After adding the FlurlHttp Nuget package to my PCL project my app will no longer deploy to my emulator due to an assembly loading error

Error Exception while loading assemblies: System.IO.FileNotFoundException: Could not load assembly 'PCLStorage.Abstractions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=286fe515a2c35b64'. Perhaps it doesn't exist in the Mono for Android profile? File name: 'PCLStorage.Abstractions.dll' at Xamarin.Android.Tuner.DirectoryAssemblyResolver.Resolve(AssemblyNameReference reference, ReaderParameters parameters) at Xamarin.Android.Tasks.ResolveAssemblies.AddAssemblyReferences(ICollection1 assemblies, AssemblyDefinition assembly, Boolean topLevel) at Xamarin.Android.Tasks.ResolveAssemblies.AddAssemblyReferences(ICollection1 assemblies, AssemblyDefinition assembly, Boolean topLevel) at Xamarin.Android.Tasks.ResolveAssemblies.AddAssemblyReferences(ICollection`1 assemblies, AssemblyDefinition assembly, Boolean topLevel) at Xamarin.Android.Tasks.ResolveAssemblies.Execute() InfoSupport.AV.MobileClient.Droid C:\Program Files (x86)\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets 1347

The build system is also reporting conflicts :

There was a conflict between "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" and "mscorlib, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes".

(TaskId:77)

There was a conflict between "PCLStorage.Abstractions, Version=0.9.6.0, Culture=neutral, PublicKeyToken=286fe515a2c35b64" and "PCLStorage.Abstractions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=286fe515a2c35b64".

(TaskId:142)

These errors appeared after adding the Microsoft.Build.Async (1.0.168), Microsoft.Bcl.Build(1.0.21), Microsoft.Net.Http(2.2.29), Microsoft.Bcl (1.1.10) nuget packages to my PCL project, Xamarin forms project and Xamarin Droid project.

In addition, the Nuget packages Xamarin.Forms.Maps (v2.1.0.6508) and Xamarin.Forms (v2.1.0.6508-pre3) are used.

Adding the nuget package PclStorage v1.0.2 to the PCL project resolves both warnings and the deployment error.

I'm not sure why this dependency is there.
