\CommonExtensions\Microsoft\TestWindow\Extensions\AppVeyor*" "C:\Program Files\dotnet\sdk\1.0.4\Extensions"

After that vstest.console was able to find the logger but displayed exception anytime the logger was used:

C:\projects\pkcs11interop>dotnet vstest .\src\Pkcs11Interop.NetStandard\Pkcs11Interop.DotNetCore.Tests\bin\Release\Pkcs11Interop.DotNetCore.Tests.dll /logger:AppVeyor
Microsoft (R) Test Execution Command Line Tool Version 15.0.0.0

Starting test execution, please wait...

Problem can be seen in this sample build. I am guessing that AppVeyor logger for vstest.console needs to be rebuilt for .NET Core. Please let me know if I can help with that.
