VSTS Build Error – Not compatible with netcoreapp2.0

I recently setup a new VSTS CI build for a .NET Core project which initially threw an error during the Nuget Restore step:

The nuget command failed with exit code(1) and error(Errors in C:\agent\_work\2\s\Acme.Function.App.Client\Acme.Function.App.Client.csproj
Project Acme.Function.Model is not compatible with netcoreapp2.0 (.NETCoreApp,Version=v2.0). Project Acme.Function.Model supports: netstandard2.0 (.NETStandard,Version=v2.0)
One or more projects are incompatible with .NETCoreApp,Version=v2.0.)

Packages failed to restore

I eventually found a couple blog posts which said I needed to use version 4.3 of Nuget.  Sure enough the logs indicated it was using version 4.1:

2018-06-10T18:47:36.3507543Z Found tool in cache: NuGet 4.1.0 x64
2018-06-10T18:47:36.3508209Z Found tool in cache: NuGet 4.1.0 x64
2018-06-10T18:47:36.3508638Z Resolved from tool cache: 4.1.0
2018-06-10T18:47:36.3508768Z Using version: 4.1.0

So first I looked at how to update Nuget on a server which didn’t really yield any good results.  And then I remembered I had a Nuget Installer task in my other pre-existing.

After adding the Nuget installer task my Nuget Restore finds the new version and works correctly:
