Since this issue was created, v3.0.0-preview5 has been released.
Is this issue specifically about preview2 or more generally about the newest available preview?

v3.0.0-preview6 has also been released now

@FeodorFitsner We're starting to migrate some code to netstandard2.1 / netcoreapp3.0. Could you go ahead and push this through on the VS2019 Preview image? Is there anything preventing its installation?

@IlyaFinkelshteyn Do AppVeyor images provide the dotnet-install.ps1/dotnet-install.sh scripts? This would make it very easy for users to install whichever .NET Core version they need as part of their build, without you guys having to update the image for every new preview version.

[FeodorFitsner]

The required version of .NET Core could be easily installed with these one-two liners.

On Windows:

Invoke-WebRequest -Uri 'https://dot.net/v1/dotnet-install.ps1' -UseBasicParsing -OutFile "$env:temp\dotnet-install.ps1"
& $env:temp\dotnet-install.ps1 -Architecture x64 -Version '<CORE_SDK_VERSION>' -InstallDir "$env:ProgramFiles\dotnet"

where CORE_SDK_VERSION is .NET Core SDK version to install, for example 3.0.100-preview6-012264.

On Linux:

wget -O dotnet-sdk.tar.gz <CORE_SDK_LINUX_URL>
sudo tar zxf dotnet-sdk.tar.gz -C /usr/share/dotnet

where CORE_SDK_LINUX_URL is a download URL of .NET Core Linux binaries from .NET Core download page. You can grab "click here to download manually" link from "Thanks for downloading" page.

perhaps should be closed in favor of #3098 ?
