.NET 4.7.1 support

[johnkors]

Similar to #1488 , but for 4.7.1.

I assume it is related to "Visual Studio 2017 Preview" image where we should install VS 2017 15.5 with .NET 4.7.1 targeting support?

[johnkors]

Hm, I'm just using the dotnet sdk directly, and that worked even in the 2015 image. But yeah - I guess it relates to both the 2015 and 2017 appveyor images..?

[jp2masa]

The .NET Framework 4.7.1 targeting pack can be installed separately, but VS 2017 15.5 will include support to target .NET Framework 4.7.1 without any additional installation.

@FeodorFitsner are there any docs about the "Visual Studio 2017 Preview" image?

[waynebrantley]

@FeodorFitsner You can just install 4.7.1 sdk on the normal image. Should have no impact.

[tompazourek]

I know it's only been like 2 weeks since it's been released, but is there some expected time frame for when we could start using .NET 4.7.1 with AppVeyor?

[FeodorFitsner]

It's scheduled to the "next images update" milestone which is going to be end of this or next week.

[waynebrantley]

@FeodorFitsner Is this still expected this week sometime?

[FeodorFitsner]

Yearly next week.

One naive method is:

"C:\Program Files\Git\mingw64\bin\curl" -O https://download.microsoft.com/download/9/0/1/901B684B-659E-4CBD-BEC8-B3F06967C2E7/NDP471-DevPack-ENU.exe

NDP471-DevPack-ENU.exe /q /norestart

exit /B 0

and execute this batch file on before_build hook.

[waynebrantley]

@FeodorFitsner Any chance of getting this ASAP?

[FeodorFitsner]

Images are being tested right now. Will deliver them tomorrow or early Friday.

Currently prevents me from using a .NET Standard 2.0 DLL in PowerShell: https://github.com/PowerShell/PowerShell/blob/master/docs/cmdlet-example/command-line-simple-example.md#using-a-net-standard-20-based-binary-module-in-windows-powershell

@wongsyrone your workaround didn't work for me unfortunately

It's expected. The installer requires rebooting your system to take effect. But if you do reboot, boom, everything is gone. That's why I add /norestart to the cmdline. And use exit /B 0 to cheat the CI to ignore any ERRORLEVEL set by the installer. If you do check the error code, it means you have to reboot your system.

In fact, the installer installs two components: runtime and develop modules. I just need develop modules.
