@mhosman - can you clarify the repro steps....

I not sure how to do this: "Update from 2.0.5 to 2.1.0-preview-final using NuGet Administrator (Preview releases included)."
what is NuGet Administrator? etc...

@mhosman - which type of app were you trying to upgrade?? When I try this with a asp.net core 2.0 app, it starts with:
<PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.0" />

However, if I create a new Asp.net core 2.1 app, it has the following package in it:
<PackageReference Include="Microsoft.AspNetCore.App" Version="2.1.0-preview1-final" />

updating the Microsoft.AspNetCore.All to 2.1.0-preview1-final didn't work properly...restore fails.
However, if you change your targetframework to netcoreapp2.1 first, it seemed to succeed.

Would love to understand the exact scenario you were trying...

From asp.net team...need to change targetframework from netcoreapp2.0 to netcoreapp2.1 if you want to use 2.1 packages.

NuGet has a backlog task to improve search and update to only show compatible packages...this experience will improve then.
