.NET Core Tools Telemetry
--------------
The .NET Core Tools include a telemetry feature that collects usage information. It is important that the .NET Team understands how the tools are being used so that we can improve them.

The data collected is anonymous and will be published in an aggregated form for use by both Microsoft and community engineers under the Creative Commons Attribution License.

The .NET Core Tools telemetry feature is enabled by default. You can opt-out of the telemetry feature by setting an environment variable DOTNET_CLI_TELEMETRY_OPTOUT (for example, 'export' on macOS/Linux, 's
et' on Windows) to true (for example, 'true', 1). You can read more about .NET Core tools telemetry at https://aka.ms/dotnet-cli-telemetry.
Unsupported use of '||'. In fish, please use 'COMMAND; or COMMAND'.

Therefore this package is definitely broken, if you use shell scripting you should not guess what shell users have! This is poor and dangerous…

@livarcocc this is still an issue, thank you for treating it the microsoft way! @wli3 with chsh -s /usr/bin/fish, and than start a new shell, or re-login, you just need to make sure that you have switch to your new environment, after changing your user’s default shell.
