1.0.3 - first-run experience should work even with a 2.0 CLI installed.

Steps to reproduce

1. Cleared NuGet caches (dotnet nuget locals all --clear).
2. git clone https://github.com/aspnet/DotNetTools.git --branch rel/1.0.1 && cd DotNetTools
3. Change global.json to sdk 1.0.3
4. dotnet restore

Expected behavior

First-run experience primes nuget cache and restore works.

Actual behavior

First-run fails with

Failed to create prime the NuGet cache. restore failed with: 1

All calls to dotnet restore fail regardless of DOTNET_SKIP_FIRST_TIME_EXPERIENCE setting

/Users/namc/.dotnet/sdk/1.0.3/NuGet.targets(97,5): error : Failed to retrieve information about ‘Microsoft.NETCore.App’ from remote source ‘/Users/namc/.dotnet/NuGetFallbackFol der’. [/Users/namc/dev/aspnet/DotNetTools/DotNetTools.sln]

Environment data

dotnet --info output:

.NET Command Line Tools (1.0.3)

Workaround

export DOTNET_SKIP_FIRST_TIME_EXPERIENCE=1
mkdir -p ~/.dotnet/NuGetFallbackFolder

Yes, restore works fine if I mkdir -p ~/.dotnet/NuGetFallbackFolder or edit the global NuGet.config.

NuGet cache warm is still broken though. It appears once you install a 2.0.0-* version of CLI, NuGet cache warmup on 1.x CLI breaks.

Repro: Install 2.0.0-preview1 and 1.0.3 CLI. Set global.json to 1.0.3. dotnet new

Result: As above: “Failed to create prime the NuGet cache.”

This looks like a duplicate of what’s described here: https://github.com/dotnet/cli/issues/6381

I believe this is actually a dup of this one here: https://github.com/dotnet/cli/issues/6550. I will track this issue there, as it has a better explanation of what is going on.
