[mletterle]

Tool information

The image already includes the non-LTS .NET 2.0 SDK, it should also include the LTS 2.1 SDK/Runtime

Area for Triage:
.NET Core

Question, Bug, or Feature?:
Bug

Virtual environments affected

• [X] macOS 10.15
• [ ] Ubuntu 16.04 LTS
• [ ] Ubuntu 18.04 LTS
• [ ] Windows Server 2016 R2
• [ ] Windows Server 2019

Can this tool be installed during the build?
Yes, it can, but it shouldn't have to be.

Tool installation time in runtime
Not Long

Are you willing to submit a PR?
I would but the macOS source isn't available yet.

Thanks for the suggestion @mletterle.

@maxim-lobanov, should we get rid of 2.0?

[maxim-lobanov]

Yep, we should but we need to do some announcement here. I will take care about it.

[maxim-lobanov]

Oh, just found that .NET Core 2.0 is installed to fix some legacy compatibility issue related to miniconda. Need to check if it can be safety removed.

Also will install .NET Core 2.1 to macOS 10.15 images
