How to reduce $ (TargetFrameworkVersion) for FormsViewGroup.dll from (v7.1) to (v6.0) in Xamarin

Question

I am new to Xamarin. I installed VisualStudio 2017 with the Xamarin component and my Android sdk file has been updated to Android (v6.0). I created a new Xamarin project and I get errors:

Severity    Code    Description Project File    Line    Suppression State
Warning     The $(TargetFrameworkVersion) for Xamarin.Forms.Platform.dll(v7.1) is greater than the $(TargetFrameworkVersion) for your project (v6.0).
You need to increase the $(TargetFrameworkVersion) for your project.    App2.Android    C:\(PATH-TO-REPOS)\repos\App2\App2\App2.Android\App2.Android.csproj     

I do not want targeting (v7.1), please tell me where I can update $(TargetFrameworkVersion)for FormsViewGroup.dllto the target (v6.0).

There is already a similar question raised by someone here . But I did not find a solution to reduce the version for FormsViewGroup.dll. Instead, they suggested updating the Android SDK. But I do not want to target (v7.1).

Please offer me an update $(TargetFrameworkVersion)solution FormsViewGroup.dllfor the purpose (v6.0).

thanks
