Fix up "Unable to resolve dependency Microsoft.Web.Xdt" when adding nuget

Problem

This happened when I was adding "ComponentHost" nuget from the Cerebro repo.

Solution

Click on Tools > NuGet Package Manager > Package Manager Console

$>  Install-Package Microsoft.Web.Xdt

That is it !

Alternate Problem
