Your project does not reference "MonoAndroid,Version=v9.0" - visual-studio

Question

As google is requiring all new as well as updates to target api level 28.
I have a xamarin android project using visual studio on the PC
Doing so I can not get past the error:
Your project does not reference "MonoAndroid,Version=v9.0" framework. Add a reference to "MonoAndroid,Version=v9.0" in the "TargetFrameworks" property of your project file and then re-run NuGet restore.
My project doesnt currently have any nuget packages, so i am completley unaware what they are asking for here.
I have of course attempted to target v9 in the project properites. This of course updates the project and manifest as expected.
Ive long had the 28 sdk installed, but sure to update my sdks using not only the MS repo but the latest released on the google repo...
Ive also been sure that the correct Mono.Android.dll referance is used and exists:
\ReferenceAssemblies\Microsoft\Framework\MonoAndroid\v9.0\Mono.Android.dll"
Finally i went and upgraded to Visual Studio 2019 thinking that would fix whatever i have screwed up but it did not.
I then proceeded to try targeting android Q that didnt work either. so im stuck at v8.1 or below.
Ive scoured the internet for answers.
Suggestions ive tried are to be sure the project did not have the Use Latest platform tag, and to run as administrator
Any suggestion apprecated.
Update in response to comments:
Repeating what i said above. But to provide proof,
I have of course attempted to target v9 in the project properites. This of course updates the project and manifest as expected.
Here is the project file stating the version targeted:
Ive long had the 28 sdk installed, but sure to update my sdks using not only the MS repo but the latest released on the google repo...
Here is the manifest indicating what is targeted:
The target version as viewed in properties
And the compile version set
And the current content of the sdk manager
though i also tried using the google repository and android Q
And here is the project file contents:
(I should note contrary to the above ive added a nuget package to see if it helps anything)
